Our take on the Iron Out IO10N Rust Remover

Iron Out IO10N is a 152 oz (about 9.5 lb) jug of powdered rust stain remover for sinks, toilets, showers, tubs and other ceramic and porcelain surfaces. It is a bulk tub of the same iron-reducing chemistry Iron Out sells in smaller bottles, mixed with water and rinsed off after it works. At $30.43 at Max Warehouse as of November 3, 2026, it is the lowest of six store prices and works out to roughly 20 cents an ounce, cheap for a product you dilute and use in small amounts.

Questions and answers

Is the 152 oz jug worth it over the small bottle?

Sprinkle a few tablespoons into the bowl, add hot water, let it sit for 15 to 30 minutes, scrub, then flush and rinse. For heavy rings, repeat or use a stronger mix.
