Rusty Nuts

Evening All. Hope everyone is keeping safe. Had a bit of time on my hands recently so have decided to give the old girl (07 Spring St 1050) some long needed TLC. Due to her being laid up for a while, a lot of nuts/bolts have started to rust. Mainly brake calipers - foot rests - etc.
Just wondering if there are any tried and tested methods of cleaning them up.

TIA kris

 

Cheers Freck. I will try and get some pics tomorrow. they're not mega rusty but its a bit more than surface rust. if that makes sense.
