Engine case cleaning?
Has anyone stumbled across a method of of cleaning up the alloy cases? don't want to bead blast the cases because i don't want to have to remove the bearings and bushes, and don't want to spend hours taping everything up.

So any chemical options, i could use caustic but it leaves a grey film on everything, so are there any other options?

Chemical stripping works well but it will rip all the grease out of the bearings.

Another option is soda blasting, works very well on alloy and the soda dissolves in water.

What chemical? want something i can do at home, i have a friend nearby who does restoration and i can use his bead blaster to do the head and barrels but just don't want to bugger about too much with the cases.

Chuck them in the dishwasher.

Or get a big pot, add dishwasher soap and let them simmer for an hour or so.

Tried the dishwasher...much to the wife's disgust, not too impressed, didn't come up as expected.:(

Try white vinegar and hot water, and stand for an hour. It will clean out the grease etc but won't leave a smooth surface like blasting with substrate (sand, soda, etc..)

Autosol FTW.

Ferkin magic that stuff is.

A lot of elbow grease required for that though. I'm currently cleaning up a load of Brass plate with it. If you are going down that route then good old T' Cut or Brasso, (pads or liquid) may do...
