il kick it off with, the best interior vinyl/plastics/dash product ive found to keep in the glove box, is a car plan dash flash shine pad

£2 at asda, ive tried all sorts of stuff, a lot of which doesnt really do a good job and can dull stuff or leave smears etc-particularly on the black vinyl parts of an is interior like the door cards, i use car plan spray cleaner once every now n then,and just use this little pad to shine it up,quick and easy to remove dust etc and shines it up brilliantly, and so cheap and small to keep in the door pod or glove box, give it a go
actualy car plan stuff ive found to be great, the spray can interior valet is good for seats and carpet, and car plan stuff is very cheap at asda, about a third of halfrauds price
