Truck Curtains “Sticky” in the Track? Help Them Slide Again

Professional drivers may experience “sticky” truck curtains in the trucks they drive.

We have encountered this situation in both newer and older trucks.

This page shows how we remedied it in a Freightliner Columbia and Freightliner Cascadia.

First of all, the curtain connector installed in the track looks like this.

What we mean is that the connectors just seem reluctant to move down the track at all or in certain spots.

  • a hemostat (or pair of needle-nosed pliers),
  • a cotton ball and
  • WD-40 (shown below from, with which we have an affiliate relationship).

We prefer using the can of WD-40 with the “smart straw” as shown here.

He did this to help lubricate the area where the truck curtains will run.

This relieves the tendency for the curtains to be sticky.

Any further problems that might develop can be remedied by applying more WD-40.

If you make a direct application, make sure that you have a paper towel handy to catch any drips that may occur.

For the most effective aiming, you might consider using the attached straw.

WD-40 is an excellent lubricant but needs to be used in appropriate settings.
