Homemade Rust Eater

So its friday night and the weekends a washout according the forecast.
So i decided to rip my downpipes off as they are looking a tad rusty from the winter.
Has anyone got any suggestions for how to remove the rust from all the hard to reach areas?
Any homemade coctails using household chemicals?
Cheers

like the idea but dont have the kit or 4 days to play with Smile

Need to get them back on the bike for monday.
I'm saving up for some stainless downpipes so these only have to last another few months or so.

You could try soaking a cloth or cotton wool in the vinegar and then wrapping it so that it's in contact with the difficult to reach bits and then cover in clingfilm to keep it from drying out?

That's what you do with taps to get rid of limescale, so not sure if it work on your pipes, but it'd certainly require less vinegar! Wink

Forgot to post the results of the vinegar rust eater Smile

The vinegar removed most of the surface rust and loosened the hard to reach areas making it easier to remove with a wire brush.
The results.....drum roll please.....

Could you strip them and let them rust and start again please because you forgot the 'before' pics. Shifty

Coca cola will eat teeth.. so it might work for rust, apparently the coca cola company has been using it to clean their engines for years xD

Btw.. that probably isnt true.. was in a random facts book i read.. Very unreliable Cool

I know, that's where I got mine. But it's still a lot of vinegar and a big tub to submerge a set of pipes in so I wanna know if he did that or if it was a wrapping in soaked rags kinda thing.

I've got some very rusty downpipes on my project bike and may give it a go at some point.
