Muratic acid. Just follow the directions on the gallon jug. You can buy it at about any hardware store.

white vinegar should work ... sprinkle some baking soda on it , let it fizz then scrub with a good brush

Rust stains are readily removed by application of dilute phosphoric acid. Phosphoric acid won't burn the concrete as muriatic can do. A phosphoric acid based product called CRC is readily avilable at hardware stores. It can also be used to clean A/C coils and screen room enclosures made of aluminum.

Footnote: Orthophosphoric acid is what makes cola beverages tangy. Try some Coca Cola.

If the phosphoric doesn't work on the rust- use the muriatic- just dilute it a little- pour it on- work it with a stiff broon and hose it off. You can reapply if necessary. Coca Cola won't remove rust from porous concrete IMHO.

I 2nd Berta's suggestion to remove rust stain from anything -- porous or non-porous surface. Rust doesn't stand a chance against Wink. Erased deep rust stain from carpet almost as easily as it worked on porcelain.

Naval jelly great on metal but never tried it on porous surface.

I just read that lemon juice will remove rust. Worth a try before spending a lot of money.

Zud or Bar Keeper's Friend. Make a paste and smear it on the spot. You can scrub if you need to. Rinse!

@ Sandy, the product is ZEP Sweeping Compound put in on and leave as long as possible. We had a contractor's car leave big oil spots in our drive way and then there were some old ones and it came right up. There is a wheel cleaner by Casterol(can purchase at auto parts store) that will loosen the oil if it still hangs around. Good luck.

Rust stains are easily removed using oxalic acid. That is one of it's specialties. We have used it many times with great success. CP

Cindy, if sprinkler rust is your type of problem then I can help you. It really depends on what kind of rust you have.
