Keeping Your Dash From Cracking in the Aussie Sun

Your paint is under constant attack: UV rays, bird droppings, tree sap, and road grime. Protection isn't optional—it's essential.

Don't let the February heat turn your dashboard into a dried-out mess. Here is exactly what you need to clean and protect your interior vinyl from UV damage and red dust.

Keeping Your Dash From Cracking in the Aussie Sun

Aussie Conditions

Our intense UV breaks down waxes faster than overseas. Ceramic coatings last longer, but even they need topped up more frequently here.
Quick Summary

Look, if you're living anywhere between Perth and Sydney right now, the sun is absolutely punishing. I've seen way too many modern dashboards start to go sticky or crack because they've been baked at 45 degrees without any protection. This checklist is for anyone who wants to stop that 'melted' look before it happens. It's quick, easy, and will save you a fortune in replacements down the track.

01

The Gear You'll Actually Need

What You'll Need

0/8
Dedicated Interior Cleaner — Something like Bowden's Own Naked Glass or a mild APC. Don't use soapy dishwater.
UV Protectant (Non-Greasy) — Aerospace 303 is my go-to. Avoid the cheap, shiny stuff at the servo, it acts like a magnifying glass for the sun.
3-4 Microfibre Cloths — Make sure they're clean. Red dust from your last trip will scratch the plastic if it's still in the rag.
Soft Detailing Brush — A cheap makeup brush from the missus works a treat for getting dust out of vents.
Magic Eraser (Use with caution) — Only for stubborn scuffs on lower door plastics. Never use these on the actual dash or screens.
Glass Cleaner — For the inside of the windscreen once you're done. Overspray happens to the best of us.
Vacuum with Brush Attachment — To suck the loose grit out of the cracks before you start wiping.
A decent sunshade — The best protection is keeping the sun off it in the first place.

Pre-Start Checklist

What You'll Need

0/4
Park in the shade — I learned this the hard way on a black Commodore. If the dash is hot, the product just bakes on and streaks.
Check for 'Sticky Dash Syndrome' — Common in some Toyotas and Mazdas. If it's already melting, stop and see a pro.
Empty the clutter — Chuck the coins, receipts, and old Maccas bags in the bin so you have a clear run.
Test a small spot — Always try your cleaner on a hidden bit of trim first. Better safe than sorry.

Step-By-Step Protection

Tap each step to mark complete
01

Dry Dust Everything

Use your brush and vacuum to get the loose Aussie dust out of the vents and seams. If you add liquid now, you'll just make mud.

02

Clean the Surface

Spray your cleaner *onto the cloth*, not the dash. This stops you getting gunk inside your electronics and switches. Wipe it down thoroughly.

03

Agitate Stubborn Spots

For high-traffic areas like door handles or armrests, use the brush to work the cleaner in. A customer once brought in a Hilux caked in red dust, this was the only way to get it out.

04

Apply UV Protectant

Again, spray onto a fresh microfibre. Apply a thin, even layer across all vinyl surfaces. It's like sunscreen for your car.

05

The Final Buff

Wait about 2-5 minutes, then take a dry side of your towel and buff the surface. This removes any excess and leaves a factory-fresh matte finish.

06

Clean the Glass

Finish by cleaning the inside of the windscreen. Protectants often leave a bit of 'fog' on the glass that's a nightmare to see through at night.

04

Final Inspection

What You'll Need

0/3
Check for streaks — Look at the dash from the passenger side angle. Sometimes you miss a bit.
Toggle the vents — Make sure they still move freely and aren't gummed up with product.
Check the steering wheel — Ensure it isn't slippery. Nothing worse than a greasy wheel when you're trying to park.

Watch Out

Avoid silicone-based 'high gloss' sprays like the plague. They look cheap, reflect into the windscreen on sunny days, and actually dry out the vinyl over time. Also, never spray cleaners directly onto the instrument cluster, those clear plastics scratch if you even look at them funny.

Detailer's Secret

If you've been out west and the red dust is everywhere, use a bit of compressed air (or a hairdryer on cold) to blow out the seams around the radio before you start. It saves you ages in wiping.
