Park in the shade. It is the easiest form of protection. By avoiding direct sunlight, you’ll help keep your dash from drying and cracking. If it is safe to do so, open the windows a crack to help lower the interior temperature and equalize the air pressure.
Use a windshield sun protector. It’s a great way to keep your car cool and prevent sun damage. They may look a little cumbersome at first, but they are really quite easy to use.
Wipe dash with a microfiber cloth. Dust and dirt can cause tiny scratches that can become worse over time. Wipe down the dash frequently to remove all particles. A low-gloss detailing product will also protect it and reduce glare.
Install seat covers. They not only protect leather and fabric seats, but they also help keep them cool.
Protect leather seats with a conditioner. The sun and heat can really do a number on them. To help avoid cracks or tears, keep seats clean, and apply leather conditioner often.
Tips for the exterior
Wash and dry often. Sun and heat can fade and crack the paint. Frequent washing and hand drying help remove dirt and dust particles that can cause micro scratches and dull your car’s finish.
Wax your car. A layer of wax between your car’s finish and the sun’s ultraviolet rays is a great way to help protect it. How often a car needs a wax job varies, but it is best to do it on a regular basis.
Check tire pressure. Hot pavement and underinflated tires can be a dangerous combination, and may lead to a blowout. Even good tires can lose about one pound of air pressure a month, so it’s really important to check often when it’s hot. Make sure you follow your vehicle’s manufacturer recommended tire pressure.
