It's me again! So I started working on my Ty!

Yesterday I removed the old radio, the head and the puplit...and now I'd like to clean mast and service the winches!
Any suggestions?
For the mast, I was told to use acetone, does it make sense?? For the GIBB ENGLAND winches, no idea yet!
I saw the other posts but..is there a good youtube video?!?!?

Thanks!
