just a few days ago someone on our local mailing list reported excellent
results cleaning his traps with 10% sulphur acid.
The acid does not corrode the aluminum any further,
but cleans out all the dirt.
probably the aluminum oxide layer gets a bit thicker but
that is its natural anti-corrosion-jacket anyway.
The traps were reported to function very well afterwards
