"Keeping it clean and Shiny" Keeping it clean is one thing, Keeping it Shiny is what kills it. Any chemical that makes the dash and seats shiny also makes them crack. Burns it up like an ant under a magnify glass.
I haven't been using the Maguires at all ..threw it out as a matter of fact! I have been using warm water and a wee bit of soap, as as friend had suggested.
