How do I keep my car clean?
Weekly: remove trash and quick vacuum. Every two to four weeks: wash in the shade with car soap and microfiber. Every few months: wax or sealant and deeper interior clean.
Use products made for cars, not household cleaners.
Keeping the interior clean
- Remove trash and loose items weekly.
- Vacuum seats, mats and carpets, and use a crevice tool.
- Wipe hard surfaces with a damp microfiber and a mild interior cleaner.
- Clean glass with a cleaner that is safe for tinted windows (avoid ammonia on tint).
- Use all-weather mats, and shake them out regularly.
Washing the exterior safely
- Park in the shade and let the paint cool.
- Rinse off loose dirt first.
- Wash with car shampoo (not dish soap) and a clean wash mitt, working top to bottom.
- Rinse, then dry with microfiber to avoid water spots.
- Apply wax or sealant every few months for protection.
