Mineral Magic is an acidic cleaner designed to dissolve calcium, lime, and rust deposits. It uses organic acid salts that provide a safer handling profile than harsh industrial acids while still being effective on hard water films. It is particularly useful for cleaning fiberglass and acrylic shower inserts where abrasive cleaners might cause scratching.
The 32oz bottle is made of HDPE 2, which is resistant to acidic formulas but can be sensitive to extreme temperatures. Because the solution is thin, it may run down vertical tiles quickly; applying it in stages or using a sponge to keep the area saturated for at least five minutes will yield better results. Performance may slow down in very cold environments below 60°F.
Specifications indicate the trigger sprayer is made with a stainless steel spring to resist corrosion. However, the mineral-based solutes can sometimes dry within the valve if the bottle is stored for a long time without use. Rinsing the nozzle with warm water can help restore the spray pattern if it becomes uneven. Always ensure proper ventilation when using acidic cleaners in enclosed spaces.
