At some point over the winter I want to internally de-gunk and degrease the exhausts on my RD350LC. I'll also give the exterior a lick over with it, but that's less of an issue as the outside can be blasted. I need to remove the accumulated residue of around 40 years of burnt on two-stroke oil on the internals prior to getting the exhausts ceramic coated.
From everything I know or have heard, caustic soda is the stuff for this job, but I have no idea what dilution/mixing rates I should use. The CS I have is in powder form and I have about 5 kg of it. I'm very aware that it's nasty stuff and I will be wearing long Ansell rubber gloves, eye protection and (when mixing) a Draeger chemical half-face mask. I'm also aware that I must add CS to water, not the other way about.
So - what kind of dilution rate or mixing ratio should I be using. Do two-stroke exhausts need a more concentrated solution? There will be plenty of burnt-on oily gunk in there to remove.
