Right where do I start ...
Defo go for a Nilfisk one. Much better that the ever popular Karcher. Nilfisk has a metal pump and the Karcher has a plastic pump which was enough for me to buy a Nilfisk
I always pre-wash before I lay a mitt on either of our cars. Helps stops the marring and gets most of the cr@p off the car that would otherwise damage it before washing. I use ValetPro Citrus pre-wash which IMO is better than snow foam (but not as much fun lol). Just make sure you mix the VP CPW with very warm but not hot water for better results.
I dont use the 2 bucket method. I use on large bucket with a grit guard in and always give the mitt a good swirl in the water before each clean stroke. I always use a minimum of 10litres of water to shampoo the car.
Got to be a decent lambswool one (I have 3 various one's lol) IMO. Something like this -http://www.polishedbliss.co.uk/acatalog/flexipads-merino-wool-wash-mitt.html
I've tried about 20-25 different ones and keep coming back to my fave, Wolfs white satin. A litre will give you 50 washes at the correct dilute ratio http://www.polishedbliss.co.uk/acatalog/wolfs-chemicals-auto-shampoo.html
. I have a real 'problem' with MF's in the fact I buy way to many. There are so many out there so difficult to recommend one in particular. There are ones for drying, ones for applying products, ones for buffing … See what I mean
The only thing I would recommend is that you get a decent plush one MF to dry your cars
This is going to cost you plenty enough as it is.
This lot, Tar Remover, Fallout Remover, Wheel Cleaner, Clay and Lube, glass cleaner etc. I would say can wait. You can pick this up as and when its needed.
Personally I dont use waxes at all. I prefer sealants. Just my thing I suppose
Detailing is a very personal thing. What products I like, other dont & visa versa.
Detailing World is an excellent resource and they're all a friendly bunch.
PS Detailing can become very addictive, so beware you bank account may suffer, A LOT lol
