Clean and lubricate the drawer runners: Often, a simple cleaning and lubrication can fix the problem. Use a soft cloth to wipe away any dirt or dust from the runners, then apply a thin layer of dry lubricant such as silicone spray, graphite powder, or paraffin wax. Be careful not to over-lubricate, as this can attract more dirt.
Tighten the screws: Check all the screws that hold the drawer runners and drawer in place. Make sure they are snug and not loose. Tighten any loose screws with a screwdriver.
Adjust the drawer runners: If the drawer runners are not aligned properly, it can cause the drawer to squeak. Check that the runners are level and that the drawer is sliding smoothly in and out. If necessary, adjust the runners by loosening or tightening the screws that hold them in place.
Replace the drawer runners: If the runners are damaged or worn out, they may need to be replaced. You can purchase new drawer runners from a home improvement store. Be sure to measure the length of the old runners before purchasing new ones.
Use drawer liners: Drawer liners can help to reduce friction and prevent the drawer from squeaking. Place a liner made of felt, rubber, or silicone in the bottom of the drawer.
