GROUT STAIN REMOVER | Cement, Limescale & Grout Residue Remover. For Interior & Exterior use (1L)

Worked brilliantly on removing grout stains that were almost 6 months old.

I recently had my small conservatory floor laid with pale terracotta-effect porcelain tiles and a dark grey grout. The (excellent) tiler washed the tiles over after grouting but advised that I wash the tiles again when the grout had fully dried after a day or so to remove the hazing resulting from using a dark grout with a pale tile. I researched how to do this properly and decided to try this grout stain remover. I used the remover exactly as directed (diluting one volume the remover with 4 volumes of tap water) and applying the solution generously with a cellulose sponge while wearing protective gloves since the remover is quite acidic. I then rinsed the solution off by rubbing the tiles with plenty of plain tap water and a microfibre cloth. I was surprised by the amount of hazing removed since I hadn't thought there was much hazing present, but I was really pleased with the result - the hazing was completely removed without apparently damaging the tiles or grouting and the tiles were left looking very clean, pristine in fact, just as I hoped and without a lot of work.

Did definitely make things easier but it is quite strong and irritated my eyes and hands so you definitely need to wear gloves.

Excellent product, I used it to clean a mosaic floor that was over a hundred years old. Tiles came up brilliantly 👍

Did not work on my tiles however after researching i needed a alkaline product where as this is a acid
