Wet Weed Eaters

Weed eaters are not designed to be waterproof or water-resistant, meaning, ideally, they should not get wet. Of course, a few drops of rain won’t break the machine, but let’s discuss what moisture does to a weed eater.

Can a Weed Eater Be Exposed to Water?

Weed eaters are not waterproof, although they won’t break immediately when it comes into contact with water. So if it starts to rain while you are weed-eating, you should get the weed eater to a dry environment as soon as possible.

If you’re working with a weed eater that uses a metal blade, it will start to rust and eventually might break. If you have string attachments, rust would not be a problem. However, corrosion might.

This is particularly the case for an electric weed eater.

These should be enough to prevent your whole machine from getting clogged.
