ANSWER

ANSWER - Sealers cannot be removed with acidic products and regular cleaners.  You need to use a sealer stripper.  You should contact the manufacturer of the sealer, if you know who made it, and ask what they recommend for its removal.  If you don't know who made the sealer, then go to any of the manufacturer's of sealers and ask what they recommend for removal of unknow sealers.  They normally say that their sealer will remove most types of sealers, but you need to first test it out to make sure it will work for you.  You can get a list of sealer manufacturers on our website www.CTaSC.com under Resources on the Expert Answers page.

If you are trying to remove the sealer because it was applied incorrectly and is very tacky and picking up dirt easily, then you can consider using the same sealer to apply over it that should dissolve the existing sealer to some degree, so you can then immediately wipe it clean and dry with a lint free cloth.  Be sure to test this method out first to make sure it will work to your satisfaction.  Good Luck.

      If you use a stripper that is meant to remove sealer coatings it will remove it to the extent it can reach the sealer. Depending on what type of sealer you used and how far it penetrated into the grout will dictate how effective the stripper will be. Generally speaking sealers don’t last much more than a year if that in terms of repelling water.
