Last July I published an article about “Homemade Granite Cleaners”
WIKIHOW IS WRONG About Granite Cleaners!
The issue is these (well intentioned) solutions can actually harm natural stone surfaces, especially polished marble, travertine, and onyx because of the higher alkaline content and use of isopropyl alcohol.
Another very popular website offers a similar Homemade Granite Cleaner recipe. Nature’s Nurture offers a recipe that also contains dish soap (pH from 9.5-14.0) that is highly alkaline and can damage calcium based stone, and alcohol that can break down sealers and impregnators prematurely.
A natural, Green-Friendly alternative is HMK P324 Liquid Stone Soap. This biodegradable natural maintenance soap is highly concentrated, and one liter can maintain up to 8000 square feet. We suggest one capful in a 16 oz. spray bottle. Simply spray stone counters and wipe dry. This is a no-rinse product and will help preserve impregnators and sealers, not break-down the protection.
So doing the math, for less than $30 (with shipping) you can have more than 2 years worth of daily cleaning AND protect and preserve your expensive stone surfaces.

Why do you think that we have had 10,254 page views of our (currently backordered) R52 Stain Removing Poultice for Granite and Marble?
Because granite and marble surfaces are not being adequately protected with professional grade sealers. We get calls and emails every day from customers who “had their granite sealed”, but still have staining issues, particularly from oil spills.
See an Amazon Review of HMK R52 Stain Removing Poultice
We have had so many orders of R52 that it is currently backordered until mid-January. Our Professional Grade stone cleaners and sealers are made in Germany, and even with the best order management systems in place, high demand has knocked us out of stock.
It doesn’t need to be like this if Natural Stone surfaces are protected with a professional grade Impregnating Sealer like HMK S34 Impregnator.
If you are experiencing stains in granite or marble that you cannot remove, please email or call us for expert assistance. 800-380-6881
“Oleophobic” (from the Latin oleum “oil”, Greek ελαιοφοβικό eleophobico from έλαιο eleo “oil” and φόβος phobos “fear”) refers to the physical property of a molecule that is repelled from oil.
When it comes to Granite and Marble countertops and other decorative surfaces, oil is the worst enemy. Even though many granite slabs are Resin Impregnated, oil can still penetrate.
Take a look at the picture here. Both pieces were “Sealed”. On the left with a leading brand that claims to repel both water and oils. The piece on the right was impregnated with HMK S324 Stone Impregnator.
Both pieces received a few drops of olive oil and allowed to sit on the surface for 15 minutes, then wiped off with a paper towel. As you can clearly see, the piece on the left has a visible (and lasting) oil stain.
HMK Stone Care products were developed in Germany and has been the favorite of Architects and Stone Professionals for more than 30 years. Choose wisely when looking to protect your natural stone surfaces.

Preparing for Holiday Spills and Stains
With the holidays quickly approaching, it is good to be prepared for holiday entertaining, and being ready to deal with the inevitable spills and stains. Grease, gravy, butter, and wine can often cause significant stains in un-sealed natural stone including granite and marble.
The most obvious solution is prevention. Preventing stains by using a Professional Grade stone impregnator is the easiest way to have fewer headaches and gray hair. We suggest using HMK S234 Impregnator on all natural stone surfaces. See link:
S34 (S234) NATURAL STONE IMPREGNATOR SEALER 1-Liter
If you do spill something on granite or marble, the best thing to do is immediately flush with a warm water and mild dish soap solution. Saturate a washcloth or sponge and cover the stain for 5 minutes and repeatedly rinse cloth/sponge and repeat.
The next option is to use a quality Deep Cleaner like HMK R155 Intensive Cleaner. See link: R55 (R155) DEEP CLEANING – INTENSIVE CLEANER 1-Liter
For deeply imbedded stains, you may need to use a poultice to draw out the stains. We suggest using HMK R52 Poultice with R155 Intensive Cleaner, offered in a Combo Pack:
STAIN REMOVAL COMBO PACK R52-R55
Preventing stains by using a quality impregnator will help prevent holiday headaches and help to keep your stone surfaces looking great through all the holiday hustle and bustle.

We received a curious email from a customer the other day commenting on our personal touch in an order he received. He noted to his wife, “Look Hon, a human packed this order, there’s a hand written ‘Thank You’ on the receipt”.
In this digital age where robots are packaging many e-commerce orders, some may be happy to know that StoneCareOnline orders are actually packaged by humans. Most often it is Diane or another owner insuring accuracy. Since 1999 we have shipped thousands of orders, and have a 99.7% accuracy rating. We work hard to answer technical questions and ship orders completely and accurately every time, and often write a hand written note.
Even though Moeller HMK is a world wide brand, in North America, most online HMK orders come from a small family run business from Missoula Montana…and yes, packaged by real people. We intend to keep it this way as long as we can.
We appreciate comments and feedback from our customers, and appreciate your business!
We frequently get calls asking about how to Clean and Maintain large stone floors. One of the questions involves what tools and equipment do we recommend. So after handling cleaning and restoration projects for three decades, here are my recommendations:
For floors larger than 200 square feet I suggest a roller bucket with mop wringer.
This type of mop bucket makes it easy to cover large areas with minimal trips to the sink for rinsing. The large bucket handles several gallons of wash or rinse water. There are many options available at Amazon.com
For scrubbing and cleaning very large floors (500 sq. ft. +) then I often recommend commercial floor scrubbers like the model listed below:
This machine is currently available at Amazon for a great price. You do have to purchase the scrubbers separately. I have had a similar Clark machine for more than 25 years and it never gives up. The Clark machines are more expensive but if you have a cleaning business they are well worth the investment.
We also have microfiber mops, pads and microfiber buckets available at our Cleaning Tools page.
For professional grade cleaning products for Natural Stone, please see our Deep Cleaning page.
If you have a specific stone cleaning question, please contact us at StoneCareOnline 800-380-6881 or by Email.
In my last post HERE I talked about how easy it is to Clean Granite. What I should have said is Maintain Granite. There is a difference.
As I have mentioned before, polished granite and marble countertops most often lose their luster and sparkle much like how a diamond ring can begin to look dull. Hand lotions, and even skin oils coat the ring, making it appear dull. With a quick dip in jewelry cleaner, a diamond or other gemstone will regain its brilliance.
Polished natural stone behaves exactly the same way! Polished granite is not coated with a shiny lacquer, rather, it is polished with progressively finer grit abrasives until it retains a shine. Dish water & soap, food spills, and even many household ‘cleaners’ can also build up, coating the polished stone preventing it from displaying its natural luster.
This is where “Deep Cleaning” comes in for natural stone. We have created a Deep Cleaning page that recommends HMK Stone Care products to strip off oils, soap residues and other common films that create a dull appearance.
Following these recommendations will restore the brilliance and luster of your polished granite and marble countertops.

I went to YouTube and entered “Cleaning Granite Countertops” in the search box. The result was 19,800 videos on how to clean granite.
THIS IS CRAZY!
There is a VERY simple answer….Spray and Wipe!
By mixing one capful of HMK P324 Liquid Stone Soap in a 32 ounce spray bottle filled with water, you simple Spray the countertops and wipe with a paper towel or cloth towel, buffing dry. Instantly, your granite countertops are clean, and most importantly, you are further protecting your granite.
HMK P324 is a pH neutral cleaner with stone conditioners. It supports impregnators and will not break down sealers.
