Engine cleaning :-(
Started preparing my bike engine for fitting, being nearly 10 years old its quite cruddy and oxidised ,particularly on the exhaust /forward facing
side. Anyone got any ideas for giving the engine casings a clean, without resorting to nasty scratchy "tools" that whizz round in a
drill!
I wondered abouit using alloy wheel cleaner (alkali) to burn some crud off?
Any thoughts for an easy life?

Don't know how well wheel cleaner would work. Remember it is designed to loosen caked on crap sitting on top of powder coat on cast aluminium
wheels... I think it even has little section on the side of bottle about not using on polished wheels/polished rim sections.

We were very sceptical about using the 'wizzy' things on the engine casing. We tried alsorts ReMan to no avail. We resorted to using
'wizzy' things on it and rather than grind off the aluminium it just takes of the crud. We used the cup type of wire brush rather than the
peripheral type due to surface speeds of the wire. It was also a cheap set from Lidl (IIRC) so it may have been slightly softer than most, which
worked in our favour obviously.
Our block came up lovely to be unbiased.  it took time, but we felt as though there was no real alternative in the end.

Hi Colin.
use alloy wheel cleaner...it'll be fine.
Ive used it once, just wasn't brave enough to leave it on for very long - probabably about 30 seconds to a minute...then repeated it - no ill
effects, but result not as good as I hoped for - was better but not immaculate....
know others than have had better results too with the same stuff....maybe left on longer though
good luck
Colin

this kit has two mops that go in a drill but have low abasion. Ive just managed to polish up 27 year old bike engine cases witout too much effort.
if you have a lot of nooks and crannies, there are kits from same person that have additional smaller mops.
using liquid polish on old casings will take till the end of time if done by hand

I found that a Dremel was excellent for this as it could get in all the nooks and crannies and wasn't too abrasive. It took a while but came up
quite nice in the end.
I thought you would have it all fitted in the car and fired up by now!!
Rich.

Thanks for thre suggestions guys.
Started last night, thought i`d try some of them...
Alloy wheel cleaner..(Hydroloric acid type)Nil point.
(may as well have used soapy water)
Nasty wizzy wire brush thing...Deux point
(not too many scratches either).
Will try some more today, just off to the chip shop for some vinegar!
And then to B+Q for a dremelly thing
Cheers, Colin

I normally set the engine in an old bath (in strong sunlight if possible to heat it up) and use a paint brush to douse parafin or white spirits
liberally over the whole thing for a period of a few days. After that, a quick application of 50% parafin and 50% fairey liquid and then I hose it all
off and possibly hit it again with the mixture if I missed a bit.
The pay isn't very good , but the work's hard.

I wouldn't use a wire brush. It can score the soft aluminium. I'm in favour of soaking it with solvent and letting it sit and then washing
it all off with a surfactant.

Got some "aluminium cleaner" from machine Mart ,un point, save your money, just about as good as washing powder in hot water
Good job I got a flexible drill shaft and some more small rotary wire brushes too
I`m just going to have to put up with the surface scratches, they look better than a deep oxidized crud on my v early engine
Go on, someone tell me its running a bit rich

I'd highly recommend Marine clean, Its non toxix, non abrasive, non everything, which makes it sound really pants, but honestly, its fab.
Mix some with hot water, brush on, leave for a while, brush with stiff brush then wash off.
I've used it on my carbs and it removed all the crud.
You can get it from frost, I've got a big bottle and its lasted ages.
Cheers
David
