Bests & Worsts Reviews from Amazon

Please do not buy this product. Several months ago, I purchased grout-ezz from Amazon to clean the grout on my kitchen floor. The kitchen floor is white ceramic tile with white grout. The floor is only one year old. It did clean the gout but ruined my kitchen ceramic tile floor. Because of the pour spout on the bottle, it was impossible to regulate the amount of liquid applied to the grout. Yes it did spill over on the tile. At first, I was not concerned because I followed the instructions and wiped up the access. After drying, I noticed that the cleaner left etching on the ceramic floor. I have contacted Jeff White owner of Clean-ezz and he refuses to do anything about my problem. I have sent him pictures of the floor, verifications from the tile manufactor and a professional cleaner verifying that the etching will not come out. I would like to hear from anyone else who had the same problem. I did notice one person did have a problem. We checked the contents of cleaner and it does have acid in it.
