Cleaning hardened grout or concrete out of an acrylic bathtub?
Contractor left an unsightly mess in my acrylic jacuzzi tub. It would seem grout or concrete buckets were washed out in my tub and excess product hardened to the surface. I've managed to pry the large chunks out, but there's a fair amount of residue that stubbornly remains. The base of the tub has a slightly pebbled finish which seems to be part of my difficulty in scrubbing it off.
Any advice would be greatly appreciated.
