Cleaning Magnesium, What is the best way? Options

[ctc911ctc]

Hi,

I have been at it for a few weeks, using GUNK, Brake Cleaner, Electronic cleaners, scrubbing with drill driven scrubbing attachments, Dawn and then assorted other potions.

I am left with a dull stained magnesium. I know that Vapor Blast is the best way, however, I cannot lug the engine to the Blaster outfit,

Has anything worked well for you?

Thank you Teeners!

Replicating the mottled original Mag finish is nearly impossible since most of the chemicals used back then are banned or highly regulated now.

That said this set of original 914-6 covers was restored and touched up using very delicate media blasting (plastic or walnut shells) the pressure is very sensitive. Cleaning with non corrosive degreaser and nothing abrasive ( once scratched its not easily fixed).
Finish touch-up is done with a light acidic solution followed by careful neutralizing.

The final parts need to then be treated with a surface treatment that prevents further corrosion, those details are on many threads.

This set of 4 took probably 10-12 hours in total to get to this state but they are totally as original, if that is your aim.
