What to Look for in a Brush for Lubing Mechanical Switches?

If you’re looking for a good quality brush which will evenly distribute the lube across each of the keyboard switch components to ensure a nice and crisp sounding keypress, here are some of the things that you need to look for in a brush for lubing mechanical switches.

Thin Tip

One thing you need to make sure when you’re getting a proper paintbrush for lubing mechanical switches is that the tip of the brush is very thin like 1 or 2mm. This is because the tip will be able to apply the lube fairly easily with a thin tip in comparison to a thicker tip that might not even fit into the switch housings.

Soft hairs

Another important factor is the quality of the brush hairs. If you’re choosing an acrylic brush, it’s best if you go for a brush with very soft and smooth hairs, this way you’ll be able to maneuver the tip of the brush inside the switches to make sure that you get lube applied evenly all over the brushes.

Slim handle

Getting a brush with a slim handle is also very important actually. A brush with a slim handle will be able to go deeper into the switches and won’t be difficult to use if you’re trying to lube smaller tactical or linear switches and would help in lubing the mechanical switches with ease.

What Not to Use to Lube Mechanical Keyboard Switches

People often think that whatever they have would work for lubing the keyboard switches instead of using actual brushes. This is bad because an uneven layer of lube or any hard press or push can actually damage the switch and create bigger problems. That’s why you should not use the following applicators to lube your mechanical keyboard switches.


People sometimes actually use a syringe to extract the lube from the tube and then directly put it onto the switches for “efficient” lubing. This is incredibly wrong because there’s going to be an uneven layer of lubing all over and the syringe might also damage the switch components ruining the perfectly good switches.

Bare Fingers

There are chances that you might think using your fingers to gently apply lube would be a good idea but as your finger would be bigger than the switch and won’t be able to get into the nooks and crannies, you won’t be able to actually perfectly lube your MX switches.


In order to get into every little space of the switches, a toothpick might seem like a good option. Well, it’s not. One because it won’t evenly distribute the lube onto the switches and two, it might actually damage your switches. So, steer clear from the use of toothpicks to lube your switches.

These are some of the more commonly used things that people end up mistaking for an appropriate substitute for actual paintbrushes and lube brushes. Ultimately, you shouldn’t be using anything other than a proper brush for lubing mechanical keyboard switches since they’re pretty inexpensive anyway.

Why Should You Lube Your Mechanical Keyboard Switches?
