Autoglym is still good, when I bought my car, the dealer gave it a thorough cleaning and a protective coat over the paint, and I got a full Autoglym bag with all of the various sprays in, some I’ve never used, like the tyre and bumper stuff, but I use the wash, the spray wax, and the interior cleaners, including the upholstery – there were some stains from the previous owners, it was a Motability car, so not unusual. A couple of goes with the upholstery cleaner, followed by a scrub with a nail brush, then gone over with a damp microfibre cloth, and it’s peachy.
I’m going to have to replace the wax polish soon, that’s got fairly low now.
