what can i use to wash my car at home

Ah, the classic DIY car wash conundrum. First off, skip dish soap—it's a sneaky paint stripper. Instead, grab a proper car shampoo; these are specially formulated to be gentle on your paintwork and wax. Use a soft sponge or a microfiber mitt to avoid those pesky swirl marks. Rinse with a hose or buckets of water, and for a final flourish, dry with a plush microfiber towel to dodge water spots. If you want to get fancy, consider a quick detailer spray to boost shine and protection.
