Millteks with Rusty Tailpipe Interiors

[cobraBLACK]

Just bought a second-hand Milltek for my V8 S4 (B6) and the insides of the tailpipes are a little corroded.

I know some exhausts will have a coating inside and I didn't want to risk scrubbing it off.

Can anyone recommend the best course of action?

Here's the nearside pipe (the offside is just the same):

a bit of autosol and some 00 grade wirewool will clean that up nicley, millteks dont have any special coating inside, usally just shiney stainless steel ( for a few hours after cleaning) then its black!! lol

Thanks.

Black's fine; I just don't want brown.

00 grade wire wool leaves scratches in stainless.

It can be hard to find, but it's worth getting 0000 grade. We use Alutech Metal polish; that'd sort those pipes out nicely: Raceglaze Alutech Metal Polish | Raceglaze Car Care & Detailing Products

Just a little addition and I know it doesn't help your problem but stainless doesn't corrode. So either it's not a stainless exhaust or it's some sort of deposit that can be removed with autosol.
