Stain Removal Guide

Granite and marble stains are caused when a substance absorbs into the pores of the stone creating a dark spot (not to be confused with etching, which leaves a dull and light-colored spot). Stains cannot be simply scrubbed away and must be drawn out of the stone.
This specially-formulated and powerful DIY stain remover poultice works deep into the stone to lift out and remove the staining substance without damaging the countertop or tile surface finish.  
Most travertine, granite and marble stains are not permanent and can be removed following this simple procedure: 
  1. Wet the area to be treated for stain removal.
  2. Scoop out the amount of paste needed to cover the stain as indicated below.
  3. Apply poultice paste to the stain 1/8 to 1/4 inch (.65 cm) thick and exceeding the edges of the stain 1/2 inch (1.25 cm) . 
  4. Cover the entire poultice with standard plastic wrap. 
  5. Tape down the edges of the plastic wrap with masking tape.
  6. Let sit on the stain for 24 hours. Then remove the plastic only.
  7. After removing only the plastic, do not touch the poultice. The important part comes next... 
  8. Leave the poultice in place until it dries out completely (another 24 - 48 hours). It's this drying action that draws out the stain.  
  9. Remove the dried poultice with a plastic spatula. 
  10. Rinse the area with water and clean it with a stone cleaner. 

Some stains may require repeat applications. Continue with repeat applications until the stain is removed. 


For marble etching (dull spots, glass-rings and water stain removal) use the Etch Remover / Marble Polishing Powder


For hard water stains use the Soap Film / Hard Water Remover


For mold & mildew stains use the Mold & Mildew Stain Remover

Awful product! I followed the directions perfectly and this product generated NEW stains. Help desk emailed me but offered no solution, no refund, and no product to counter the new stains. This product ruined a 2500 table. =========== Countertop Specialty Response ========== We certainly apologize that you had difficulty using our product. We did respond right away to your request for help but could not offer a solution at that time because we needed additional information and photos to properly diagnose the problem and recommend the correct solution. However, we never received a reply or additional information from you that would allow us to provide further assistance. Although you may have followed the directions perfectly, stone care and repair are part art as each case can present different variables. Most often customers can use our products easily and successfully without need for additional guidance. But when complications occur, we are experts that can figure why. But we can only work with the information provided. If none is provided, then we can't help. And the "new" stains you mentioned were almost certainly temporary. Water from the application of the poultice product can darken the stone which may look like a stain once the poultice is removed but this dark spot will disappear as the water evaporates. It's a common misunderstanding of how the product works and what to expect when using the product. Also, the great thing about marble is that it can almost always be repaired and is rarely permanently ruined. You just need to learn the correct solution. And that is what we are here for! Please know that we are always happy to help answer any questions before and after the sale. We have a high rate of success troubleshooting any issue a customer may encounter using one of our products so the desired end result is achieved.

I have to say, I was skeptical at first! I had just installed a granite countertop in our remodeled bathroom. My wife sat a wooden sign on it and a candle (metal lid down). Needless to say, I had a wood stain line and a few rust spots on my brand new countertop. I was devastated. Tried barkeeper's friend at the advice of a local countertop installer. Didn't even touch the stains. I saw your products and figured why not. I had a feeling I was replacing the countertop at this point so I might as well try. Used your products and the stains are gone completely! I have been telling everyone about the products. Any time someone has a stain, I will absolutely be recommending your products. I even told the local countertop installer about it so they knew in the future if they ever needed it or someone else asked. This stuff is amazing! Thank you so much! I can't tell you enough how appreciative I am of such wonderful products that actually do what they say they're going to do!

Did NOT work for me - applied several times and NO Difference. Would Not buy again. +++++++ Countertop Specialty comment: We apologize for you didn't get the expected results. Note that we are happy to help provide diagnosis and guidance. Stone care is sometimes more art than science and some stains cannot be removed no matter the product or method. However, if you saw absolutely no change, it is likely you did not have a "stain" but rather a different issue like etching.

I tried this as a first step to remove light stains - circles, nearly square and other light stains from my Absolute Black Granite. It did not work so I tried acetone next. After reading on this Web site that there are varying types of Absolute Black I am going to next try Methyl Chloride. The poultice powder was worth a try but did not work for me. ******************* Countertop Specialty comment *** The light marks and circles on your black granite are etch marks and not "stains". This Stain Removal Poultice will only remove stains (dark spots). It will not repair or remove light-colored or dull etch marks. Please know we will answer any questions prior to purchase to help diagnose the issue and choose the correct product.
