Topic: Parts Cleaing Questions

[brad37]

HI everyone,
   I have read a bunch of different opinions across the internet about the best way to clean various engine parts , but have yet to find anything definitive, there is a lot of contradictory advice out there.  I have a 1974 CB550 that I'm currently rebuilding the top end.  I'm looking a good SAFE way to clean my valves and pistons, I had the head surfaces soda blasted ( should have done pistons and valves).  Any advice would be great .  For the valves I was going to use a brass brush on a dremel and follow up with a ultrasonic bath in simple green solution.  I have no idea what to do about the aluminum pistons.
Thanks

You're reusing these parts? I'd probably just use some solvent and a toothbrush. It really doesn't have to be perfect.

Pistons I would use brake clean and a toothbrush. Valves I would soak in berrymans chemdip.

Dawn dish soap is safe on oil soaked pelicans and pistons!

I didn't know pelicans could be trained a garage helpers.

If you had the head blasted, remove the oil galley plugs and flush the head fully. Oil contacting the soda cause it to congeal and clog up those ever-important little orifices.

I don't personally like brass brushes or wheels when used with Dremels. The brass is quite prone to flinging off and damaging eyes, ears and throats.... I do prefer soft knot stainless wheels, or even stainless steel "toothbrush" type brushes. Very effective, darn cheap, and great for aluminum/soft parts without damaging the part. If your pistons are free from the cylinders, you can clean the tops very quickly with one.
