Windex Refill 1 Gallon Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Windex is the best-performing windex refill 1 gallon brand in July 2026, moving 170,000 units across 6 ASINs for 63.7% of Top 10 volume. Dawn follows with 90,000 units (33.7%), ahead of CloroxPro on 7,000 units (2.6%).

With 3 brands splitting the Top 10 and 100.0% 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 $6.91 to $13.83, 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: B001G1Q7IQ booked 7K units at $6.91, with ▼ 12.5% MoM change. On the growth side, B0FK1DCFKY leads positive momentum with ▲ 200.0% MoM growth on 3K units, with B073R8TC93 close behind at ▲ 200.0% MoM on 600 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
