Well finally got hold of some proper car cleaning equipment after a few visits to
@DANBOY66 

So much easier and quicker, not to mention safer on the paintwork
Here's how my car looked after a good covering

And that was after 5 minutes of dwelling, haven't got any final results pics as I was running out of daylight

Current cleaning method is
Rinse car
Snow foam
Agitate with valet pro brush around sills etc
Bilberry my wheels and agitate with wheel woollies
Rinse car
Two bucket method using chemical guys wash n gloss shampoo
Rinse car
Dry car off
Ran out of time and the car was only waxed not long ago so just topped up with some sonax bsd, poor boys on the wheels, Meg's endurance the tires and some Meg's glass cleaner

Comments or advice welcome
