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

SHOUT is the best-performing stain remover pen brand in July 2026, moving 150,000 units across 3 ASINs for 42.9% of Top 10 volume. Miss Mouth's follows with 130,000 units (37.1%), ahead of Tide on 50,000 units (14.3%).

With 5 brands splitting the Top 10 and 94.3% 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 $6.30 to $12.45, 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: B007ZM1384 booked 10K units at $11.98, with ▲ 0.0% MoM change. On the growth side, B000BGK968 leads positive momentum with ▲ 400.0% MoM growth on 1K units, with B01BHSTKPE 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
