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

Did the job, Had grout residue on porcelain slabs and this removed it all. Mix the solution with water, pour it all over and let it soak for a few mins. Used a nylon brush and scrubbed the grout effortlessly. Some of the slabs had thicker grout, but using it undiluted did the truck.

I tried every home remedy to remove Efflorescence from black bathroom tiles with no success, within seconds of using this remover the annoying white staining was gone, I used it neat however you don't need much and i didnt even need to scrub, just used a sponge to spread out the liquid, fantastic product.

It does work, but it takes some using, as in scrubbing. I had to resort to a drill brush, and even then it was hard work.

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

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.

I hate using chemicals for health and environment reasons but when we had a drama grouting our textured porcelain tiles by trying to do too much of a big surface while the sun came out through our large glass doors I thought I would cry and I will have to break and re-tile it all again. After hours of scrubbing with barely no result since it was so thick in places I decided to try a litre of this grout remover and MIRACLE HAPPENED! with a strong formula diluted only with 30/40% water the grout résidu started bubbling immediately and after leaving it to activate for 10mins before scribing quickly allOver with a hard ish drill set brush (the red ones on Amazon also) and several rincing with a mop and fresh clean water it all disappeared without barely affecting my actual grout between tiles. This process was painfree, odour free ish, and very easy I did it 3m2 at the time and had to go again on a few very thick résidu a second time but it was all done the same day saving my kitchen / dining room floor. I can’t recommend this product enough! Totally brilliant I used under 4 litres for 20m2 of very badly affected grout résidu if it just spotting and clean the haze just a litre will go a long way depending on the surface to cover and if your tiles are textured or smooth. Thanks ever so much to the people making and selling this product!

I don't usually rave about stuff I buy, but I was quite disheartened after having laid cream, Spanish porcelain tiles to create a new patio, only to find rust stains from metal garden furniture and parasol bases, making the over all look, really ugly. (Also I had omitted to seal the tiles!) Oops!Having tried various chemicals like your standard "Patio Magic", Sodium Hypochlorite, Cif, etc., the stains were still there, until I tried this LTP Grout Stain Remover with a plastic pot scourer.I've now cleaned every 60cm tile AND sealed them, and they look like new.I'm no longer stressing about stains from BBQ grease, boot scuff marks or rust as this is the solution!

Need to be used with care. Acidic!
