Anyone know of anything that actually works (and is fairly easy & cheap ) to get rid of the blueing type discolouration that happens around the weld when you weld stainless steel? - The tubes that are being welded are satin polished btw but the finish has to be consistent over the length of the tube after the process so anything angle grinder related is probably out!

hi
you can use a wire wheel that fits into a drill
or a scotch pad that also works

oooh oooh I know the answer.

look at Frosts restoration, they sell some fluid that is supposed to removing the blueing in bike exhausts, presumably the cause i.,e. lots of heat is the same.

I like that blueing effect myself

Bikers use some special polish on their exhausts. Don't know which tho'.

Acid.

Either Peek metal polish or Autosol, both work for me or Blue Away from Frost, but, £18

i googled pickling paste but this came up. looks less horrendously dangerous than hydrofloric acid.

might be worth dropping them a mail and requesting a sample
