Remove Rust Stains on Bluestone Pavers

The Beauty of Properly Maintained Bluestone

I have been writing about Rust Stains on Bluestone for some time because we regularly have clients who either have naturally occurring rust from the inherent mineral composition of the stone, or accelerated rust stains due to someone cleaning Bluestone with Muriatic Cleaner. SPOILER ALERT – DO NOT USE MURIATIC CLEANER ON BLUESTONE!!

Fortunately, we have had great success solving most of the ‘Bluestone Emergencies’ by using our Two-Step Cleaning process using our Professional Grade Rust Remover from HMK Stone Care, followed by protecting the stone using our Impregnating Sealers.

Rust can occur naturally in Bluestone

Rust or iron minerals do occur naturally in many stones, and quite often in Bluestone, but normally do not become as bad as the image above. This bluestone was cleaned by a stone mason using Muriatic Acid, not knowing that it would accelerate the formation of rust by oxidizing the minerals. This image was taken just two days after cleaning, so naturally the homeowner was quite concerned. She contacted us for a solution, and we recommended the HMK R777 Rust Remover, followed by neutralizing with the HMK R155 Intensive Cleaner. We offer this convenient Combo Pack.

Rust Removing Combo Pack for Natural Stone

Once the Bluestone rust stains are removed, it is essential to protect the stone from further oxidation by sealing the stone with a professional grade impregnating sealer like HMK S234. This quality Impregnating Sealer also has stain protection for areas where food or other stains may occur.

Impregnating Sealer with Extra Stain Protection

For areas that only need to protect agains water and natural elements, we offer a superior Silane based Impregnating Sealer, that is also very economical, HMK S231

Silane Stone Impregnator – HMK S731

How do you Care for Marble?

How do you Care for Marble? Just A little Soap & Water….


clean marbleSoap and Water is not your friend when it comes to cleaning Marble Surfaces

You may have seen this dandy floating around the internet, suggesting that “Just a little Soap and Water” is all you need to clean your precious Marble countertops….but this is not great advice. This is why:

  • Dish soap is highly Alkaline. This is why it cuts grease so well. Some dish soaps are pH 12-14. If you remember from high school chemistry, that pH Neutral is 7.0. High alkaline cleaners will degrade any sealers that you may have on your stone.
  • Soap and Water over time can actually build-up on your marble surface and also darken stone. As your sealer (if you have one) begins to degrade over time, the stone will become more absorbent and the marble (especially light colored marble) will get darker.
  • Dish soap and water will not ‘Condition’ your stone, rather, it will ‘De-Condition’ your stone making it easier to absorb stains, particularly oils.
  • Many stone sealers are Water-Based, and will degrade quickly when using a harsh cleaner like dish soap and water.

What’s a Better Option?

Using a professional grade pH Neutral maintenance cleaner is the best thing to clean your delicate Marble, Travertine, and Onyx surfaces. I have used and recommend the HMK Stone Care P324 concentrated Stone Soap. This highly concentrated maintenance cleaner will not only do your Daily Cleaning, but over time Condition your stone with their proprietary formulation. Developed in Europe where they have installed natural stone for millennia, the Professional Grade products from HMK Stone Care are known throughout the world as the product for stone professionals.

For more information from the US Importer, please see HERE
When mixed in a spray bottle, one liter of HMK P324 Stone Soap will cover 8000 square feet of stone. Simply spray your countertop and wipe dry to clean and condition your stone. This daily cleaner also supports the sealers, even if you chose to use a water based sealer. We recommend the HMK S232 for marble and travertine surfaces. For dark dense stone like granite countertops, we believe the solvent class of sealers do a better job of penetrating the stone and protecting against stains, particularly oil and grease stains. We recommend the HMK S234 Impregnator.

Bottom Line…

Dish soap and water is made for cleaning dishes and greasy pots and pans. It is NOT a good choice for delicate marble surfaces. Protect your investment by using professional grade Stone Care products from HMK Stone Care.

What is Better…Granite or Quartz Countertops?

Don't worry about sealing natural stone like OnyxThe Great Debate – Natural Stone or Quartz?

Natural Stone including this beautiful Honey Onyx are very hard to mimic with Quartz or Porcelain surfaces, and yet many are afraid to use Natural Stone because of the myth that, “It’s Hard to Take Care Of”…. Lets examine this further (see Four Reasons to Chose Natural Stone)

Boiling it down to the essentials, in spite of the fact that there are many amazing man-made products available, NOTHING truly can replace Authentic Natural Stone. The natural coloration, veining, crystal structure, and natural image depth is difficult to reproduce even with modern technology like Reveal Imaging.

Concerned About Caring for Natural Stone?

Protecting natural stone surfaces is the primary concern for most consumers. In fact, it is quite easy to protect most natural stone surfaces by using a Professional Grade stone Impregnating Sealer. We promote the German brand Moeller-HMK Stone Care, as they were one of the first companies in the world to develop not only a Stone Sealer, but a complete Stone Care System. HMK products are distributed to more than 40 countries.

When applied correctly, a quality impregnating sealer will provide years of stain protection and allow you to enjoy the beauty that only nature can create. Please see our VIDEO on the correct way to apply Impregnating Sealers.

Daily Stone Maintenance

One of the easiest ways of caring for natural stone is to maintain it daily. This is not a difficult task, rather quite easy. Simply add 1-capful of HMK P324 Liquid Stone Soap to a 16 oz. spray bottle and fill with water (filtered is best). Then spray your counter area after use, and wipe dry with a paper towel, cloth towel, or Premium Microfiber towel. Your Granite, Marble, or other Natural Stone counter surface will be sparkling clean. PLUS, with regular use of HMK P324, it preserves the sealer, prolonging the need to re-seal.

That’s All There’s To It!

If your stone has been installed for some time, and the shine is dull or you have stains and smudges, you should likely perform a Deep Cleaning to remove the buildup of old cleaning  products, and prepare the stone for a fresh application of penetrating (Impregnating) sealer. We suggest using HMK R155 Intensive Cleaner. This is a highly concentrated cleaning product designed to remove grease, grime, polishes, waxes, and light stains.

Removing Oil Stains from Granite Countertops

Do You Have Oils Stains on your Granite?

Actual Customer Issue Resolved

Wendy writes:
“Our granite countertops are almost 2 years old. Our kitchen counter has an extended area that we use for eating. This area has darkened around the edges where our arms and hands rest on it during meals. What is the best way to lighten that area (remove oil stains) Thank you for your help”


Granite and other natural stone surfaces are absorbent. Some granite, particularly lighter colors, are more absorbent than darker colors, and over time they will get darker where we often touch it with our skin. The oils in our skin as well as lotions used may come in contact with the stone and darken it. This condition needs a Deep Cleaning.

We always recommend the least aggressive solution first, then graduate to more aggressive options as needed. Please see the following steps:

clean granite

Perform the Deep Cleaning using our HMK R155 Intensive Cleaner. Despite the name, it is a very safe cleaning product for all stone, but it does wonders. Mix a solution of 1-part R155 to 5-parts warm water. Soak a cloth in the solution and cover affected or stained area with the saturated cloth and allow to soak in for 15 minutes, re-soaking the  cloth every 5 minutes. After 15 minutes, scrub area with a scrub-pad, then rinse very well. Allow to dry, then observe effectiveness of the process. Repeat as needed.

For stubborn stains, or deeply imbedded stains, you may need to use a poultice to draw-out the stain. We suggest using our HMK R152 Stain Removing Poultice.

granite poulticeThis poultice uses a chemical reaction in the paste to draw out the stains as it dries. I have found for best results perform the Deep Cleaning process first, then immediately apply a layer of the R152 paste, 1/4″ thick over stained area and cover with plastic wrap, taping down the edges. This process allows the poultice to dry much more slowly, to draw out the stains. It may take 2 days for the poultice to completely harden. Scrape off the poultice with a plastic spatula or puddy knife then immediately wash area with the R155 solution. Rinse very well (the R155 is very concentrated) and allow to completely dry. Observe results. Repeat if necessary.

These two products have been VERY effective at removing deeply imbedded stains in granite, marble, travertine, limestone and other natural stone surfaces.

remove ink from graniteFor non-organic stains like Ink, Dyes, Fingernail Polish, Mineral Oil, and other non-food oils, we suggest using the HMK R154 Stain Remover prior to using the Poultice.


We offer a Kit that has both R152 + R155 HERE

Which is Better…Granite or Quartz Countertops?

I came across an interesting article comparing Quartz and Granite Countertops that I thought I would share. See LINK

Whether you chose Quartz or Granite, you still need to clean them regularly to keep the polish sparkling. We suggest using our HMK P 324 Stone Soap Concentrate. This professional grade daily maintenance cleaner will not build up on the surface like many ‘Clean & Polish’ products. Simply pour one capful of P324 into a 16 ounce spray bottle, and fill with water. When you need to spruce up your countertops (P324 is great for marble and travertine also) simply spray your stone counters and wipe dry with either a paper towel, or a microfiber cloth. We offer several kits on our website HERE

Correcting Myths and Mistruths about Sealing Granite & Marble Countertops

 I had a few moments the other day to sit down with a cup of coffee and search the internet about “sealing granite countertops”, and I came across a website that had some good information, some confusing information, and some really bad information. I have decided not to publish a link to this particular website, but suffice it to say, there are numerous such sites on the web.

Of particular interest was a section that talked about ‘How A Granite Countertop Sealer Works’. A true fact is that most (impregnating) sealers do “slow down the process of absorption”, giving you time to clean up spills that have the potential to leave permanent stains. This is certainly true for high quality impregnators that are either solvent based or water based. What was not indicated in the website is that for some materials, there are topical acrylic sealers that do prevent ALL liquids and spills from penetrating the stone because the acrylic acts as a barrier. Tumbled Travertine, Tumbled Marble and Slate are prime candidates for topical acrylics, but NOT in wet areas, or on exteriors.

Some types and finishes of stone look better using a topical acrylic rather than an impregnator. See the following LINK for slate with a satin finish sealer.

clean wine stains on marble and granite

Don’t Panic ~ Wine Spills  on Granite or Marble

The Holidays are here, and Family and Friends are visiting for holiday festivities. It is likely in all the fun and activities that someone may spill food or beverages on your new marble or granite countertops….and you may begin to freak out if you can’t immediately clean up the food, or you see a dark or colored stain. Don’t Worry, it’s Not Permanent if you follow a few tips:

  1. Mix a solution of Dish Soap and Warm Water…as if you were cleaning a greasy pot
  2. Saturate a washcloth or rag in the solution and cover the area
  3. Go back to the Holiday Fun and Enjoy….YES relax!!
  4. About evert half-hour, rinse out the cloth and repeat Step-2
  5. Do this as long as you can, or until you see the stain has been removed.
  6. Go to bed as usual with soaked cloth over effected area.

Next Day, rinse the area well with a clean cloth and blot dry with a towel, and allow to dry for several hours. Observe the area to see if the spot or stain is completely gone. If the spot has been removed then you can go on and enjoy your life. (you still may want to seal the stone). If you still see a spot then you may repeat the steps above to see how effective this may be, or move on to more aggressive cleaning products. We offer several products:

HMK R155 Intensive Cleaner is a mildly alkaline Heavy Duty Cleaner. R155 is very effective at cleaning mild food stains, hard water deposits, and built-up soap scum from all natural stone surfaces. R155 is a highly concentrated cleaner.



HMK R152 Stain Removing Poultice is a Professional Grade Poultice which chemically draws imbedded stains out of Natural Stone surfaces like Marble, Granite, Travertine, and Limestone.


HMK R154 Stripper and Stain Remover is a Professional Grade solvent based cleaner and coating stripper. R154 is great for non-organic stains like Ink, Petroleum based oils, Permanent Black Marker, Fingernail Polish and similar non-food stains.


Of course the best way of preventing Stains on Natural Stone is to protect your natural stone surfaces with a Professional Grade Impregnating Sealer. For a natural look (does not darken stone) we recommend our HMK S324 Impregnator 



If you are looking to Enhance your Natural Stone surfaces then you may want to use one of our Color Enhancing Sealers like HMK S242

Holiday Entertaining – And Wine Spills on Granite or Marble Counters

With the Holiday Season fast approaching, you may be concerned about how to protect your natural stone surfaces from the inevitable spills that occur during festive gatherings.

Well, with just a a few professional stone care products, you can rest assured that your beautiful natural stone won’t be permanently damaged. The key is proper treatment with an Impregnating Sealer. After using the HMK brand of Stone Care products for more than 30 years, I believe they are Best-In-Class. The flagship product for HMK Stone Care is the S234 Impregnator.

To see just how effective this sealer is, please see our video featuring spilled red wine that sat overnight on granite countertops. HERE

If you spill Oil, Cranberry Juice or Sauce, or Wine on Marble or Granite, here are emergency tips to reduce or remove the stain

  • Wipe/Blot up as much as you can with paper towels
  • Immediately make up a solution of lukewarm water and dish washing soap 
  • Soak a washcloth in the solution and cover the stain area. Allow to sit for 20 minutes
  • Repeat, Repeat, Repeat
  • If after several hours of soaking area, you still see a stain then we suggest you order our Poultice Combo
  • While you are waiting for your order to arrive, keep a soaked rag on the spot. This will help prevent the stain from “setting”

To prevent such horrors from occurring, we highly suggest you seal all light and medium colored granite and marble surfaces with the Impregnating Sealer. This is very easy to do, and you do not need to hire a professional. Please see our video on How to Seal Granite Counters
