REFLECTOR: Degreaser recommendation

[Hiroo Umeno]

Does Denatured Alcohol penetrate deep enough to get rid of oil that has saturated up to about 12" of foam / fiberglass sandwich?  If it does, that would be the ideal solution since they are cheap, plentiful and easy to handle.

Alex ... You are absolutely correct sir! Alcohol is great for cleaning and degreasing.  I often use it in a siphon sprayer to clean parts and even electronics.  If you atomize it properly ... It will evaporate quickly and never lay around long enough top hurt anything.

I use denatured alcohol .  Its not as aggressive as some but is easy to acquire and not very toxic to you or the environment.

Hiroo-

You can use Freon to degrease the structure- will penetrates the glass and will take all of the oil with it as it drips off- if it can not drip off, then it will leave the oil where it evaporates- just watch your hands for cold if you decide to go with it- will not otherwise affect anything but the oil.

In about 20 some hours of flying, the bottom half of N21HV is pretty saturated with mineral oil.  I had a very slow leak at the nose cooler that went undetected for a while that puddle the oil on the nose that soaked into the fuselage bottom foam.  It is to the point where the co-pilot side floor is slimy.  The rear-end is also quite oily from the Franklin spitting and dripping oil everywhere.



So, I am in search of a good de-greaser but I am a bit confused by all the choices. Here is what I am looking for...



Pri-1

*         Deep penetrating (into the foam and fiberglass structure)


*         Non-corrosive (safe for metal structure)


Pri-2 (nice to have)

*         Non-toxic  / easy handling




In general, how do they work?  I do know for surface degreaser, you apply them and wash them off but for the soaked-in foam, how does that work?
