HGGrout Cleaner, Ready-To-Use Tile Grouting Cleaning Spray, Removes Stubborn Dirt, Marks & Stains Between Tiled Walls & Floors - 500ml Spray (591050106)

having read the mix of reviews here i bought this product because some genius put down a small white mosaic flooring in my bath and shower rooms and the grouting was looking distinctly "unwhite". i am happy to say that this product has proved effective ... i applied it over a 1 x 1 m square and left it for around 5 minutes and then went at it with a very firm bristle scrubbing brush and was delighted to see that dirt was lifting out of the grout ... even around the (excuse me) loo base it was effective after a couple of applications. i will confess that i bought another grout clea contains a very mild hydrochloric acid base for exterior use that i then used on a small area for comparison (with windows wide open) and it took it back to looking genuinely like i had just regrouted the entire bathroom. if you don't want to go there with the clear potential risk then this product stands up for itself and the difference is not as great as one might think. i have adhd tho lol

Just spray on the grout and leave for 5 minutes rub off with a plastic brush and wash off after with hot soapy water. works as well as the cleaner for plastic double glazed windows

We purchased the HG Grout Cleaner as an alternative to raking out old and discoloured grout, and it has proven to be a practical solution. While it doesn’t make grout look brand new, it does a good job of making it look acceptably clean and refreshed.The ready-to-use spray is easy to apply, and it effectively removes dirt, marks, and stains from grout on tiled walls and floors. It’s a straightforward process with visible results, and the 500ml size provides enough product for multiple uses.For anyone looking to improve the appearance of their grout without the hassle of replacing it, this cleaner offers a simple and effective way to achieve a cleaner, more presentable look.

Sorting out the grout in my shower felt long overdue – the grey had morphed into something resembling a questionable beige. I tried this product after hearing it was capable of tackling stubborn dirt without harming the tiles. The spray was simple to use: apply, leave for a few minutes, then scrub with a brush. It didn’t solve everything instantaneously; the more ingrained grime required a couple of applications and more effort than I had anticipated. That said, with a bit of persistence, the grout appeared much brighter – almost as though the bathroom rediscovered what clean truly meant. My only issue was getting the nozzle to function correctly. Twisting and squeezing it to open seemed unnecessarily fiddly. Packaging challenges aside, it’s a decent option for refreshing the space whilst being gentle on the tiles.

Highly recommend this product as a quick and simple means to clean up your bathroom floor and wall tiling grout.

Used for floor tiles, did a big job, hallway, kitchen, utility and cloaks.... Still had a small amount left. It did a great job, you do have to still rub quite hard, but the result is great. I'd recommend.

This was purchased to remove an unknown white stain (not that type) from grey grout between kitchen floor tiles. Initialy it was unsuccessful but after a few applications and some light scrubbing it worked whilst similar products have failed.

Did nothing! Followed the instructions and didn't do anything to the grout on my kitchen or my wet room. Waste of money
