Can You Wax a Car Too Much?

Waxing your car, or applying any other type of paint protection like a sealant, is an essential step of caring for your car and ensuring the paint remains shiny and vibrant for years to come. But can you wax a car too much? Is there actually such a thing as over-waxing your car?

In this article, I’ll be talking about how often you should be waxing your car to keep the paint protected and looking nice and glossy. So let’s get started.

The Quick Answer

Waxing a car frequently will not cause issues but is often unnecessary. There’s no such thing as causing damage by waxing too much. However, only one layer of wax will bond to the paint at a time. Adding more layers won’t add extra protection or gloss. Waxing once every 2-3 months is optimal.

Pros of Waxing

There are many advantages to waxing your car, or applying any other type of paint protection like sealants or ceramic coatings. Here are some of the main ones.

It prevents dirt and other contaminants like iron fallout, bird mess, bugs and road tar from bonding to your paint.
Wax makes your car easier to clean because dirt doesn’t stick as well to a car coating in car compared to bare paint.
Waxing makes your car look glossy and wet. Cars always look best when they’ve been freshly detailed and waxed.
It repels water so you don’t get ugly water spots which can etch your paint and cause clear coat damage.
Waxes can help to protect your car from UV damage so the colour coat doesn’t fade.

Disadvantages of Waxing Often

So we know that waxing offers some great benefits, and it’s essential if you want your car to look good for as long as possible. But are there any disadvantages of waxing your car often?

There aren’t really any disadvantages to waxing your car, except it takes a while to do. Also, if you’re not doing it properly, then you can run the risk of damaging the paint.

As long as you’re following these steps, you won’t damage your paint.

Always use a clean and soft microfiber or foam applicator to apply the wax.
Make sure the paint has just been freshly washed, otherwise you’ll grind dirt and dust into the paint when you’re waxing.
Be gentle. Never scrub at the paint when applying or removing the wax.
Always use a plush, freshly washed and dried microfiber towel to remove wax. Never use rags or other types of towel.

There aren’t really any issues with waxing your car frequently, as long as you have the patience and are careful not to damage the clear coat through poor technique.

How Often Should You Wax a Car?

The frequency at which you should wax your car depends on a few different factors.

Firstly, it depends on how exposed your car is to the elements. If you store your car outside all the time, and drive it every day, then it’s far more exposed to dust, dirt and grime. Therefore, it should be waxed more often.

Secondly, it depends on what wax you’re using. Most waxes last between 2-3 months before they lose their water repellency and protective abilities. Other waxes last longer than this, some even last up to a year (usually synthetic ones, not traditionally carnauba waxes). However, some show waxes last just a week before they start breaking down.

Often the manufacturer will make a claim as to how long the wax lasts, however in practise it’s often less than this. I usually reapply the wax after around 2/3 of the time that the manufacture claims, just to be on the safe side.

Finally, it depends on how often you wash your car. The car shampoos and snow foams you’re using slowly break down the wax layer and remove some of the protection each time you wash your car. Even those that are pH neutral.

The simple act of washing your car will degrade the wax to some extent. So if you wash your car every few days, then you’ll need to wax it more often than if you wash your car every few weeks.

Generally, for most car owners waxing once every 2-3 months is optimal. If you really want to make sure that your car is well protected, and you wash your car often and store it outside, then you may want to wax it monthly. There is unlikely to be much benefit to waxing your car more often than once a month, unless you’re using a very short-lasting show wax.

Can you Wax a Car Too Much?

There isn’t an issue with waxing your car too very often, except it’s kind of pointless.

If there is already a good layer of wax on your paint, then adding more wax won’t do anything extra. In fact, when you go to buff that layer off, you will most likely remove all the wax you just applied.

Some car owners think that if they have a wax that claims to have a 1 month life span, and then they add two layers, that they’ll get two months life. And if they add three layers then they’ll get three months life out of it.

Unfortunately, it doesn’t really work like that.

Only one layer of wax will bind to your paint. So adding more on top makes no difference to the durability.

Personally, I apply one layer of wax, buff it off and then apply a second layer. But I only do this to make sure I’ve not missed any gaps with the first layer.

You only really need to apply one layer at a time. Then, when you see the water repellency properties diminishing, top it up with another layer.

More FAQs

Here are some answers to the most commonly asked questions about car waxing if you want some more advice.

Should I wax my car every time I wash it?

You do not need to wax your car every time you wash it. Most waxes last at least 2-3 months. You can tell when you need to wax the car again because when you rinse it, the water won’t bead up properly. If the wax starts to lose some of its water repellency, then apply another coat.

Does rain wash away car wax?

Exposure to frequent and heavy rainfall can degrade the wax faster. Storing your car outside can mean that you need to wax your car more often. If you notice that the water isn’t beading off the paint, then apply another layer of wax after you next wash it.

Can you leave car wax on for too long?

It it possible to leave car wax on your paint for too long. Always follow the manufacturer’s instructions when applying wax. Some waxes should be left on for 10-15 minutes, others should be buffed off immediately after application.
