Maybe you left your power tools uncovered in the back of your truck and it starts to rain. Maybe your basement flooded and now your tools are completely soaked. You get a sinking feeling, wondering if you have to go out and buy replacement tools. Or do you? Are power tools waterproof?
Most power tools are not waterproof, and should not be used in the rain or stored in places that are vulnerable to water. There are some companies (ex: Nemo Power Tools) that offer tools that are advertised as waterproof, but they are an exception. Most of the power tools you’ll find in a typical workshop will likely be damaged by water.
What to Do When Your Power Tools Get Wet
Sometimes situations are unavoidable and your tools inevitably end up wet. Even though they are not waterproof, you may still be able to salvage them. Here’s how:
Step 1: Make sure to unplug the tool (if it’s corded), or remove the battery (if it’s cordless).
Step 2: If possible, disassemble the tool as much as you feel comfortable with. This is so that you can have an easier time of drying the tool.
Step 3: Use an air compressor to blow out any water in the motor vents, as well as any other nooks and crannies of the tool. Start first with low pressure compressed air as to not blow water deeper into any nooks.
Note: Some people recommend using a heat gun, but I do not advise doing this as plastic parts of the tool could melt and completely destroy your tool.
Step 4: Place the tool in front of a fan on high for about a day or two.
Step 5: Reassemble your tool and test it out. It should hopefully be working normally again.
Keep in mind results may differ depending on the type of tool that got wet, how long it was wet for, and many other factors. Use your own discretion when attempting this at home.
