Will product ONLY work if sealer is removed?

I tried your product [ very expensive!] on my shower and expected the "great" results as noted on your bottle. The shower is about 15 years old and the grout is in good shape, other then discoloring. I would assume that this grout was sealed when the tiles were installed years ago. Is that why the yellow is not disappearing? If so, wouldn't you automatically suggest a 'stripper' to be purchased at the same time? Please let me know if your product works without removing the sealer, if there is one. Thank You
Asked by: dave
Hi Dave, If the grout is sealed, it is recommended to remove sealer with a strong stripper to prevent uneven cleaning results. The Grout Cleaner & Whitener is for use on floor grout lines only and should not be applied to vertical surfaces or counter-tops where run-off may cause damage. After 15 years, it’s possible that the original sealer has worn off and is causing the surface to yellow. The best product for your application is the Zep Commercial Shower Tub & Tile Cleaner.
