Therefore, it's important to clean the tracks thoroughly to maintain the hygiene and functionality of the door.

What You’ll Need

For this part, you’ll need the following materials:

  • A small vacuum
  • A screwdriver
  • Acetone
  • Lubricating grease
  • A toothbrush
  • Steel wool
  • A tack cloth
  • A terry cloth towel

An easy way to clean sliding door tracks is to wipe them with a slightly oily cloth. This will help to keep it operating smoothly. If you notice some resistance to movement, you may need to remove the door to clean it thoroughly. If this is the case, simply follow the instructions below:

  1. First, remove the sliding glass door. There are two ways to go about this: you either grasp the door at each end and lift it upwards as you pull it towards your body, or use the screwdriver to raise the lower rollers off the tracks and then pull the door towards you as you lift it.
  2. Next, use the miniature vacuum to remove sand, gravel, bits of leaves and bark, or any other debris that has gotten into the door’s tracks. Remember to vacuum both the top and bottom of the door.
  3. Clean up any traces of rust. If your sliding doors are made from a material like aluminum, you should check if there are any signs of rust. This could cause your door to stick. Gently use steel wool to remove the rust, and then wipe the surface with a tack cloth to get rid of any metal particles.
  4. Changes in temperature, exposure to the elements, and regular use of your sliding glass doors can cause grime to appear on the tracks. This will eventually thicken and lead to a malfunctioning sliding glass door. Use a brush to clean sliding door tracks and remove the grease and grime, or dip a toothbrush in acetone and use the wet bristles to clean the tracks’ top and bottom. When you’re done, wipe the tracks with a terry cloth towel.
  5. Lastly, make sure to grease the tracks once they have been thoroughly cleaned. Apply a small amount of lubrication on the door rails, and then put the door back in its position. Glide the door several times to spread the lubricant along the wheels and tracks.

Step 2: Clean the Glass Surface

Over time, the door’s glass will accumulate dirt, dust, fingerprints, and other grime that affects the appearance of the door, making it difficult to see through. Regularly cleaning the glass surface can help to remove these stains and keep the glass looking crisp and clear.

What You’ll Need

To start cleaning glass doors, gather the following:


It’s important to keep in mind that you shouldn’t use any type of scraping tool to remove stuck debris. Instead, repeat the steps below as many times as you need so you can get squeaky clean sliding doors without damaging them.

  1. Pick a side of the door and dip a clean rag in soapy water and use it to wet the entire glass surface. This will help to loosen dirt deposits.
  2. After several minutes, wipe off the soapy water using a clean cloth or some paper towels. Work your windows from top to bottom.
  3. Apply a mild window washing solution using a microfibre cloth, foam sponge, or any other non-abrasive cleaner.
  4. Once you’ve covered the surface with the cleaning solution, wipe it off immediately using the squeegee, as waiting too long can cause streaks or blotchy spots when removed.
  5. Repeat the steps above on the other side of your sliding door.

Step 3: Clean the Door Frame and Hardware

The door frame and handles are used extensively, which makes them most likely to accumulate bacteria, smudges and smears over time. You definitely don’t want to skip this part!
