Plastic drawer runners don't always work as they should. Try these steps to lubricate your drawer's plastic runners in only a few minutes using soap, a candle and WD-40.
Clean out the drawer
Make the process easier on you by cleaning out the drawer before removing the drawer from its runners. Once you've taken out the drawer, clean the runners using a damp washcloth or paper towel to remove dust and debris. Allow the runners to completely dry before proceeding to the next step.
Apply the lubricant
A variety of soaps and candles will work for this process. Take a bar of soap and rub it along each of the runners. As you press the soap into the runners, be careful not to press too hard to avoid cracking the plastic parts. If you don't have soap handy, you can use a wax candle. Run your fingertips along the runners to make sure that they are covered with soap or wax.
Apply the WD-40
Spray WD-40 onto the parts of the drawer that meet the runners. Lubricate this part of the drawer to make sure that the drawer runs smoothly on its tracks. Wipe off any excess lubricant that runs down the drawer with a paper towel.
Replace the drawer
Slide the drawer back into place slowly, ensuring that the drawer makes contact with the runners. Spray more WD-40 if the drawer or the runners squeak.
