Hi Maurizio, I have read info on your site to remove a couple of stains from my granite kitchen countertop. I went out yesterday to purchase 30 volume hydrogen peroxide (to remove a ring left from a tomato)from a beauty supply store. The product the clerk showed me is Clairoxide and lists the following ingredients in addition to hydrogen peroxide: Water, Cetearyl Alcohol, Ceteareth-25, Salicylic Acid, Phosphoric Acid, Disodium Phosphate, Etidronic Acid. Is this the correct product? The clerk said there is no straight up hydrogen peroxide at 30/40 volume. Also, I purchased baby powder to make the poultice. The powder lists talc and fragrance as ingredients. I could not find a product that was straight up talc. Is talc with fragrance safe to use? Also, I purchased Pure Acetone(to use on an oil stain from my cutting board) from the beauty supply as well and the only ingredient listed is acetone. I assume this is the same type of acetone I would find in a hardware store, right? Finally, once I am able to remove the stains I am planning on using your MB-4 sealer on my countertop. How do I properly clean my counter top before I seal (make sure all residue, etc is removed)? Will your MB-5 cleaner be all that I need? I have not purchased your products yet but want to make sure I am using the correct products for my counter top. Thanks so much for your time. Ann

 

Dear Ann:

 

“ The product the clerk showed me is Clairoxide and lists the following ingredients in addition to hydrogen peroxide: Water, Cetearyl Alcohol, Ceteareth-25, Salicylic Acid, Phosphoric Acid, Disodium Phosphate, Etidronic Acid. Is this the correct product? ”

 

No, it does not sound like the right product. It is kind of milky looking, isn't it? Get the clear type: that should be 100% HP.

 

“ The powder lists talc and fragrance as ingredients. I could not find a product that was straight up talc. Is talc with fragrance safe to use? ”

 

Yes; the presence of fragrances is inconsequential.

 

“ I assume this is the same type of acetone I would find in a hardware store, right? ”

 

Right.

 

“ once I am able to remove the stains I am planning on using MB-4 sealer on my countertop. How do I properly clean my counter top before I seal (make sure all residue, etc is removed)? ”

 

I'd use acetone a couple of time for a really deep cleaning. So you may need more than the little bottle you've got at the beauty solon.

 

“ Will MB-5 cleaner be all that I need? ”

 

For cleaning, yes, it's all you will ever need. If you want to… “liven-up” your countertop from time to time you may consider MB-13, as well.
