How can I whiten a granite countertop that has yellowed ?

Marble, granite, and stone do NOT like having acidic (ie: citrus-based) cleaners used on them. Citrus or vinegar will actually cause “etching” on granite countertops. Not a good thing. Granite countertops also don’t like it when you use something like Windex on them because it strips the “seal” off of the stone.

Apparently there are some very nice countertop/granite cleaners out there that do a great job…but $7.00 for a 12-ounce bottle? YOU can do better than that! :-)

After researching several homemade options out there…I discovered they all had the same basic ingredients…just in varying amounts. Some had a LOT of alcohol in them…some very little. I think the following “recipe” has a good balance of the ingredients, based on the information I read.

Homemade Granite Cleaner, 1/4 cup of rubbing alcohol (or cheap vodka), 3 drops of Dawn or other dish soap (Castile soap would also be a good alternative if you prefer), Water, 5-10 drops essential oil (optional – to help mask the alcohol smell).

Put the rubbing alcohol or vodka into a 16 oz spray bottle. Add the dish soap, essential oil and fill up the rest of the bottle with water.

Now give it a few shakes….THEN give it a try! It should give your countertops a nice, clean shine. Works on appliances too! All at a FRACTION of the price of the store-bought stuff.

Good luck!

I would talk to a granite retailer or fabricator to see what they recommend.

Try a dish washing liquid with Oxy clean in it. Worked wonders on my melmack dishes, clothing, dish rags & Formica counter top. I took the dish liquid squinted it on to my counter top misted with water, let sit for a few minutes. White as they can be.
