will the muriatic acid work on mirrors also. i clean a huge home that has a massive whirlpool tub and a "garden" (with real dirt/plants) planted around its perimeter. behind all of this is a mirrored wall with gross white chalky-looking spots all over the bottom portion of the mirrors from the water that has splashed on them from watering the plants with the shower massage attached to the tub. very rural location. their home is a mile down a dirt road 20 miles from civilization. so lots of well water issues here.
i have tried everything and perhaps the mirrors are etched. just curious. can you scrape the mirrors with a blade or use the acid and steel wool on mirrors? the homeowners feel that there is no solution but if i could fix it, i would love to.
