For me currently it's:
Nilfisk power washer; Autobrite Snow Foam cannons
Autoglym (AG) Polar Blast Snow foam
AG Polar Wash or Ultimate Shampoo
AG Polar Seal or Chemical Guys 'Insta Wax' - this is more of a spring/summer finish, Polar Seal over the Autumn & Winter months
I use either a decent microfibre towel or a lambs wool mitt to wash the car; 2 buckets usually, but always have a grit guard in any bucket I use
The car gets towel dried with The Chemical Guys 'Woolly Mammoth' towel and the alloys/tyres dried with a normal drying towel (such as one of the Megs one or standard ones from Amazon)
I use AG Magma to clean the wheels and de-iron/tar the lower quarters of the cars; AG Tar Remover for the stubborn spots (silver cars, so it stands out a mile)
The alloys get cleaned with the Chemical Guys Red Rocket wheel brush and whichever soap I'm using; they'll get removed every other month for a full clean and wax; the wheel arches cleaned/scrubbed with a stiff brush and then treated with AG Rubber & Vinyl Care (works well IMO)
The interiors are simply hoovered; surfaces treated with AG Rubber/Vinyl care and a microfibre towel. All door seals are treated with Gummi Pflege regularly:

Engine bays get power washed, dried and treated with AG Rubber/Vinyl care again; works well and lasts well
As for the glass; that gets treated with wither Dodo Juice 'Clearly Menthol' or AGs 'Fast Glass'
That's about it really; I'm not a detailer, so I don't do DA polishing etc. I do have an orbital polisher, but rarely use it as don't trust myself and our cars are silver, so they hide any marks very well
