Keeping Your White Paint From Turning Yellow: The Pro Detailing Routine (Mar 2026)

Never wash a white car in the direct sun if it's 30 degrees out. The chemicals will dry too fast and leave streaks that are a nightmare to get off. If you have to do it outside, wait until the arvo when the sun's lower.

Give the whole thing a massive blast with the pressure washer. You want to get all that loose red dust and salt off before you even touch the paint with a mitt.

Always do your wheels first. If you wash the body then the wheels, the brake dust spray will just land back on your clean white panels. Trust me, I learned that the hard way on a black Commodore, never again.

If you've got a foam cannon, use it. Let it sit for 5 minutes to dwell. It breaks down the bird muck and bat droppings without you having to scrub.

One bucket with soapy water, one with clean water to rinse your mitt. Go from the top down. Roof first, then bonnet, then the sides.

This is where white cars come alive. Spray an Iron Remover over the dry-ish paint. On white, you'll see it 'bleed' purple. That's the chemical reacting with metal particles from brakes and industrial fallout. Leave it for 3-5 mins, but don't let it dry!

Blast all that purple 'blood' off. You'll already notice the white looks 'purer' and less yellow.

If the paint feels like sandpaper when you run your hand over it (use a plastic sandwich bag over your hand to feel it better), you need to clay it. Use plenty of lubricant or soapy water and glide the clay over the surface until it's smooth as glass.

Rinse off the clay residue. Use your big microfibre drying towel. Pat it dry rather than dragging it if you want to be extra careful.

Check the door sills and around the badges. White cars love to hide gunk in the gaps. Use a soft brush if you need to get in there.

Apply your sealant or wax. Since it's Autumn and the UV is still mental, I reckon a ceramic-based sealant is better than a traditional carnauba wax. Wax melts at high temps; sealants don't.

White paint looks rubbish if the black plastic trim is faded and grey. Hit it with a trim restorer to get that sharp contrast.

Clean the glass with a dedicated cleaner. Chuck some tyre shine on, but don't go overboard, nobody likes tyre sling down the side of their fresh white doors.
