Can't go far wrong with a bucket of suds and a damp cloth.
I caught the Vx valet chappie molesting cars on the forecourt and asked him what he used to shine up the bonnet emblem ('cos it's blotchy grey). That was a language barrier problem for starters because I think he's Polish (so we shout very loud and slowly, in English) but finally worked out he uses cockpit spray, but I find that makes the genuine dash plastic all sticky. So don't use cockpit spray on the bonnet emblem, 'cos it makes the black bits go blotchy, use AG bumper and rubber ...
Let's see: saddle soap gets white paint off black leather car seats and Turtle Wax "Platinum Series Essential Leather Cleaner & Conditioner" (phew) brings them up all nice again.
The spray can of 'Scotts Upholstery Cleaner' that Vx give you in the paint protection kit removes diesel from carpet (yuk!)
I'm not one for scrubbing the interior much but the littlest Dyson Animal actually sucks crud out of the carpets and seats. Whereas other portable vacs, don't.
Meguiar's "Quik Detailer" (sic) is useful everywhere as is AG Fast Glass spray (much the same stuff): no residue smears.
The A/C clears window mist PDQ but a couple of 1kg bags of ThoMar 'Air Dry' reusable desiccant seems to be absorbing November's dampness and stopping it happening in the first place. A rather large damp doggie doesn't help much either.
Scrubbing the inside of the screen with AG "Glass Polish" seems to stop condensation forming and streaking to a large extent. That gets done every few weeks through winter so I can see out properly.
