im looking for a spray on cleaner to remove the usual grime off a set of bike engine casings after a layup. Engine will remain in place whilst I clean it..
Any ideas?

Sadly, Kev, there is no magic solution. (Please forgive double entendre!)

As Aluminium alloys age, oxygen in the air induces the surface to oxidise.

Additionally, various pollutants (grease, oil, road salts etc) become set into the surface.

Today, the correct approach is to sandblast using Sodium Bicarbonate: not the stuff in the kitchen cupboard, btw.

All depends what finish you are looking for: loads of elbow grease and the old trusty Solvol Autosol will produce a good result.

I note now that Clarkes Tools have added Bicarb to their range of blasting grits.

Not bad enough to blast it, may try some alloy wheel cleaner?
Not after a mirror finish, just a cleaner look.

Suck it and see...............seems the cogent answer!

I would go with alloy wheel cleaner agitated with a dishwashing brush, but beware of splashes ~ wear goggles....

Jet wash off.

Then perhaps some Solvol Autosol....

Try Mequiars, I was a Solvol fan, until I tried this cleaner, and would now not go back. The sales literature describes the abrasive particles as smartie shaped, rather than the grit in Solvol, leaving a smoother shine, plus it contains a silicon content to provide a degree of protection afterwards.
When I start with a furry aluminium, I use a 1600 grit wet and dry, then use the polish after that, the finer the wet and dry the better, saves the elbow work afterwards.

Thanks Ka,

will try the alloy wheel cleaner followed by the foaming gunk i think..wont go as far as the Solvol as I just want a clean finish on the castings, they are not smooth enough for a shine and to be honest wouldnt look right anyways.

many thanks
