Cleaning up rusty bolts?

Re: Re:

Hydrofluoric acid mixed with phosphoric acid and a few drops of surfactant maybe.

You can asses the risk.

Recycle them and buy some new ones if generic in shape though, it's probably cheap in the long run.

Hydrofluoric acid can be fatal on skin contact.
I won't use it.

I can send you some acid. Welsh red dragons.

I don't think you will care about a wee bit of rust after them.

Wire brush wheel on bench grinder


Failing that
Electric drill with wire brush attachment.

Re: Re:

You can hold the bolt or screw in a cordless drill on a medium speed to help with the polishing.

Hydrofluoric acid mixed with ....

Hydrofluoric is pretty *special* stuff.
It's pretty unlikely any casual forum browsers will come across it, and thise who use it likely know the risks.
If you don't and you find some under your mum's kitchen sink, browse the internet judiciously to understand the risks.... :shock:

Re:

I use a Dremel with either a brass or stainless steel brush attachment.

They also make a narrow brush attachment, which is ideal for getting into rusty hex bolts.

There's rumours of it being in some commercial car wheel cleaners, no idea if it's true though.
