    I used CRC and WD-40 for this on my Triumph Speed Triple, and it's great for making black engines look supreme. I would either wipe it on with a cloth, or spray directly and immediately sponge it off.

And yes it will act as a solvent on heavier lubricants - remember chemistry in 5th form? Like dissolves like, and lighter lubricants will act as a solvent to heavier lubricants. This makes it useful for cleaning grease etc off parts.

    Ok i just want to know if i have damaged any thing by spraying the stuff on the suspension beams and wheel/sterring joints/spinning parts, since it acts like a solvent on heavier lubricants as you say is it safe to assume i have to re lubricate or use another chemicle to remove any wd 40 i put on? Or am i safe and all its done is just add more protection as long as i dont cake it on the engine etc so it doesn't cook on to it. ( i also used to to clean the plastics of the bike is that ok ).

    Thanks for your help again .

    The suspension and wheel bearings are sealed (to keep the grease in and water out) - you wont have done any damage with a light spraying of WD40. Nor would it have done any real good apart from cleaning if you wiped it off afterward. Avoid getting it on the brakes in future. And if anyone suggests cleaning the seat with Armor-All - dont.
    it's not a bad thing till you throw a KLR into the mix.

    For a new black engine, CRC and others make a similar product that contains teflon which would be better because it prevents stuff sticking to the engine. These are more expensive and harder to find though, and you should definitely keep that away from the brakes.
    CRC products are sold by Hastings Bunnings (a good range) and MitreIO (a crap range) including one called "Dry glide" - basically spray-on PTFE (=Teflon) sold for lubing curtain tracks, sliding door tracks, thatkindathing. About $15 for a little pray can.

    I'm going to have a go at polishing then respraying one of Mrs H's old stick frying pans to see if it magically becomes non-stick again. One day. When Mrs H is out, so I don't risk becoming unstuck. I'll need time to let it dry (15 mins says the can) and wash it before conducting the official scientific stick test with 3 rashers of the very finest manuka-cured streaky bacon from Hendersons - lovely stuff. And maybe a couple of eggs, freshly squeezed from our chooks. If it works, job's a goodun and lunch is served. If not, I shall go hungry and dispose of the experimental remains.

    Theyre brakes......not breaks. A break is something you should have from over thinking this whole thing.

    You havent damaged anything.......
