Monthly Deep Clean: Beat the Heat & Salt Checklist

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

It's February in Australia, and the sun is trying to cook your paint while the salt air eats your trim. This checklist covers the deep clean you need to do once a month to keep your ride from looking like a sun-bleached desert relic.

Monthly Deep Clean: Beat the Heat & Salt Checklist

Aussie Conditions

Living near the coast? Salt air corrodes metal and degrades rubber seals. A fortnightly wash underneath is essential, not optional.
Quick Summary

Look, Feb is the brutal part of summer. Between the 40-degree days and the bat droppings that'll etch your clear coat in five minutes flat, you can't just 'she'll be right' your car care. This is the routine I use for my mobile clients to keep their paint healthy during the heatwaves.

01

A Note from the Garage

I once saw a white Hilux that had been parked under a gum tree for two weeks in February. The sap and bat juice literally baked into the paint, cost the bloke a fortune in correction. Honestly, don't be that guy. Spend a couple of hours this weekend and save yourself the headache later.

The Gear You'll Need

What You'll Need

0/8
Two 15L Buckets with Grit Guards — Essential. One for soapy water, one for rinsing your mitt.
Quality pH Neutral Wash — Bowden's Own Nanolicious is my go-to for summer.
Soft Microfiber Wash Mitt — Don't use a sponge, they're paint killers.
Iron Decontamination Spray — I reckon Gtechniq W6 is the best for coastal salt and brake dust.
Bug & Tar Remover — Crucial for those dried-on grasshoppers after a highway run.
UV-Rated Trim Protectant — Something like Aerospace 303 to stop your plastics turning grey.
Dedicated Wheel Brush — Long-handle one for the inner barrels.
Big Drying Towel — The twisted loop ones are heaps better than a chamois.
03

Pre-Start Checklist (Before You Wet the Car)

What You'll Need

0/5
Check paint temp — If the bonnet is hot enough to fry an egg, stop. Wait for shade.
Clear out the loose rubbish — Chuck those old servo receipts and Maccas bags first.
Inspect for bat/bird droppings — Spot-clean these with a quick detailer before the main wash.
Roll up all windows — Sounds obvious, but I've soaked a few interiors in my time (oops).
Check your hose connections — Nothing worse than a leak killing your water pressure mid-rinse.

Step-By-Step Deep Clean

Tap each step to mark complete
01

Cool Down & Wheels

Rinse the wheels first. Use your iron remover and brush to get that baked-on dust off before you touch the paint.

02

The Pre-Rinse

Blast as much red dust and salt off as possible. Don't start rubbing until the loose grit is gone, or you'll scratch it.

03

Bug Removal

Spray bug remover on the front bar and mirrors. Let it sit for 2 mins (don't let it dry!) then rinse it away.

04

Contact Wash

Two-bucket method. Start from the roof and work down. Rinse your mitt in the clean water bucket after every panel.

05

Final Rinse & Dry

Give it a thorough rinse, especially in door jambs. Dry it fast with your microfiber towel to avoid nasty water spots.

06

UV Protection

Apply a sealant or wax. In this heat, I reckon a ceramic-based spray sealant like Meguiar's Hybrid Ceramic is the easiest win.

07

Interior Wipe Down

Wipe the dash and door cards with a damp cloth, then apply UV protectant to stop the Aussie sun from cracking the vinyl.

05

Final Inspection Checklist

What You'll Need

0/4
Glass check — Clean the inside and out. No smudges allowed.
Tyre shine — Don't go overboard, you don't want it flinging down the side of the car.
Door jambs — Make sure they're dry so you don't get 'weeping' drips later.
Exhaust tips — Give them a quick wipe, it's the little things that make it look pro.

Watch Out

NEVER wash your car in direct sunlight when it's over 30 degrees. The soap and water will dry instantly, leaving spots that are a nightmare to get off. Also, steer clear of those 'brush' car washes at the servo, they're basically sandpaper on a stick.
