I am in the tile business for over 22 years and one major issue in this trade is inconsistency of brand new grout colour after drying, and dirt accumulating on the grout lines over the years. Even though hardware stores have tools that claim to take care of these problems, none of them are efficient in doing the job. I made a professional innovative tool, unmatched by anything in the market, that truly does the job. PROVEN.
I do not have a patent for cost reasons. If anyone is interested in buying my finished prototype, contact me at: najoua.zarrai@hotmail.com and/or at
