I Saw It On The Internet, So It Must Be True!
You’ve searched the internet and found various conflicting opinions about how to remove stains from granite. Well let me tell you…you cannot always believe everyone on the internet. It is sad to say, but there are many so called experts out there giving dubious advice about cleaning and maintaining natural stone, marble and granite. Some of the advice is good, but much is simply hooey!
All “Experts” are not Equal!
Here is an example:
The “advice” suggests making a poultice, but the method suggested is going to yield very poor results on most medium and light colored granite…the very colors susceptible to staining if not properly sealed. This may be a ‘dressing’, but it is not an effective poultice.
An effective poultice uses a chemical reaction utilizing a medium such as clay or plaster, combined with a reagent to draw oils or stains out of the granite. The proper methods utilize heat to draw the stain into the medium, being clay, plaster or other effective medium.
The video also indicates that citrus juices can harm your granite. This is not accurate. Granite is a Quartz and Feldspar based stone that is acid-resistant. Common household foods will not etch granite. These acids will however damage sensitive marble’s and onyx which are calcium based stones and acid-sensitive.
