magnesium+"soft" parts cleaning

hi!
i just purchased a bunch of used parts and would like to know the best way to clean them,if possible.
-a used mag psi low profile injector that has black marks on top from restraint straps.
-a blower bag and an engine diaper,both of them "oily" in and out.
thanks

 

Cleaning magnesium? If it still has the Dow 7 coating on it (the green/gold colored coating), DONT try and clean it (especially with anything abrasive), you'll take it all off in no time. Just wipe it down with a little tranny fluid on a soft rag. If the Dow coating is all gone, (It will have a dull gray look, and feel kind of "fuzzy"), then your best bet is to send it back to PSI or Littlefields and have them redo the Dow 7 coating, as it will never look good for longer than a day, because mag corrodes so quickly.

For the blower bag and diaper, 1/2 laundry soap and 1/2 Castrol Super Clean works well.

Good luck
Chris

 

thanks a lot!
the injector looks like it was never coated,as it is completely grey.
i just came across an article in an old hot rod magazine issue about wheel cleaning,and they mantioned the use of baby oil on a mag wheel to keep it clean...is it serious?

 

Don't know anything about baby oil, but Gibbs brand penetrant is said to be really good on mag parts. http://www.roadsters.com/gibbs/
