i am cleaning dust
and about the compositions it says : Aqua and Alcohol
Aqua i think is water according to cosmetic companies.
Alcohol type should be specified.
Over here rubbing alcohol uses isopropyl alcohol at 40 % as a denaturant.
Its not very nice for dust ime it evaporates slowly and sludges the dust making it difficult to vacuum.
Cleaning dust off psu's especially hv ones can be very annoying.
Not allowed to use compressed air as it blows it all over the place just a hoover.
industrial meths (brushed with adequate ventilation) used to be my preferred solution.
Cant have water in it.
Someone suggested colemans fluid but iv never been sure about that to try it.
edit
to be clear i was using pure isopropyl not rubbing alcohol.
