QUESTION
Cleaning Granite Stains - I have a granite counter top and it appears that it retains heat marks from a cup. I thought that granite is the most heat resistant stone, why are there heat marks from a cup? Is there a way to clean or seal the stone so that there will be no heat mark?ANSWER
ANSWER - I have never heard of granite showing heat marks. The natural granite itself should not be affected by heat.My guess is that there is some coating on the granite such as a sealer that is reacting to the heat. You may want to remove any surface coatings and then seal with a penetrating type of sealer.
You should contact a company that specializes in stone cleaning and sealing products, such as those listed in Cleaners and Sealers in the Expert Answers in the Resources column. Good Luck!
