Replying to Un-sticking rails.

i searchbarred and found a few topics, but none really helped.

the past few days the rails at my mountain have been sticky as fuck. the boxes are fine for the most part, but all of the metal rails are just super sticky and hard to slide.

what can i do to make them slide better? rub snow on them? wax? water? like three days ago they were fast as fuck.

i know they get sticky in warm weather sometime, but lately its been between 0-10 degrees. i think it got up to like 23 today. (this is all Fahrenheit)
