– Grout Cleaner Concentrate 500 ml - Concentrated formula for floor, wall and bathroom

The material was tested against a variety of direct applications and surfaces, but it did not perform as expected. It failed to adhere or react properly across multiple surface types and with different direct-use formulations. The results varied depending on the color, finish, and composition of the surfaces involved. But the end result was unsatisfactory.

Does not work as well as advertised. JIF is much better than this product

Excellent product. Best one out there. Restores grout to original color.

Outstanding..... Now... I had a 400ml spray bottle. Put in 100ml HG and 300ml water. I sprayed that over a pretty grubby tiled wet room. To be fair, I have a brush attachment for a cordless drill, they're not expensive and I've had them a long time. I let it soak for 30 minutes, then scrubbed the walls, I could see the grime running off. Rinsed off with the shower and it's GLEAMING. Highly recommend this stuff.

Bought this as a last ditch effort before taking more drastic measures like regrouting. The grouting on my floors have always been kept clean regularly, but the stains have been impossible to remove, darkening over time. I've tried using various mixtures, concoctions and products over the years. This has been the most straightforward and effective. It also required the least amount of elbow grease. I used a medium bristle brush and lightly went over the grouting with long strokes.

A répondu à toutes mes attentes et plus encore. Il a rendu le coulis de mes carreaux au blanc en 30 secondes. Je recommande fortement ce produit

pensavo che si sarebbe comportato come una gomma che cancella tutto. sono rimasto un po deluso. i miracoli non sono frequenti.
