Long Life Grout Cleaner | ProductReview.au
Bought for $10 at Bunnings after reading the positive reviews. Have tried a number of different options to clean and whiten the dirty grout in my bathroom but nothing worked. I sprayed long life grout cleaner on the grout.. left it for 10 mins or so. Scrubbed with a toothbrush and once the grout dried it was significantly whiter and cleaner.
