How to Wash Inside Double-Pane Patio Doors
Figuring out how to clean inside double-pane patio doors can be daunting. Nobody likes the idea of taking apart their door, but the process is easy once the seal is broken.
Use our brilliant ideas for cleaning in side double-pane patio doors with everyday items like rubbing alcohol, dish soap, vinegar, toothpaste, or a dehumidifier. Deep cleaning sliding glass door tracks with items from your home is the best way to make your sliding doors look fantastic without buying costly cleaning supplies.
Cleaning In Side Double-Pane Patio Doors
Put down a sheet of plastic with two saw horses on top. Lift the sliding glass door up and out of the track by dragging the base forward and out. Place the door on the saw horses horizontally. Unscrew the frame and lift the outer metal housing around the glass panels away from the panes of glass.
Examine the spacer through the glass. The gas was injected between the glass in many older devices by creating a hole in the spacer. If you locate this hole, you can drill back through it. Fit a 1/4-inch drill bit and make a hole through the spacer’s center, wearing gloves and safety goggles.
Drill an additional hole near one corner of the bottom spacer. The first hole is to fill the void with cleaner, and the second hole acts as a drain. Now you’re ready to clean inside the glass windows.
How to Clean Inside Double-Pane Patio Doors
Rubbing alcohol is a smart way to remove dirt without splurging on new windows. The solvent properties of rubbing alcohol cut through the gunk and grime inside your glass patio door and then evaporate. Use the drilled holes you prepared to introduce the alcohol to the space between each window pane.
Stick the rubber tubing into the upper hole in the spacer and insert the funnel into it. Pour the alcohol through the funnel and inside your sliding patio door panes. Fill the glass void with alcohol by squirting it via the upper tube.
Tilt the door side to side and flip it over to ensure the alcohol reaches all regions inside the glass. Tip the door upright, allowing the alcohol to flow out of the drain hole, bringing any debris with it. Let the remainder of the liquid alcohol dry for a few days until the window is clear.
Washing Inside Double-Pane Patio Doors With Mild Soap
Mild dish soap is perfect for cleaning everything from inside the glass panes to the vinyl window frame and even the sliding door track. Mix a tablespoon of liquid dish soap for every cup of warm water to make the best homemade shower glass cleaner to cut through gunk and grime.
Use a funnel and rubber tubing to pour the solution into the glass panel or apply it to exterior parts with a soft cloth. Don’t use a paper towel as they tend to leave paper pieces on the glass. Rinse out inside the glass by adding distilled water to the highest drill hole, or use a damp cloth to wipe the outside and let the door air dry.
A Dehumidifier Removes Moisture From Sliding Glass Doors
A dehumidifier is an alternative option if you have condensation inside your French door but don’t want to put holes in the frame. When moisture from inside or outside your home enters the break in the seal around the glass, you’re left with a foggy window.
Set up a dehumidifier following the manufacturer’s directions and position it as close to your sliding glass door as possible. As the device draws moisture out of the air, it encourages the condensation between the glass panel to evaporate, giving you a better view.
Choose a dehumidifier appropriate for the size of the room for your patio door. An inadequate dehumidifier for the space will likely underperform, reducing the chances the fog lifts.
Remove Fingerprints From Glass Patio Doors
Use a homemade white vinegar spray to remove the fingerprints and smears from the outside of your patio glass panes and freshen the door frame. The mild acetic acid in distilled vinegar cuts through the gunk and leaves a sparkling finish. This vinegar solution can also be used for keeping your patio furniture clean and glass tables free from fingerprints.
Shake the sprayer and spritz the vinegar liquid onto the glass. Allow it to sit on the window for about 15 minutes before wiping it off with a damp rag. Continue the process until no traces of stains remain.
Clean Streaks off Glass Patio Doors With Toothpaste
Though you can’t use toothpaste between the glass panes, it’s an excellent cleaner to ensure the outside of the window is flawless. Although it may seem counterintuitive, toothpaste is a fantastic choice for cleaning glass patio doors in addition to your teeth.
Begin by spot-cleaning the sections with the most challenging stains. Use a soft-bristled toothbrush and a small amount of toothpaste to remove marks. Apply a small amount of traditional cream toothpaste to the stain and scrub in a circular pattern until the discoloration lifts from the glass.
Use a paper towel to wipe up the toothpaste. Wet a towel with distilled water and buff it to freshen the window and remove any debris or residue.
Precautions for Clean Sliding Glass Door Panes
A typical error in cleaning tempered patio glass is to leave strong detergents on it for a prolonged time. During the waiting period, the soap solution dries, leaving smears or flakes on the glass. To prevent undesired deposits from forming, properly follow the guidelines and rinse cleansers immediately.
Another typical mistake while washing glass is using the wrong type of cloth. Regular cloths disperse their fibers, leaving small fabric fragments all over the glass. Use microfiber towels to guarantee a smooth finish.
Avoid scuffing the surface of your patio door glass. Use gentle scrubbing motions at all times. Glass is prone to scratching, so start with minimal pressure and increase as required.
