LTP Grout Stain Remover

Really great product. Tried everything scrubbing for a full day to remove residual adhesive from some tiles I had put down and it still hadn’t come off. Spent £12.99 on this and it took about an hour to get it off. I did have to use it undiluted as, even at a 1:1 dilution with water it didn’t work. But undiluted it was fantastic and I had enough left over to get adhesive off the patio outside the back door where I had trodden some of the adhesive in. Well worth the money!

After trying 2 types of rust remover on the brown stains on my porcelain patio with minimal success I bought this. It has a bit of a smell but not overwhelming and being outdoors probably helped. I saw it start working on contact as it went from clear to white and started to fizz on contact. It needed a bit of rubbing with the ltp emulsifying pad and I used a nylon scrubbing brush but as I continued to apply product with a paint brush the stain was lifting. Takes a bit of time, elbow grease and patience but after weeks of trying different things this has worked like a dream. I like the fact you can see when it’s working and there were some marks I could see it wasn’t right for but the stubborn marks I thought were never going to go have now all gone and I’m over the moon! It’s been a cooler cloudy day which made keeping it wet much easier. I tackled the stain a bit at a time to prevent it drying out over the larger patch. The 1L bottle worked great for what was quite a big stain over 1m long and quite wide closest to the wall. Much cheaper than the rust remover and I’ve still got product left from the 1L bottle if needed in the future. Perfect on efflorescence - job (finally) done!

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.

Had porcelain tiles laid needed to get rid of stubborn grout /cement residue had to use it neat but done then job Good price Good service

Used to remove salt deposits in brickwork at the front of my house. This solution scrubbed in undiluted worked quite well although I had to do it 3 times and used bottled water to rinse. It is v strong so use gloves also it does damage stainless steel as I got some on my sink but with a.but if stainless steel cleaner and a scourer it does come off if you do it straight away.

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.

Worked surprisingly well on the grout residue we had on our porcelain garden tiles, mixed as recommended.

Very effective, cleaned up a fairly stained bathroom floor grout and tiles with not too much effort. I was impressed because I've tried other products without much success.
