Apparently white vinegar works for aluminium:
I too have ben working with some laser print transfer materials. I used to use standard HP printer with standard HP color cadridge and no paper would work with it. However brand print trancparency film worked fine, but need a clothes iron to transfer image. Standard laminator just does not have enough heat, I read from several sources that you need 180C to fuse the dye.
I still have the same old lasr printer and bought a new color cadridge, not HP and not the cheapes one, but mid priced generic. Transparency film does not work any more, but fun fact is that super glossy and coated paper works almost fine with a the same laminator.
I got some chinese yellow transfer paper and it seems to work most of the time ok. Not great for surface mout but ok with trough hole system.
I am thinkking of getting a 100€ T-shirt picture transfer press for this purpose, they should provide enough heat and pressure to get work done....or try UV option again...or try gardening instead.
