Rust Stains on Concrete

[OldCoot]

Had rust stains on our drive from the old tt chains and jack pads. Tried everything to remove them and someone suggested "The Works" toilet bowl cleaner. Got a bottle from Dollar General and tried it. Hey, it really works and it's cheap. It removed the stains immediately. You have to use caution as it is very caustic and you have to wash it off immediately.

Nice find...thanks for the tip

I keep a bottle of Muriatic Acid for the job. There's probably some of that in "The Works". Interestingly, although the rust stains disappear, they aren't really removed, but rendered colorless.

For us dummies, can you explain? If they don't come back, which they didn't, and I can't see them, to me they're gone.

I have used lemon juice and a wire brush in the past which works well.

The Works, you just squirt it on and hose it off and the rust is gone. No scrubbing, just let it foam and hose it off.

It removes the rust...and etches the concrete finish. Looks worse than leaving the rust on it. I've apologized to my neighbor for suggesting she try it.

I'm a monument maker and we use Manganese7. It will remove rust, won't harm concrete and we leave it on polished granite with no ill effects. We get it from Granite City Tool in St. Cloud, MN. Granitecitytool.com
