Best thing is to go for Meguairs or Autoglym products
Avoid Turtle wax Color Magic as it contains T-cut
Clean using soft mittens rather than a sponge
Use the 2 bucket technique
Never use a commercial carwash
Never use a Jetwash on the paintwork
Hose down after washing and before the chamois leather
Always polish and then wax.
Only use the claybar after the chamois and never leave the car between the two for longer than you need as dust will soon resettle on the car and then using the claybar is a no-no. I claybar 3 times a year.
There is a lot more if you are really into car care, but the above is a good measure to keep your car pristine and swirl free.
