About a month before Christmas, I noticed what looked like a tarnish build-up on the front sections of my exhaust pipes, apart from the yellowing of the pipes,
and after an exhaustive search for Barkeepers Friend, eventually bought a tin of it from Saaz
This cleaned a huge amount, especially the yellowing around the welded parts, as per the photos:
but I was still left with what appeared to be spots of tarnish or something, which even the Barkeepers Friend couldn't shift.
I showed a couple of mates, one of whom suggested a very light wet & dry paper, but I thought it might leave scratches, so I let that one slide.
The other pal (my bike mechanic) offered an acidic cleaner called S-Weld Brite Wash, which got rid of the spots entirely with the aid of a plastic scourer, but also removed the gleam, which brought on a mild panic attack
I tried the Barkeepers Friend again, but that didn't do much for it, so I then tried a stainless steel polish, which, as you can see, brought back the shine:
The black mark you can
just see in the far left of the last photo is from my boots, but with a bit more polishing, I should be able to get that off too.
Just thought I'd share :)
