How To Choose The Best Lubricant For Sliding Glass Door?
Which Types Of Lubricant Are Safe For Sliding Glass Door?
Some materials used for sliding glass door tracks (aluminum or vinyl) and rollers (plastic or metal) can be damaged by petroleum-based products. So, make sure that your lubricant types for sliding glass doors are safe for them.
Silicone
Silicone-based lubricants are considered as the safest option for sliding glass doors because they are compatible with a wide range of materials such as aluminum, vinyl, plastic, and glass. It is not only low in toxicity but also leaves a dry and non-sticky surface after applying.
PTFE (Polytetrafluoroethylene)
It’s also safe to use PTFE-based lubricants on sliding door tracks and rollers because they are non-toxic. Thanks to great lubrication properties, this ingredient can create a slippery and low-friction surface for smooth movements of the door.
Graphite
This is also safe to use on sliding door tracks and rollers. Because of its dry and non-sticky nature, the graphite can minimize the risk of attracting dirt and dust.
Mineral Oil
Although mineral oil is also safe, it is not as long-lasting as silicone and PTFE lubricants.
Water-Based Lubricants
This type is safe to use indoors because it doesn’t emit harmful fumes and odors. However, it isn’t effective in preventing the buildup of dust and debris, especially; you have to reapply frequently.
How well the temperature resistance of your lubricant is?
Some lubricants can perform better in extreme heat or cold, so it’s very important to determine the temperature conditions in your area to choose a suitable one. Although most lubricants are designed for extreme temperatures, it’s better to read the product label and manufacturer’s recommendations to make sure that the lubricant performs effectively with your place’s temperature condition. Don’t forget to check the moisture level in your region as well since some are more water-resistant than others.
What Are The Best Forms Of Lubricants For Sliding Glass Door?
Each of them has their own benefit. You should choose one based on what you need.
Spray Lubricants
This is the most convenient form because the combination of aerosol cans and nozzle helps you apply the lubricant precisely. Moreover, the aerosol format allows you to reach tight spaces and crevices in the door tracks and rollers straightforwardly. Normally, silicone-based and dry-film lubricants are available in spray form.
Liquid Lubricants
Liquid lubricants are packed in squeeze bottles or dropper containers. These designs can stop you from applying too much and help you direct the lubricant to specific areas exactly. Silicone-based lubricants have a liquid form.
Gel Lubricants
Compared to liquid lubricants, gel lubricants have a thicker consistency that is less to drip and run, so this form works well for vertical surfaces and areas which require the lubricant to stay in place. You can easily find silicone-based lubricants in gel form.
Powder Lubricants
The powder lubricant is dry, so you will apply it by dusting and sprinkling. This form can prevent sticking and avoid attracting dirt and debris. It usually contains materials such as graphite and PTFE.
Stick Lubricants
This form looks like deodorant sticks and solid balms which are applied by rubbing it onto the track and rollers directly. I strongly recommend this type for spot lubrication because it is less messy than others.
Wax Lubricants
Some wax-based lubricants include paraffin wax and beeswax. How to apply it is similar to stick lubricants. This form can function as a lubrication, but it isn’t long-lasting.
Foam Lubricants
This is a foam spray format that clings to surfaces, so it is helpful for vertical sliding glass door tracks. Typically, silicone-based lubricants have this foam form.
Penetrating Oils
This form has a thin layer of oil that can seep into tight areas and dissolve corrosion and rust.
Which Brands Make The Best Lubricant For Sliding Glass Door?
WD-40
This brand that was founded in 1953 is famous for lubricants and maintenance products. They can not only loosen rusted and stuck parts, displace moisture but also protect against corrosion.

If your door rollers are misaligned, your doors can’t glide smoothly. What you have to do is to consult the manual to adjust the rollers properly as long as they are aligned with the track.

How to fix sliding door off track?

Inspect the rollers to know if it is damaged or worn. Replace if any.
Clear the tracks by removing any debris, dirt, and obstructions with a vacuum cleaner, a brush, or a screwdriver.
Aren’t the rollers damaged? But is the door still off track? The problem may be the height. The rollers with adjustment screws allow you to raise and lower the rollers until they align with the track.
Put the door back onto the bottom track and adjust as long as it fits the top track as well.
Test the movements of the door by sliding it back and forth. If it works improperly, you may need to adjust more.
Lubricating the tracks and rollers can maintain the door’s smooth movements.
Make sure that all screws and hardware are tightened properly.
The weatherstripping must be installed properly to maintain a great seal around the door.

How to remove sliding glass door for cleaning?
Prepare the area by clearing inside and outside the area around the sliding glass door.
Secure the sliding door in place for safety.
Laying down the floor inside and outside the door with plastic sheeting, padding, or blankets to keep it from damages and scratches.
Get rid of the door stopper with a screwdriver if any because this item can protect the sliding glass door from lifting off the track.
Remember to slide the door open partially to leave enough room for you to access both sides.
Lift the door along the bottom edge or by the frame straight until it completely clears the bottom track.
After lifting, put the wood blocks or dowels on the bottom track to stop the door from sliding back into the place accidentally.
Set the door on a secure and flat surface such as a sturdy table or a sawhorse without being tipped over easily.
Clean both sides of the glass door with a glass cleaner or a mixture of water and vinegar. Meanwhile, you can handle the frame and tracks with a vacuum cleaner, a brush, and a damp cloth.
How to adjust rollers on sliding glass door?
Remove the door to adjust the rollers easier if essential.
Look for adjustment screws on or near the rollers. Turning the screws with a screwdriver or an appropriate tool clockwise can raise the door while turning them counterclockwise can lower it.
In case your door isn’t level, adjust a roller higher or lower than another by turning the adjustment screws.
Can you use Vaseline for sliding door track?
You can use Vaseline as a short-term lubricant for sliding door track, but it isn’t an ideal long-term solution. Vaseline will attract dust and dirt over time, making the track sticking easily and damaging the rollers.
