    Default wing cleaning Q

    It will be a while before I get to this -----

    If I want to clean the inside surfaces of the wings (the spars and the ribs and all that)----
    I am assuming that to do any real job I would have to take the wing completely apart so the parts
    could be cleaned individually--- and the overlap portions could be properly cleaned.

    I know I have a few bent ribs from previous rough handling in storage.... and a LOT of dirty dusty grime
    in there. Once I get the fabric off--- would something like a soap up with diluted Dawn liquid and then a rinse
    and then maybe a pressure wash on a low pressure setting be an OK first step before taking everything apart ?

    Ideally I would like to get everything clean enough to do a complete check for any corrosion and then chromate or epoxy prime every part in there. I expect mostly what I am seeing is just 20 years of dust and dirt buildup while in storage. But on the other hand--- that can also hold moisture and cause surface corrosion. Am I on the right track ?

    One of the previous owners covered them and was about to cover the fuse and tail feathers--- but he got
    cancer and had to back off on the project---- so it just sat and passed through 2 more owners over that
    20 yrs.

    I just don't see how any of that could be cleaned with any completeness without taking it apart.....
    (plus--- Im not that impressed with that guy's work from what I've seen of it so far-- kind of sloppy )

    Just wanted to verify that Im in the right ballpark on my thinking .

    when I removed the fabric on my wings I had enough flies and grime in there to alter the W&B( exaggerating),

    "Once I get the fabric off--- would something like a soap up with diluted Dawn liquid and then a rinse
    and then maybe a pressure wash on a low pressure setting be an OK first step before taking everything apart ?"

    Yep

    a paint brush with a pail of soapy water worked best- Very time consuming-Hours and hoursd-but I didn't break anything and as you are doing the cleaning you are also doing a visual inspection...

    hope this helps

    I use safety solvent, quick and no fear of introducing water into the structure.

    AT----
    Yes-- that's an idea too--- I have never used that --- is it non-flammable I assume ? I do have a nice
    devillebiss wand solvent sprayer that might be good for that ! I think the water would be a concern----

    Of coarse it IS 100 degrees here in the summertime--- Might bake out ok---- but water is NOT aluminum's friend !

    Would you suggest a particular brand of solvent ? Would you try to catch it in a metal floor drip pan and filter and recycle ?

    What I use comes From Parker solvents in fort smith, Safety solvent is all I know, never got the MSDS. Be sure and wear gloves/ventilation use drip pans, it cleans really good and is fairly reasonable. got a rash from it this winter cleaning out a v-35 that was filthy.
