In Phoenix, Las Vegas, Dallas or Miami, your car spends a lot of time under intense sun. Heat and UV exposure take a toll on paint, black plastic trim, rubber seals and dashboards – and desert dust adds a fine abrasive layer on top. You can't change the weather, but a simple routine goes a long way.
What sun and heat do to your car
- Paint: unprotected clear coat can lose gloss over time, and contaminants like bird droppings and bug splatter bake on faster in the heat.
- Plastic and rubber trim: unprotected black trim can fade and look chalky.
- Interior: dashboards and seats get hot and can dry out and fade.
- Dust: in the Southwest, fine dust settles daily. Wiping it off dry is a fast way to add swirl marks.
A sun-protection routine that works
- Wash early or late. Never wash on hot paint at midday – water and soap dry into spots almost instantly. Early morning or evening in the shade is best.
- Remove bird droppings and bugs quickly. Soften them with plenty of moisture and lift gently – don't scrape them dry.
- Seal the paint. A ceramic spray like 7WASH Hydro Slick adds a slick, protective layer that makes contaminants easier to remove. See ceramic spray vs. wax.
- Protect trim. 7WASH 3D Protector cares for plastic, rubber and vinyl inside and out and helps protect against UV and drying out.
- Handle dust the right way. For light dust, use 7WASH Wash & Wax Waterless with a clean microfiber cloth – lubricated wiping instead of dry dusting. For heavy dust or sand after a storm, rinse with water first.
Protect the interior too
- Use a windshield sunshade every time you park outdoors.
- Park in a garage, carport or shade whenever you can.
- Wipe the dashboard with 7WASH Interior Cleaner and treat vinyl and plastic with 3D Protector.
- Clean the inside of the windshield regularly with 7WASH Glass Cleaner – a hazy film makes glare much worse.
Water-wise washing in dry states
Many Western states and cities have water-use rules, and some get stricter during drought. California, for example, prohibits washing a vehicle with a hose unless it has a shut-off nozzle. A waterless wash for light dust between regular washes is an easy way to use less water – check your local rules for washing at home.
FAQ
How often should I apply a sealant in hot climates?
Follow the product label and watch the beading. When water stops beading tightly, it's time to reapply.
Is it OK to dust my car with a dry cloth?
It's better not to. Dry dust is abrasive. Use a waterless wash spray for lubrication, or rinse with water first.
Can I wash my car in the afternoon sun?
Avoid it. Hot panels dry soap and water into spots. Early morning or evening in the shade is ideal.
Always read the label and safety information on each product page before use.
