Stainless headers and acid.....

Postby milleplod » Tue Nov 06, 2018 2:37 pm

I've just spent 2 hours in the garage getting nowhere trying to clean up my RT's stainless headers - I'm sweating like a sweaty thing! :lol: There's years of crud baked onto them - I've tried the superstrong Harpic (9% hydrochloric content), it's barely touched them, despite lots of scrubing and rubbing. A mate suggested a visit to the local powder coaters - he's had various car and bike parts done there, they've got an acid bath for paint removal. Has anyone tried having headers acid-dipped to get the crap off them? Any observations....?! :-k

Hi Pete,
Have you tried paraffin ?
I've found it's quite good at softening up cruddy parts of bike's.

Hi Keith.

I tried paraffin, white spirit, WD40....if it was in the garage, I tried it! :lol: I've found a local metal polisher and am thinking they might be a better choice than the acid bath - if I get time, I'll call inlater to see if they can help.

A metal polisher is the only choice if you want them to be shiny again. Good luck keeping them that way, you will have to wear gloves to fit them and never touch them without cleaning them before you start the engine again.

Hi
paint strippers "Acid Baths" seldom are acid, and usually denature the paint.

No harm asking though.

Industrially we used to use Caustic HOT or Methylene Chloride, COLD with a water seal on top. Dont confuse UnHeated Hot Caustic with the Cold stripper, as an MGB owner discovered when his part dissolved.

Well, I'm rethinking this now.....the headers' part number is 7691717....which means they're bloody chromed, not stainless! :oops: So, I think a metal polisher is the way forward. :lol: I kept the stainless headers on my 1200ST looking very nice during my 6/7 years ownership simply by spending 15 mins every few weeks with some Peek and a cloth - they never looked manky. These RT ones are really, really manky, which I don't like at all! :smile:
