Once every 4-6 weeks. We live in a condo so I have to take it to the DIY car wash place to do a 2 bucket myself (I worked a deal out with the owner and paying him 10 bucks at time during their quiet hours). No rain and no snow here. The only thing I deal with is dust in the garage which I can use a duster on, I’ve had my tire dressing last 3months (Carpro Perl) and I’ve never even had rust accumulation or even seen it on the brake rotors.
