Sometimes my rear disc brake squeaks, not all the time, it happens when it's clean and dry and also after some mud gets on it and then dries out. What can I do to fix this squeaking?

Try taking your pads out and smearing a bit of copper grease on the back of the pads (NOT the braking surface obviously... :roll: ) before putting them back in.
This is done as a matter of course when fitting new pads to a car or motorbike for the precise purpose of preventing them from squealing.
I used Finish Line degreaser :!: , it did affect performance at first, if felt like I was breaking them in, but they no longer squeak when wet and they no longer grind when dry.

Exactly, although knowing why they are squealing is a good idea, as well. This is caused because the pad and the plate it is attached to are vibrating. Any type of goo or smear-able suppressor will stop this activity. As Dave said, "the precise purpose." When pads have nothing to restrict their squeaky movement (vibration,) they ride free without any damping, causing them to resonate, which is heard as a squeak.
take out the pads and rub the braking surface with a bit of kitchen roll then carefully rub it with fine 'wet and dry' paper. Repeat until the kitchen roll only shows a little pad dust, no other manky stuff.
Use some form of brake disc cleaner. I've always used isopropyl alcohol as I had a bottle of it for cleaning CD's (not sure if it should be used for CD's to be honest! or disc brakes! but it does get rid of grease / oil).
Un-clean rotors and pads seem to be the main culprits

Some motorcycle disc brakes were known for their squeaks !

like the pads on the left and right
you could also make some anti squeel shims out of thin metal sheet
