Exhaust header cleaners

[Saloonatic67]

Anyone have tips for cleaning the headers/downpipes ?

What does everyone use ?

I've been giving the bike a "deep" clean while it's off the road over winter and have the rest of the bike gleaming, but the downpipes and the section of the exhaust under the bike still look quite grubby.

Harpic. x10 ……loads of vids on YouTube about it.

Stainless steel polish, tinfoil and elbow grease.. 👍

+1 for Harpic Power Plus. Used it for years without issues.

Waiting now for someone to post the usual “ it’s a strong acid and eats into your headers” story!

I mean it most definitely will absolutely damage the headers, just not in a way that affects it's function. Key is to fully clean it off afterwards, if you have some old header tubing, put it aside spray a little harpic in it and leave it to sit, within days it'll be a corroded, pitted mess.

I use it too myself regardless.

Thanks folks I'll give it a go and be sure it'll get a damn good flush with water afterwards.

This was my Tiger Sport after I had polished using the method in my previous post.. 

2014 bike and untouched for 5 years before I cleaned them. I thought I had a few photos but can only find this one. I painted the top part with a black heat resistant paint.



And no chance of damaging the headers..

Try belgom alu I find it leave a residue that helps get the tar sports off next time but like most have said elbow grease, depending how bad they are a very fine emery cloth.

Did mine recently, mild house anti rust sparingly to avoid getting too deep into the steel and green scotchbrite pads. Good spray of brake clean. Final some autosol polish. Came out pretty good. Had them completely off and disassembled.
