How Often Should You Wax Your Car?

Washing your vehicle is one of the most common DIY car maintenance activities. Often conducted from a cosmetic standpoint, regularly washing your car also preserves the paint and prevents rust. Many people finish the car wash by waxing their vehicle – but how often should you apply wax? That’s the question we explore in this article. 

Why Do We Use Car Wax?

Regularly waxing a car is essential because it preserves the clear coat over a vehicle's paint. The clear coat is the layer that protects the paint from corrosive elements, including snow, rain, street salt, ultraviolet rays, and tree sap, among other contaminants.

When the clear coat wears away, the paint becomes susceptible to fading, discoloration, and rust. Applying wax is necessary to keep the exterior of the car in the best possible condition and to retain its resale value.

Waxing Interval

There is no exact answer for how often a car should be waxed. For some, twice a year is enough. For others, waxing is necessary every three to four months or with the change of seasons. Some people wax their vehicle as often as every eight weeks. 

The time interval depends on the environment the car is exposed to. For vehicles kept in climate-controlled garages, waxing is required less frequently. However, vehicles parked on the street and exposed to harsh winter weather or year-round direct sunlight require more frequent wax applications. 

The key is to wax a car at an interval that keeps the clear coat safeguarded. Determining that interval is based on the understanding that the wax will wear away on its own. The most obvious way to tell if the layer of wax is thinning is to observe how water beads on the vehicle's surface. Due to surface tension, wax causes water to bead up and roll away. When beading does not occur, no wax layer is present, meaning the clear coat is unprotected.

Another way to see if wax remains on the paint is to run a finger over the vehicle's surface. A waxed surface feels noticeably different than an unwaxed surface. The former has a smoother touch and allows a finger to glide effortlessly across it. An unwaxed surface feels rawer and resists sliding. If no wax is detected, it is time to reapply, regardless of how long it has been since the last application.

Types of Wax

The type of wax you use is also a determining factor of waxing frequency. There are several wax products, each with different formulations and results:

• Paste Wax – The most traditional wax formulation puts a thick, protective layer over a vehicle's clear coat. Due to its dense consistency, paste wax takes longer to apply, but lasts longer. Reapplication time is three to six months.
• Liquid Wax – Composed of a blend of natural wax and synthetic polymers, this wax offers a good defense against UV rays and gives a good shine. However, the coating is thin and may not last very long – as little as eight weeks.
• Liquid Polymer – This product is made from man-made chemicals but has the same properties as wax. It is often considered a synthetic wax. Although it is easier to apply and offers a similar protection level as wax, a polymer does not produce the same paint shine. Plan to reapply it every three to four months. 
• Carnauba Wax – This natural substance gives the paint a great shine but does not last very long and requires reapplication more often than other waxes on this list – anywhere from four to eight weeks.

Waxing Steps

Remember to wash your vehicle before waxing it to remove surface dirt, debris, and grease so that you can apply the wax cleanly and evenly over the clear coat. Not washing a car first can cause the wax to grind dirt and other particles into the paintwork.

To prepare your car for wax application, wash the vehicle and use bug and tar remover as needed. Depending on the vehicle’s condition, you may also consider using a clay bar to remove contaminants and create a smoother surface for wax application. Once the car is washed and the vehicle is parked in a covered area protected from the sun, you can apply the wax. From here, the application steps vary depending on the selected wax type. 

Apply wax to one section of the vehicle at a time. If applying by hand, once the wax has dried, use a buffing or damp microfiber cloth in circular motions to remove the wax. Alternatively, you can use a polishing machine to complete the job. Although much more efficient, the tool is pricey and can be complicated to use – carefully read the instruction manual before use. 

How Much Does Wax Cost? 

Most waxes can be purchased for $15 to $30, depending on the size. 

Given the potential tediousness of wax application, you may opt to have your car detailed and waxed by a professional. This costs $50 to $100 but saves you time and material costs.

Other Paint Protection Options

Although waxing is an important practice for preserving paint, it’s not the only option. One alternative is using a paint sealant that leverages synthetic elements to provide superior protection to wax – guarding the paint from high temperatures, mud, chemical detergents, and more. While paint sealants last months, ceramic coating lasts years. Composed of a silica-based liquid polymer, ceramic coating cures to form a hard shell, protecting the paint from road contaminants, bird droppings, and water stains. Unlike waxing, this is best applied by a professional and costs much more. 

The Verdict 

Ultimately, how often an owner should wax a car depends on multiple factors, including if the vehicle is garage-kept, the climate in which you drive the car, the amount you drive the car, and the type of wax you use. Consider these factors to determine the right interval between applications of wax.
