Cleaning you would only need to use some degreaser.Not too strong and then wash it with soapy water.No don't use armour-all as it has oil in it and in the sun the oil dries the plastic out.You could use 303 (I think it's called) Supabarn has it or Autopro (If you go to auto pro you'd have to ask a sales guy.As they don't have it on their shelf.Don't know why they just don't).303 is the same as Armour-all but without the oil mixed in.So it protects better and does a great job.
