Best way to clean a platter of finger print

June 30th, 2017, 11:15

I tried to clean a finger print from a platter using isopropyl but it leaves residue when evaporated.

How do you guys go about successfully cleaning a platter ?

I don't suggest you try licking it.

Do I need to have an ultra sonic bath to use this or is there some sort of cloth it can be applied to ?

I have made many enquiries into trying to buy Novec from 3M or finding a disti, but no response whatsoever

Will have to work out how to find the English version of that Russian page first.

Another forum is telling me to use Ethanol.

What was the purity of the IPA and was it fresh or had it been used before and sitting around a while? I'd try again using fresh 99.9% IPA and a cleanroom wipe. IPA is very hydroscopic and absorbs moisture from the atmosphere; the water content may be responsible for the smears.

If it's just one fingerprint then I would try to avoid using any chemicals on the platter. You could probably remove the print using a good cleanroom swab (Foamtec, Texwipe). You could use a cleanroom wipe too but be careful, the cheap ones might actually have chemicals on them or they might leave behind microfibers which will end in catastrophic failure. I recommend finger-printing a test drive, cleaning it with the solution you have decided upon, and then test the recovery. If it works, test it again. Once you are happy with your tests then proceed with customer data recovery. Always treat platters as if they are more delicate than you imagine they are, even if you already imagine that they are the most delicate surface :)
