Mold Stain Remover Gel Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Mr. Clean is the best-performing mold stain remover gel brand in July 2026, moving 80,000 units across 1 ASIN for 33.9% of Top 10 volume. ACTIVE follows with 70,000 units (29.7%), ahead of RMR Brands on 26,000 units (11.0%).

With 7 brands splitting the Top 10 and 74.6% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $12.94 to $25.65, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0D936M5H5 booked 6K units at $26.98, with ▲ 100.0% MoM change. On the growth side, B0CTS8VQ85 leads positive momentum with ▲ 600.0% MoM growth on 70K units, with B0H2Z8RYZP close behind at ▲ 300.0% MoM on 2K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
