View Full Version : removing rust stains from concrete planter

I have a planter made of cast concrete blocks. I water the plants with our iron filled well water, so there are stains. How can I best remove the stains?
Any help would be appreciated.

Iron Out. On the grave stones in our city cemetery toilet bowl cleaner works to clean the granite.

Do I need to worry about contaminating the soil with iron out - will it hurt the plants.

Well the official warning on Iron out is : EXTERIOR SURFACES 1 cup (250 mL)
(Stone, Concrete, Brick, Boats, RVs) 1. Mix 1 cup into 1 gal. warm water. 2. Wet surface with clear water. 3. Apply with brush or sponge. 4. Keep saturated until stains are gone. Rinse. NOTE: Avoid contact with vegetation.
