How to Wash a Car
Without Wrecking the Paint.

Most swirl marks and paint defects aren't caused by driving, they're caused by washing. Here's exactly how to wash your car properly, what products to use, and the mistakes that are silently damaging your paint every time you clean it.

Why It Matters

How Washing Damages Paint

Every time you wash your car incorrectly, you're introducing fine scratches into the clear coat. Over time these accumulate into the swirl marks and haze you can see in sunlight. The culprits are almost always the same, the wrong products, the wrong technique, or the wrong mindset about what car washing actually involves.

Automatic car washes are the worst offenders. The rotating brushes in a tunnel wash drag grit across your paint at speed, introducing hundreds of fine scratches in a single pass. Even "touchless" washes use high-pressure chemicals that can degrade your clear coat over time. If you care about your paint, avoid them entirely.

The number one cause of swirl marks on well-maintained vehicles isn't driving or parking, it's washing. Getting the technique right is the single most impactful thing you can do to preserve your paint between details.

What You Need

The Right Gear Makes All the Difference

Two Buckets

One for your shampoo solution, one for clean rinse water. This is the most important piece of the process, it keeps contamination out of your wash solution.

pH Neutral Shampoo

Use a dedicated car shampoo that's pH neutral. Dish soap, household cleaners and generic detergents strip wax and coatings and can dry out rubber seals.

Microfibre Wash Mitt

A quality microfibre wash mitt traps dirt in its fibres rather than dragging it across the paint. Never use a sponge — they hold grit against the surface.

Microfibre Drying Towels

Large, plush microfibre drying towels only. Never use a chamois, bath towel or squeegee, all of these introduce scratches.

Wheel Brush and Dedicated Bucket

Wheels are the dirtiest part of the car. Use a separate bucket and brush for wheels, never use the same mitt on wheels and paint.

Grit Guards

Plastic grit guards sit in the bottom of your buckets and trap dirt below the waterline, stopping it from being picked up again by your mitt.

Step by Step

The Correct Way to Wash Your Car

01

Wash the wheels first

Always start with the wheels using your dedicated wheel bucket and brush. Brake dust and road grime from the wheels will splash onto the bodywork, so do them first, then rinse, before you touch the paint.
02

Pre-rinse the whole car

Rinse the entire car thoroughly with a hose or pressure washer before any contact. This removes loose dirt and dramatically reduces the risk of dragging grit across the paint during the wash.
03

Apply snow foam (optional but recommended)

A snow foam pre-wash applied with a foam lance loosens and lifts bonded dirt before the contact wash begins. It's not essential but significantly reduces the contamination you're washing through in the next step.
04

Two bucket wash — top to bottom

Load your mitt from the shampoo bucket and wash one panel at a time in straight lines, not circles. After each panel, rinse your mitt in the clean water bucket before reloading with suds. Always work top to bottom, the lower panels are dirtiest.
05

Rinse thoroughly

Rinse the entire car from top to bottom, making sure all shampoo residue is removed. Pay attention to door jambs, mirrors and panel gaps where shampoo collects.
06

Dry immediately with microfibre towels

Don't let the car air dry, water spots will form, especially in Queensland's heat. Use a clean plush microfibre drying towel and blot or drag gently across the surface. Never press hard or scrub.
07

Detail spray (optional)

A quick detailer spray after drying adds a light layer of protection and enhances gloss between full washes. Use a clean microfibre cloth and work panel by panel.
