Rust.. fast

Goodmorning,I just finished a chair for a donation to the circle school in quarter inch steel and after grinding I want to know what is the fastest way to create rust to cover the grind marks? I know it's in the archives somewhere but cant seem to access it I painted on some salt water last night theres a little rust but its much lighter than the metal surface that was sitting out in the rain for months is there a better solution??......................thanks for any info ......................bob

I have used garden

I have used garden fertilizer in solution with water for a fast rust. Usally spray it on with one of those hand pump plastic jug sprayers from a garden center.

Bob, the big problem is that

Bob, the big problem is that the mill scale, which is an oxide coating, resists rust.
So if you want quick, even rust, you need to sandblast first. After sandblasting, you get rust in a day or two.
I like to use a mild chlorox mix- its cheap, easy to get, and you just mix it maybe 25% with water, spray on with an old windex bottle, and you get rust right quick like.

rust fast

thank you Ries,I already sent the chair to the circle school the auction is on the 18th of feb.I sure hope it makes a little money for the school the salt water I used put a light rusted surface on it I guess anyone who wins it can set it out on the outside for a couple of months to even out the rust ,... thanks again.............bob

Muratic acid will kill the

Muratic acid will kill the mill scale and cause a pretty even rust in a few hours. Over night will make a good cover. You must rinse well.

thank you!

 I thought muratic acid only cleaned I understand now that it cleans the metal to let it rust evenly...thank you very much..........bob
