methyl hydrate (lock de-icer) Canajun eh! worked very well for me. A "touch" of mineral oil when done for shine.
Suntan lotion and bug spray on yer hands makes the "factory" coating like glue.
Also the control buttons are kinda like a cell phone as in touch only. Gotta be clean!!
The factory goop just makes it a terrible "cain't do chit" mess!
