Rusty nuts - ooh er
Hi
I've been trying to get some nuts and bolts clear of rust - I've tried malt vinegar, white vinegar, coke but no joy.
Don't really want to wire brush as I dont want to damage threads - they are small headlight bolts.
Noticed in CKC that Ash used Hammerite Rust Remover
Anyone else used this and what were the results like ?
Also the adjuster screws go into plastic grommets - the plastic is stained with some rust. Anything except elbow grease I can use on the plastics
without damaging them ?
thanks
Paul

Acids won't damage plastic.
For cleaning up rusty nuts/bolts etc (I do a LOT of that with the old cars) I use a wire brush in a bench grinder. Before that, a wire brush in a
drill, clamped in a workmate. MUCH easier and safer than holding the drill and object being cleaned.

Reman - I'd only assumed they were specials. They are headlight adjustment screws that screw into a grommet. They have a collar near the
screw head which fits into a slot around the headlamp bowls (these are 7'' MX5 headlights). They were quite expensive when I asked at
dealers. I wanted to try and clean them as there's nothing wrong with the threads they are just a bit rusted.
Sounds like wire brushing is way to go then with screws/bolts and acid on plastic.
So next question - where might I buy acid ??
ETA - thanks for the advice as well !!

Vinegar, citric acid (heard good things about citric acid for cleaning rusty metal, but should work well with plastic. Downside is the seller will
assume you are a drug dealer )or phoshoric acid, sold as rust remover. Guess "wonder wheels" would work too as it contains hydrochloric
acid IIRC.

the hammerite stuff was ok but i still had to finish them off with the wire brush to get the shine back. a wire brush wont damage the threads
Anything With Tits or Wheels Will cost you MONEY!!
