I've got this big deck cushion covered in vinyl, and it's white with dark blue stripes. It's not that old but has been left out quite a bit, and I've cleaned it up and the white parts have come up very well almost as new, but the dark blue areas have this sticky feel and remain grubby and a bit gooey even though I've scrubbed it with good quality vinyl cleaner.
Has anyone else come across this phenomena. Would it have something to do with the dark coloured areas reacting to the elements where the white does not?
I think I will need a tougher cleaner for the blue parts, any recommendations of a brand that won't discolour the blue?
