Got rust out without any acid spotter.

Ratty apartment with the famous cut pile olefin.

They had a metal table with rusty legs in the living room.

4 big RUST spots on the carpet.

Sprayed the shit out of it with Releasit DS and then HOSTed the hell out of it

The physical brush action must have gotten the rust off of the carpet fibers, because

No more rust spots.

Have any of you tried encapsulating rust?

I've run across it before while on the CImex (with DS) and figured I'd have to go back and acid spot and extract, but it disappeared on me before I had to go through the trouble.

Spot n Boost from Vacaway works half the time for me.

All acids are "bleaches" (although not all bleaches are acids). They all are forms of reducing agents or stripping bleaches, which means they remove oxygen. Some are far more effective at this than others.

Rust is a form of oxidation; the addition of oxygen (iron oxide).

Therefore, any acid can remove rust. However, usually a stronger acid (oxalic, hydrofloric, ammonium biflouride) will be more effective than a weaker acid (acetic, citric, sulfamic).

The fact that the carpet was polypropylene helped.
