Does exactly what it says! Excellent

looks good

Does what it says very good

Good product for everyday grout cleaning, struggled with stubborn stains with a darker appearance around the toilet and basin areas. Low odour, removal good and effective as per previous observations. For more stubborn stains use a stronger application.

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

Good price, quality product, it does what it says on the tin ( only 4* come up?)I use this with a grout brush for best results, The whole brand of products I find excellent!I will be re-ordering !

Does a reasonable job. Needed about 3 gos of spraying, leaving for a bit, then scrubbing with a kitchen scourer pad/brush, but most of the grout has come back to a nice white. Some more stubborn discolouring and mould spots have remained. Good enough that I'd recommend

Did absolutely nothing despite repeat applications. Don't waste your money.
