HG Grout Cleaner Spray 500ml

I sprayed this on the floor tiles, waited a couple minutes, and the black gunk in the grout lines just lifted off with a quick scrub. Didn't need to soak anything overnight like I usually do.

Our shower grout had years of grey buildup and I figured it was permanent, but two rounds of this lifted almost all of it. Spraying liberally and letting it sit for a couple of minutes does the work, no scrubbing until my arm aches. The 500ml bottle is lasting longer than I expected too.

The grime between my shower tiles has been there for years and I'd basically given up on it. Sprayed this on, waited a couple of minutes, and it wiped right off with barely any scrubbing. Wish I'd tried it sooner.
