I use a microfiber mitt to clean the car.

I only clean a small section at a time. I hose the dirt off the mitt BEFORE putting it back in the bucket.

Also, wipe the sides of the car vertically in straight lines. Wipe the hood/trunk the way the wind blows (also in straight lines). The goal is to avoid putting micro-scratches in the car. Do not wipe in circles!

My basalt black car has almost no scratches (no spiderwebs) - it looks almost "candy apple". Some of that is because I use clay and polish (different thread). But it's also because I wash my car correctly.

LAST COMMENT - Don't use dish detergent. Dish detergent removes your wax/sealant. Use a quality car wash product that is designed to not remove your wax/sealant.
