Silicone spray is typically seen as a lubricant for noisy door hinges. But, you can also use silicone spray on car handles and hinges to protect against freezing or spray it in a rusted lock to loosen the internal mechanism, allowing you to turn the lock or at least recover a stuck key.

To find the best silicone spray for your purposes, consider whether you need a food-grade product or if you will use it outside of the kitchen on fabric, metal, wood, plastic, or rubber surfaces. Start your search with some of the recommendations listed below.

Before choosing a silicone spray, take a few minutes to educate yourself on the most important shopping considerations to keep in mind.

If you decide to use silicone spray around the home or in the garage, consider how you intend to use the spray. Depending on the purpose, you may want a compact product you can carry in your car, or you might benefit from something that comes with a straw so you can direct the spray to a narrow location with high precision.

Silicone sprays also come in either a wet or a dry form. The wet spray is ideal for vertical or upside-down surfaces because moisture in the formula helps the spray to adhere to the surface while it dries. Dry sprays are suitable for working on more sensitive equipment because the mist evaporates quickly and leaves behind a protective film.

To ensure that a product meets your needs, consider the silicone spray formula. You can typically find the chemical composition used in the product by reviewing the manufacturer’s website, where an MSDS (material safety data sheet) for the spray must be available.

Silicone sprays normally contain about 1.5 percent silicone, but this can increase to 3.5 percent while still remaining a spray. High silicone sprays are best for lubricating heavily-used joints and machinery. You should also review the formula and the manufacturer’s recommendations to determine whether you can use silicone spray on certain metal, wood, plastic, or other materials.

A food-grade silicone spray can be used on many kitchen tools and appliances, including the hinges on your fridge or the slide on a meat slicer. Although a food-grade spray will contain flammable components like 1,1-Difuorethane to help penetrate through rust and other contaminants, these harmful ingredients in the spray evaporate away after applying it, leaving a protective, lubricating film that won’t end up in your food.

While a food-grade spray is safe to use in and around the kitchen and other food preparation areas, it should not be confused with an edible product. What this means is that it is not safe to eat silicone spray, regardless if it is food-grade or not, because the product’s composition is harmful to humans.

The silicone lubricants you use will need to be able to remain effective at the temperatures it’s exposed to regularly. For example, suppose you use silicone spray on your grill to protect it from rust and moisture damage. In this case, it’s important to invest in a silicone spray with a very high maximum temperature to ensure that you won’t be burning the spray while you cook and having to reapply immediately afterward.

Depending on the product, the effective temperature range can vary significantly, with some silicone sprays having minimum temperatures of -100 degrees Fahrenheit while others have high-temperature maximums that exceed 1000 degrees Fahrenheit. If using the silicone spray on windows or doors, choose a product that will hold up to seasonal temperatures.

Silicone sprays dry at different rates depending on the spray’s viscosity, the material it is used on, and the amount of spray applied. However, most silicone sprays dry very quickly, typically taking only a few minutes to achieve a consistency that is dry to the touch. This is because many silicone sprays use flammable components for penetrating oil and grime to form a better seal, but these penetrating components rapidly evaporate, leaving only the protective lubricant and sealant.

If you are using the silicone spray for waterproofing or sealing, you will want to wait at least 24 hours to ensure that the spray is properly cured. Otherwise, you can use your appliances, doors, windows, tools, or other products almost immediately after application.

A silicone spray’s versatility refers to the materials it can be used with and whether its primary design is for lubricating, sealing, or a combination of both. If you are looking for a general-purpose silicone spray for around your home then you will want to find a product that can be used with wood, metal, plastic, vinyl, and rubber surfaces.

Consider finding a silicone spray that is non-staining so that you don’t have to worry about leaving a permanent reminder on your appliances or door frames. While most silicone sprays are both sealants and lubricants, there are products specifically designed to provide better waterproofing and others for easily penetrating through layers of rust for more efficient lubrication.

Selected with those shopping considerations in mind, the recommendations below are some of the best silicone spray options on the market for home and workshop repairs.

When you set out to apply silicone spray, keep these tips in mind:

Before investing in a new silicone spray, take a look at these frequently asked questions and their answers below.

Silicone spray is used to properly lubricate metal, wood, rubber, and plastic while providing a water-resistant barrier. However, once a surface has been sprayed, it becomes difficult to paint, so you will want to plan out your projects before applying it to every exposed hinge.

Silicone lubricant is not completely waterproof, but it is water-resistant and naturally repels water from any surface you spray.

No, silicone sprays won’t damage plastic. They actually work very well to lubricate and protect plastic surfaces.

Silicone spray can improve rubber and help keep the material soft and pliable.

It normally takes just a few minutes for spray lubricants to dry but can take up to 24 hours to fully cure.

You can remove silicone spray using a rag or cloth and denatured alcohol. If you don’t have denatured alcohol, you can use rubbing alcohol or another solvent. After wiping the area clean of silicone spray, you should rinse it with warm water before drying.
