Tips And Tricks To Know When Your Car Wax Has Dried

Taking the wax off too soon is a major problem. I’ve made a research to help you understand: what is that perfect moment to slip the microfiber over and buff out your car?

Here comes a hold-true list of tips:

  • Follow recommendations of the wax manufacturer
  • Spotting dark streaks and stains during the application? Prepare to wait for the upper limit stated on the label
  • Smell. Natural waxes smell like candy. Weakened odor indicates that it’s time to buff out
  • Make the swipe test. Remember how you drew on a foggy glass? The same clear mark should remain when you run your finger over the dried wax. If your finger smears, it means that the coating is not ready
  • Gum-like consistency of the surface means it’s ready to be removed

What Affects Wax Drying Time

The main contributors are ambient air temperature and humidity. The presence of wind, time of day, and air composition are also influential. 

This is a table based on the results of other car lovers.

To understand when to remove the haze from the car, you can refer to the values in the table closest to your numbers (ask google about local weather)

Looking closely, one can conclude that the less humid the air, the faster the components dry out. Wind and heat will also speed up the process. However, do not overdo it by putting the car in direct sunlight, it will only complicate the stage of cleaning the car. Ideally, you should do it in a dry garage, at moderate temperatures. If the outside index is below 55F and the humidity tends to 100%, it is better to postpone the activity.

The shape and composition of the product affect the final timer before polishing. This is due to the chemical and physical properties of the substances. For example, natural carnauba pastes require up to 10 minutes on average. While synthetics need up to twice as much, from 10 to 20 minutes. Liquid solutions usually contain petroleum and solvents which make it easier for them to spread over the surface. Higher evaporation rate, meaning less drying out.

The thickness of the wax layer makes a difference. The thinner you spread the product on the surface, the faster it will be ready for removal. You can easily check this by running a clean and dry finger over the treated surface after some time. If your finger does not stick and there is some sort of dust on it, then you have done everything right. Otherwise, you may want to wait a little longer.

Сommon Mistakes Related to Drying of Wax

When I started researching the topic, I was most confused by two words: drying and curing.

I want you to understand the big difference to save tons of time. They are often used interchangeably, but the thing is they are not the same.

Drying: the time it takes for sealant or wax product to form a residual (haze) on the surface after application. It changes depending on the composition of the product and environment. Once you remove the haze, it’s curing.

Curing: a process of “healing” of the product. Time to set around and bond with the paint layer of the car. One reason for the confusion is that the drying time for carnauba coincides with curing, but for synthetics items timer can reach up to 72 hours. Imagine you are painting a wall. If you keep smearing liquid paint on the wall, the thickness of the coat is unlikely to change. You would just be transferring paint from the wall to the can and vice versa. Now imagine that you apply a coat and let it heal. Then the new paint will have no problem laying on top of the old paint. It’s the same with the car.

Difference between Dry and Cure processes

Rubbing Technique

The label refers to the optimum 15 minutes, you follow the advice and check the wax after a quarter of an hour. It’s not ready… what could it be and how do I know what to do?

The thing is that the dampened cloth or applicator pad has absorbent properties. You are spreading the wax over the surface and at the same time, you are absorbing it back in. This affects the overall drying time. The problem can be avoided by moistening the cloth in advance with a little liquid. It is best to use a little of the same product that you rub in.

Surrounding

The manufacturer’s instructions (including approximate drying time and tips) imply that you avoid the following mistakes:

  • Waxing the car in direct sunlight:
    The car is in direct sunlight. It may seem that the sun will speed up the process and you will save time. In practice, you’ll only spend more effort scrubbing off your metal friend. Especially if it’s painted in darker shades that absorb better and hold the sun’s heat longer. Black is the most affected color.  It is better to place the car in the shade or in a garage 
  • Waxing at cold outside temperatures:
    At values below 55 degrees F, it is better to postpone the process until it gets warmer outside the window. Bear in mind that it always gets cooler in the evening
  • Waxing at extreme humidity:
    At 100% humidity, water from the air will form dew, making it very difficult to determine the right time to remove the wax

Related Questions

How long to leave wax on the car?

The usual values for liquid waxes are 5-10 minutes, while the typical range for pastes is 10-20 minutes. If you compare natural and in-lab products, the latter takes a little longer to dry, up to 30 minutes for optimal conditions (60 to 80 degrees F and humidity up to 80%)

Can I leave wax for a long time?

Nothing serious will happen. The only downside is that it will be harder for you to remove the wax when you need to do so. Especially if you have used a machine. Contaminants and dust from the air will stick to the residual layer, making the buffing off process more time-consuming.

How to speed up the drying of the wax?

If you provide a temperature of 60 to 80 degrees F and the lowest possible humidity, the drying process will go the fastest. The thickness of the layer to be applied also has an effect. You want a thin, barely noticeable coat.

Are liquid waxes better than pastes?

Those are two forms of the same thing. Pastes are better for handwork, while liquids are more suitable for applicator pad. A popular opinion among enthusiasts is that paste is more reliable in terms of protection, although it also has certain disadvantages. Liquids, on the other hand, have quicker and more practical application. Which is a goldmine for modern automobilists.

Key Takeaways 

  • Streaks and dots are clear indicators of long drying time. Prepare for an upper limit stated on the label, or comparison table listed above
  • Swipe a finger across the waxed surface after 5 to 30 minutes, depending on the product
  • Pay attention to consistency. The ready-to-remove wax will be slightly stickier than the lotion
  • Be sure to read the back label of the product you are using to see the recommended time-frame
  • Don’t confuse drying with curing
