Wash twice a week if iam around wax every two
Why do you wax every 2 weeks? What wax are you using? Should last longer than 2 weeks.
Done mine over the weekend, been the first wash since it was painted 2 weeks ago:
Wheels off clean (Bilberry)
Serviced the brakes
Painted hubs
Arches cleaned (G101) and sealed (fkp1000)
AF snowfoam
Wash
IronX
Tardis
Clayed
Snow foam again
Wash
Dried
Polished DA(AF revitalised 1,2 and 3) various pads
Sealed (Prima Amigo 3m blue pad)
Zaino Z1 (2 coats so far)
Trim dressed (AF Revive)
Tyres dresses (Megs)
Interior (AF Spritz)
Hoover
I tend to do this every 4 months. I'm still learning and that is by no means perfect but it is something I enjoy so don't class it as obsessive compulsive ( a little sad according to people at work, but they still ask me to clean theirs)
OP I would avoid T-Cut. My wife has a black VW Up! and I tend to clean that aswell. I would suggest Prima Amigo for a sealant (Works so well on black paint and will fill some of the swirls) and just try to improve your cleaning technique to attempt to reduced the chance of causing damage, two bucket wash, snowfoam, pat dry with a decent mf towel. It can be done without spending big bucks.
