How to lube a speedcube (and how to keep it turning smoothly)

A speedcube that feels scratchy, sticky or slow often does not need replacing. It needs a little lubricant and the right tension. This guide covers the basics for the most common type of 3×3.

What lube to use

Cubers use lubricants made for puzzles, usually silicone-based. They come in light and heavy versions and in different thicknesses, which changes how fast and how stiff the cube feels. A light lube makes a cube faster and more slippery, and a thick one makes it more controlled and slower.

Do not use household oils, cooking oil, WD-40 or grease on a cube. They can attract dust, make it sticky or damage some plastics.

What you need

• A small bottle or tube of puzzle lube with a fine tip.
• A clean cloth or paper towel.
• A small screwdriver, if your cube has screws.
• A clean tray or small box so the pieces do not roll away.

Step by step

1. Take the cube apart. On most standard speedcubes you turn the top layer about 45 degrees and pull out an edge piece, then the rest comes apart. Look up a short video for your exact model if you are not sure.
2. Wipe the pieces if they are dusty or sticky.
3. Add a little lube. A very small amount on the inside surfaces where the pieces touch the core is usually enough. More is not better: too much can make the cube feel slow or sludgy.
4. Put it back together and turn each face a few times to spread the lube.
5. Adjust the tension (see below) and test the cube.

Tension and springs

Many speedcubes have adjustable springs under the centre caps or screws. Tighter tension holds the layers together more firmly and makes the cube easier to control. Looser tension makes it faster and more likely to pop. If you are a beginner, a slightly tight cube is easier to control.

Magnets

Some speedcubes have tiny magnets built in. They help layers click into place and stop the cube overshooting. If your cube has adjustable magnets, you can change the strength on some models.

Keeping it in shape

• Do not leave a cube in a hot car or direct sun.
• Wipe it now and then.
• Store it in a bag or case.
• If it starts to pop, check the tension and screws before blaming your turning.

Common questions

How often should I lube a cube?

When it starts to feel scratchy, sticky or slow. For a cube used daily, that might be every few weeks or months. A cube that is rarely used may not need it at all.

Can I use too much lube?

Yes. Too much makes the cube feel slow and gummy and can collect dust. Start with very little and add more only if needed.

Does a new cube need lube?

Many speedcubes come lubricated, but they often feel better after a little adjustment. Try it before you add anything.

Is it safe for a child to lube a cube?

Yes, with some supervision, because the pieces are small and the lube should be kept away from the mouth and eyes. Wash your hands afterwards.
