The window seals on the car have not aged well, in addition to that, the boot seal was always terrible. As a kid I washed the car for my dad once and the entire boot got soaked when I was a little too enthusiastic with the pressure washer.
Given that, and the drivers side window being stuck down, it had to be a waterless wash to get the dirt and dust off, letting me get a look at how the paint is underneath.
Bit of YouTube research and I was good to go, the detailer’s favourite: quick detailer spray and a micro fibre towel (or two)
The dirt was proper stuck to the paint, hence I went a bit heavy with the QD spray but it all came off quite well in the end. Used 1 microfibre for the dirt removal, folding regularly to minimise the amount of dirt getting wiped over the paint. Then used a second microfibre to buff off the residue and clear out some of the more fiddly bits.
I appear to have entirely skipped pictures during the process since I was mucking about videoing it.
Also have the glass a going over with glass cleaner on a jay cloth then buffed with another microfibre.
Here’s the video of the process/stages:
