How to Clean and Maintain Sill Track and Rollers on Andersen® Gliding Patio Doors

You may need to clean your gliding patio door's sill track, the bottom channel where the door glides, or lubricate your rollers, when there is visible debris, the operation is bumpy, or the operation requires more effort than normal.

When to Use This Article

We recommend following the instructions in this article to clean your gliding patio door's sill track and rollers and least once a year. If you live in a coastal, industrial, or agricultural area with higher levels of airborne materials like dirt, dust, smoke, and salt spray, we recommend following these instructions at least every three (3) months.

This Article Will Help You:

• Clean your gliding patio door's sill track.
• Lubricate your gliding patio door's rollers.

Safety Warning

Tools and Supplies Needed

• Soft-bristle brush
• Mild soapy water
• Clean water
• Andersen dry lubricant spray 

Let's Get Started

1. Clean Gliding Patio Door Sill Track

1. Open the patio door.
2. Use a soft-bristle brush and warm, mild soapy water to remove any dirt deposits or debris from the sill track.
3. Rinse off any soap residue with clean water.
4. Allow the track to dry before closing the patio door.

2. Lubricate Gliding Patio Door Rollers

Apply a dry lubricant spray to the rollers either by spraying it through the patio door's adjustment hole or by removing the panel and applying it directly to the rollers from the bottom of the panel. It is not required that you remove the panel.

• For information on where the adjustment hole is located and instructions on removing/reinstalling the panel, see Adjust Operating Panel on Andersen® Gliding Patio Doors.
• Important: Do not use lubricant on the track; this will cause the rollers to slide, instead of roll.

If your door's operation hasn't improved after completing the recommended cleaning and maintenance listed above, Contact Andersen® Windows and Doors for further assistance.
