What You'll Learn
Aussie Conditions
Look, we all know black cars look the best for about five minutes after a wash, but they're a nightmare to keep right. If you've got a black rig, you're dealing with heat soak, visible dust, and every tiny scratch showing up like a sore thumb. I've put together everything I've learned from 15 years of chasing that mirror finish so you can keep your car looking mint without losing your mind.
The Love-Hate Relationship with Black Paint
The Gear You Actually Need
What You'll Need
While you're here...
Preparation: Setting the Stage
Find the Shade
Never, ever wash a black car in direct sunlight. The water will spot and the soap will dry before you can say 'no dramas'. If you haven't got a carport, do it at 7am or late in the arvo.
Wheel First Approach
Clean the wheels first. If you wash the body then the wheels, the water on the paint dries and leaves spots while you're scrubbing the rims.
The Cold Water Test
Touch the panels. If they're hot, hose them down with cool water for 5 minutes. We need to drop the surface temp so chemicals don't flash off.
Inspection
Walk around with a torch. Look for bird droppings or bat prep, these are acidic and need extra care so you don't scratch the paint while removing them.
Setup your Buckets
Fill your wash bucket and your rinse bucket. Chuck your wash mitts in to soak so the fibers are nice and soft.
The Safe-Wash and Polish Procedure
Heavy Rinse
Blast off as much loose grit as possible. Focus on the wheel arches and lower sills where the road grime hides.
Snow Foam Pre-Wash
Cover the car in a thick layer of foam. Let it dwell for 5 minutes (don't let it dry!). This softens the dirt so it slides off without scrubbing.
The Two-Bucket Wash
Wash one panel at a time using very light pressure. After each panel, rinse the mitt in the plain water bucket, then dunk in the soapy one. Start from the roof and work down.
Chemical Decon
Spray your iron remover on the dry-ish paint. On black, you won't see it turn purple easily, so give it 3 minutes then rinse thoroughly.
Mechanical Decon (Clay)
Use plenty of lubricant. If you're using a clay bar, keep folding it. If you're using a mitt, rinse it constantly. This gets the 'grit' out of the paint.
The 'Pat' Dry
Lay your large drying towel flat across the bonnet and pull it towards you. Don't scrub. Use a leaf blower for the mirrors and badges if you've got one.
Tape it Up
Use blue painter's tape on plastic trims and rubber seals. Trust me, getting white polish residue off black plastic is a nightmare you don't want.
Test Spot
Don't polish the whole car yet. Do a 30x30cm square on the boot or bonnet. See if your polish is actually removing the swirls.
Machine Polishing
Work in small sections. Use 4-5 drops of polish, spread it on speed 1, then bump it up to speed 4. Slow, overlapping passes are the secret.
Wipe and Check
Use a fresh microfiber and your IPA spray to remove the polish oils. Check with your light. If it's clear, move to the next section.
The Final Wipe
Once the whole car is polished, give it a final wipe with a clean, plush towel to ensure no dust is left.
Apply Protection
Apply your sealant or wax. On black, I reckon two thin coats are better than one thick one. It adds that extra 'pop'.
