I’m starting to get into the detailing a bit more and have previously machine polished the bus, but thought I’d post up the process that I use for a general clean:
First off I clean the wheels and use GTechniq Iron Fallout remover - despite your wheels looking clean, the fallout will breakdown the iron that has stuck on your wheel which you can’t see and will look like this:


I then use Bilt Hamber Snow Foam connected to my pressure washer - this breaks down all the dirt and grime:


Once jet washed off I then use a mixture of Meguiars wash/wax & Auto Glym Shampoo - I use a Chemical Guys wash mitt & always use the two bucket method (to wash & rinse):


I usually go round the van twice and then rinse off:


Once completed I used Auto Glym Vinyl & Rubber Care for around the window seals and a Sonic Brush to remove the moss and dirt:




I use a 600gsm microfibre to dry the paint work and on this occasion used Pete’s 53 wax as it brings out a glossy shine on darker paint - it’s a straight wipe on wipe off as you don’t need to wait for it to cure - apply to a panel at a time:




I then used Sonax wheel sealant for the wheels and the Meguiars tyre gel:



For the metal bumpers I use good old WD40 & Black To The Future cream on the surrounds:




Then spray Chemical Guys protectant for the arches:


I then use a final detailer just to remove any remnants of the wax:






I normally use a final sealant after waxing but I only applied that a couple of months ago and it smells bloody awful, so will re-apply next time.
I’m also looking on testing a Sio2 spray sealant to see what results this achieves - more details here if you’re interested:
