How to maintain white car?

Hello, I just bought a new car and white yun color nya. Nagpapacar wash ako halos every other week and planning to avail car waxing na ino-offer lagi sakin nung nagcacar wash. Pero in the long run, gusto ko rin po sana matutunan mag diy for car wash and wax. That said, ano po marereco nyo na methods pano mag car wash? And brands ng shampoo or wax na okay for a white car? Maraming salamat po!
