ᐅ How to Make BILLY Shelf Doors Operate Smoothly – Lubrication Tips

Hello everyone,

I own a BILLY bookcase with doors that have unfortunately become somewhat stiff after some use. Especially the hinges sometimes stick slightly, making opening and closing a bit difficult. I’m interested in which lubricants you would recommend to make the doors move smoothly without damaging the surface of the bookcase or the hinges.

What are the differences between common lubricants like WD-40, silicone spray, Teflon-based oils, or traditional machine oils in terms of their use on furniture fittings? And are there any precautions to prevent dirt from sticking to the lubricant or to avoid it becoming sticky?

I would appreciate it if you could share your experiences with suitable products or tips on the correct application. Thank you!

To improve the smooth operation of BILLY cabinet doors, I generally recommend using a dry lubricant such as a PTFE-based spray or silicone spray.

WD-40 or conventional oils may provide temporary lubrication but often leave residues that attract dust and cause sticking over time. This can reduce ease of movement.

It is important to apply the lubricant sparingly and then wipe off any excess with a lint-free cloth. The hinges should be as clean as possible before application (remove dust and large dirt particles beforehand).

Warning: When using silicone spray, make sure it does not get on painted or veneered surfaces, as it may cause changes in gloss.

Silicone spray works very well. Use only a small amount to avoid attracting dust.

Avoid WD-40, as it becomes sticky over time.

Retighten screws if necessary.

This is an important point. I would like to add that the hinges of BILLY cabinet doors are usually made of steel or zinc die-cast. Therefore, corrosion-resistant products should be used. A high-quality Teflon-PTFE spray is ideal because it leaves a dry lubricant film that does not stick.

For application, I recommend the following procedure:
1. First, remove the doors and clean the hinges with a dry cloth to remove loose dust.
2. Apply one or two short sprays of the PTFE spray directly onto the moving parts.
3. Rehang the doors and open and close them several times to distribute the lubricant well.
4. Wipe off any excess lubricant immediately after application to prevent unnecessary dirt buildup.

Additionally, if there is strong resistance or squeaking, the guide rails can be lightly treated with graphite powder, which is also dry and does not attract dust.

If you like, you can also check the screws, as stiffness can sometimes be caused by slightly loose fittings.

I’m curious: do you mainly use the BILLY unit for books or for heavier items? Sometimes the weight puts extra strain on the hinges and can contribute to slower movement.
