How to clean plastic slide ready for selling?

just that really is their a product which is good at removing general muddy marks etc? I've done it before with warm soapy water but didn't know if there was a particular product that would bring it up well.

A good going over with a pressure washer usually does the trick. Are you able to borrow one off someone?

thean, thanks for that, we actually have a pressure washer I just hadn't thought to use it!!
