How to remove excess wax from your car

It's the little things that help to keep cars shining for longer. One common issue that can trip detailers up is not removing old or excess wax before applying new wax to your car’s bodywork. It’s important to remove the old wax before applying new wax or a ceramic coating, over time wax buildup can dull the paintwork and stop you from achieving the best results.

Here are some of the best method for safely and effectively removing wax from the paint of your car.

Understand what type of wax you’re using on your car

Before you get started removing the old wax, it’s a good idea to understand what type of wax you used. Synthetic polymer waxes and natural carnauba waxes require different removal techniques. Before you buy any removal products, make sure they will work with the type of wax you’re using.

Wash your vehicle

Start by washing your car thoroughly. For best results, use a high-quality professional grade car cleaning product like CarPro Reset Intensive Car Shampoo. These products are designed to break down wax and other build up easily. Avoid using dish soap or household cleaners on your car as they can strip the protective coating on your car. Wash your car in the shade to prevent water spots from forming.

Use a clay bar to remove excess residue

Adding a clay bar to your car detailing exterior routine will help prevent that wax buildup you’re trying to avoid. After washing, use a clay bar to remove any residue or contaminants from the surface. Start by dragging the bar lightly across the car’s surface. You’ll need to apply a lubricant spray to help the clay bar glide smoothly. It’s important to only use a clay bar on a clean vehicle and to keep it clean during the process. If you drop the bar, use a new one — otherwise you’ll rub contaminates into your paint. Clay bars are affordable and worth their weight in gold, so it’s a good idea to always keep a couple on hand.

Best for:

Clay bars and clay glide spray are a great affordable option and achieve long-lasting protection. They’re also easy to use and be used repeatedly, as long as they are kept clean.

Use a pre-wax cleaner

Another option for prepping your car is a pre-wax cleaner. These cleaners are formulated to remove old wax while preparing the surface of your paint job for a new coat of wax. Apply a pre-wax cleaner, like CarPro’s Erase Intensive Oil and Polish Cleaner, with a micro fibre cloth and work it in a circular motion. These cleaners are safe to use on most paint finishes and will dissolve the wax without disturbing the underlying paint.

Best for:

Anyone looking for a multipurpose cleaner should consider a pre-wax cleaner. CarPro’s Erase Intensive Oil and Polish Cleaner can be used on windows, tires and removes polish residue and dust with ease. It’s a great all-round tool to have in your detailing arsenal.

Mechanical wax removal techniques

For stubborn wax removal, dual action polishers are adept at removing old wax. These should be used with a soft foam pad and with caution. Some mechanical removal tools can damage the paint if you’re not careful.

Best for:

Those experienced with operating a polisher. If you’re new to mechanical polishing, start with a low-speed setting and slowly increase the speed to a level you’re comfortable with.

Professional grade cleaners versus household cleaners

While dish soaps are known for their degreasing properties, they’re too harsh for use on your car. Regular use of household cleaners like dish soap or vinegar on your car will strip the protective oils from the paint, dry it out and cause damage over time.

If it’s an affordable wax removal solution you’re after a simple clay bar and degreaser is the best option.

How to check if the old wax has been removed

Here's how to know if you have removed the wax from the exterior of your car.

Water beading test

Wax causes water to bead along the surface of your car. After removing the old wax, lightly spray water on your car’s surface. If the water forms tight beads, there may still be wax that needs to be removed. If the water falls off in loose beads, you’ve.

Find the right lighting

After washing your car, give the exterior a thorough inspection in good lighting. Wax residue often leaves a hazy or cloudy appearance in the paint’s shine. It can also create an uneven look to the shine that can be hard to see if you’ve washed your car in the shade. If you see any of these signs you may need to run your clay bar or degreaser over these areas again.

Give it a touch test

Once you’ve removed all the wax from the surface of your vehicle, run your fingers along the paint job. If there's any wax left on the paint it will feel smooth or even slippery and still needs some work.
