Keeping Your Interior From Melting This Summer (Feb 2026)

Stop using those cheap, greasy 'protectants' from the servo that make your dash look like a mirror. They actually attract dust and can even accelerate cracking under intense UV. I always tell my customers to use something like Bowden’s Own Vinyl Care or Aerospace 303. They leave a factory matte finish and actually have proper UV blockers. I learned this the hard way when a customer's windscreen kept fogging up from the 'off-gassing' of a cheap greasy spray I used back in my rookie days.

It sounds basic, but a high-quality, thick sunshade is the single best thing you can do. It drops the cabin temp by 10-15 degrees easily. If you've got leather seats, it stops them from getting hot enough to cook an egg on, too. (The missus will definitely thank you for that one). Don't buy the $5 flimsy ones; get the custom-fit ones that actually cover the edges of the glass.

Leather is skin, right? In this heat, it dries out and shrinks, which leads to those nasty cracks on the bolsters. I give my seats a quick wipe with a dedicated conditioner every few weeks in summer. I'm a big fan of Gtechniq L1 Leather Guard because it adds a bit of moisture but also stops your jeans from staining the leather if you're a bit sweaty after a day out.

If you're parked in a safe spot, leave the windows down about 1-2cm. It stops the 'oven effect' where heat builds up and starts melting the adhesives in your roof lining. I once had a client with a beautiful Euro hatch where the headliner just sagged overnight because the heat was trapped inside during a week of 42 degree days in Perth. No dramas if you've got weather shields, too, keeps the rain out if a summer storm rolls in.
