A tip which you may find useful..... The cab floor of my Fiat Ducato (that is not covered by carpet) which was looking a bit dull and lifeless is now looking like new. I have in the past used 'back to black' silicone spray, but this, whilst looking good, has made the floor slick and slippery. I bought a can of 'tyre shine' from the Pound shop yesterday, and today have given the interior rubber a good coating..... spray on a goodly quantity, and then wipe of with a rag. The mats now look like new, with a dull sheen, which isn't at all slippery. Money well spent!!
