So quite low temperature hot air will melt it but how to remove what remains
after allowing most to drip away? tissue paper as capillary mop? or a
chemical ? . I don't know if it is a reaction with the ink on the device
markings but the wax residue/oil makes it very difficult to read even under
x30 microscope barrrel and various angles of light. Any ideas on how to
increase the contrast/readability?
