Eddie-

    I can see your problem- John's post never takes a stand other than "prep 

carefully". You might want to narrow your search down by saying what type of 

paint you intend to use (Enamel, lacquer, etc.) and see if anyone bites.

    Good building.

It's actually not an alternative but rather the  norm in the finishing industry.  Aluminum parts going thru a  conveyorized parts washer (long tunnel with several tanks and hundreds of  spray nozzles) use some pretty aggressive chemicals sometimes depending on what  they are trying to remove but for alum that started out clean and only has  smudges and oils from our skin plus oily residue the air drill spit out Dawn or  Woolite plus water gets it down to the shine. RINSE WELL WITH AGITATION !!   Skip the alcohol, the part is already clean. DON'T dry it with compressed air, a  LITTLE oil in the air goes a long way, use a fan or a CLEAN cotton  rag. 

 If you were outside I'd use WO-1 or Alumaprep to  put in a little tooth for better adhesion but you can do that with the proper  color of Scotchbrite (I keep forgetting which color it is)

I was searching the archives for a good alternative to cleaning parts  before priming (indoors) and found John Bolding's writeup below. 



So,  what is a good, safe cleaner that I can use indoor without risking exposure to  carcinogen chemicals and without causing chemical reactions on the aluminum  parts? 

Should I consider using soap and distilled water followed by rubbing  alcohol?

Thanx...Eddie

Eddie-

    Figures, 15 minutes after I post this, John comes through. Can't 

complain though, eh?

    Good building.
