Clay Bar Treatment Checklist

Most car owners make this harder than it needs to be. Here's the straightforward approach that actually works—no fluff, no upselling.

If your paint feels rough like sandpaper even after a wash, you've got bonded contaminants. This checklist covers how to safely clay your car to get that glass-smooth finish back without marring the paint.

Clay Bar Treatment Checklist

Aussie Conditions

Australian conditions are tougher than most—intense UV, red dust, coastal salt, and 40°C summers. European car care advice often doesn't cut it here.
Quick Summary

Look, I've seen too many blokes wreck their clear coat by jumping straight into a polish without claying first. After 15 years in the trade, I reckon claying is the most satisfying step in detailing, but you've gotta do it right. This is my personal checklist for getting rid of that nasty red dust and coastal salt spray that cakes onto our cars here in Oz. Give it a crack on a Saturday arvo and your paint will thank you.

01

The Gear You'll Need

What You'll Need

0/8
Clay Bar (100g-200g) — Get a 'Fine' or 'Medium' grade. I'm a big fan of the Bowden's Own Fine Clay Bar for most Aussie daily drivers.
Dedicated Clay Lubricant — Don't use dish soap. Use something like Meguiar's Quik Detailer or a proper clay lube to prevent scratching.
Microfibre Towels (3-4) — Clean, high-gsm towels. You'll need them to wipe away the lube residue as you go.
Iron Remover Spray — Optional but recommended for wheels and lower panels to dissolve metal particles first.
Bucket of Warm Water — Keeps the clay soft. I learned this the hard way on a cold morning in Melbourne, rock hard clay scratches paint.
Cutting Tool or Scissors — To cut your clay bar into smaller, manageable pieces.
Stool or Creeper Seat — Your back will thank me later, especially when you're doing the lower doors and bumpers.
Wax or Sealant — Claying strips protection, so you'll need to re-apply your wax or ceramic topper after.
02

Pre-Start Checklist

What You'll Need

0/4
The 'Baggage Test' — Put your hand in a plastic sandwich bag and rub it over the clean paint. If it feels bumpy, you definitely need to clay.
Shade Check — Is the car out of the sun? Never clay a hot panel in 40 degree heat; the lube will flash off instantly.
Deep Wash Complete — The car must be 100% clean. If you leave dirt on there, you're just rubbing grit into your clear coat.
Clay Condition — Ensure your clay is fresh. If you've dropped it on the garage floor, chuck it in the bin. No exceptions.

Step-By-Step Execution

Tap each step to mark complete
01

Knead the Clay

Cut a 30g piece of clay and flatten it into a patty. Keep it warm in your hands or that warm water bucket so it stays pliable.

02

Lube the Panel

Spray a 30x30cm area generously with lubricant. Truth be told, you can't really use too much lube here, but you can definitely use too little.

03

Light Pressure Slides

Glide the clay back and forth in straight lines. Don't press hard. You'll hear it 'grabbing' at first, then it'll start sliding silently once the contaminants are gone.

04

Check and Fold

After every section, look at the clay. If it's brown or grey from outback dust, fold it over to a fresh, clean side and flatten it again.

05

Wipe Clean

Use a fresh microfibre to buff away the leftover lubricant before it dries. Move to the next section and repeat until the whole car is smooth.

04

Final Inspection

What You'll Need

0/3
The 'Touch Test' — Run your fingers over the roof and bonnet. It should feel like glass. Any rough spots? Hit 'em again.
Check for Marring — Look for light hazing. If you used a medium clay, you might need a quick light polish to restore the gloss.
Seal the Deal — Apply your protection. I once forgot this on the missus' car and the sap stuck twice as hard the following week. Don't skip it.

Watch Out

If you drop your clay on the ground, even for a split second, throw it away. I've seen a mate try to 'pick the dirt out' and he ended up swirling his black Commodore so bad it needed a multi-stage correction. Also, stay away from matte wraps or matte paint with a traditional clay bar, you'll ruin the finish.
