Can you use this on a micro usb port?

It's a physical electrical connection between two small conductors. I would say yes, and would try it myself. If I understand your question the "male" & "female" parts of this connection are self sealed by the housings that contain them, so there would be no contamination of any other parts/connections by the use of CRC. I assume (almost always big trouble) you have an intermittent connection at this USB? Before you spend any $$. Be certain its a contaminated connection, and not a broken/loose wire in either side. Test the "male" in a known good "female" and if the bad connection is absent then try a know good "male" in your suspected bad "female" and see if you can isolate the specific issue. Troubleshooting the component by isolating them one by one is a tried & true method to isolate electrical issues.Either way CRC is a good product, W/many electrical connection uses, potentiometers, switches, slider controls, fuse blocks - almost endless. Good luck.

How would you compare CRC electronics cleaning products with their Deoxit counterparts? I have only used CRC non-electrical automotive cleaners.

I use both. There is little to no difference other than the price and size of the cans.

How long does it take to dry?

Nearly instantly at 70deg F. I'd say under 20 seconds, generally.

Does this can come with a straw nozzle for spraying into tiny crevices? Thank you.

Yes it does. It should be taped to the side of the can
