What reviewers say
Iron Out All-Purpose Rust and Stain Remover
Owners with iron-heavy well water report it clears toilet rings, tub stains and laundry discoloration that ordinary cleaners leave behind. Many say the smell is sharp and the powder needs careful mixing, but few find anything else that works as well for the price.
- Removes old rust rings from toilets and tubs
- Rescues white laundry stained by iron
- Keeps water softeners working with less salt
- Cheap per treatment in the multi-pack
- Sulfur smell lingers during use
- Must rinse thoroughly to avoid residue
- Can stain or pit some metals and stone
- Powder is messy to measure
Iron Out IO10N Rust Remover
Owners of Iron Out products generally rate them highly for lifting rust stains that other cleaners fail on, especially in toilets and on white porcelain. Complaints center on the sulfur-like smell when the powder dissolves, the need to ventilate, and occasional damage to fixtures or grout when left on too long.
Questions and answers
- Which is better for bathroom rust stains?
- Both work on toilets, tubs, and tile. The IO10N is marketed specifically for bathroom and kitchen ceramic and porcelain, and it has a mint scent. The All-Purpose covers the same surfaces plus laundry and water softeners.
- Which is the better value?
- The All-Purpose. At $15.99 for six 76 oz bottles at Fleet Farm, it costs about $0.04 per ounce. The IO10N is $30.43 for one 152 oz jug at Max Warehouse, about $0.20 per ounce.
- Can I use either one in the laundry?
- The All-Purpose is stated for laundry rust removal. The IO10N is listed only for ceramic and porcelain bathroom and kitchen surfaces, so keep it out of the wash.
- Do both need rinsing?
- Yes. Both are powders labeled ready to use and both require a rinse after application.
- Is either one safe for a water softener?
- The All-Purpose is stated to clean iron and rust deposits from water softeners and to save salt. The IO10N listing does not mention water softeners.
- Which lasts longer?
- The All-Purpose 6-pack holds 456 oz total versus 152 oz in the IO10N jug, so it lasts about three times as long for roughly half the price.
