To clean a trimmer, switch it off, disconnect its power source, and brush away grass and dirt from the head, guard, and shaft. Follow the manual for wet cleaning or maintenance, then let each part dry before storing the tool.

A few minutes of cleanup can keep dried clippings from collecting around moving parts. For safe storage after cleaning, see our guide to storing a weed eater in the garage.

How do you clean a trimmer safely?

Disconnect power before cleaning or inspecting a trimmer. Remove the battery on a cordless model, unplug a corded model, or turn off a gas trimmer and let hot parts cool.

Wear work gloves and safety glasses while clearing debris. Keep hands away from the cutting line, and don't run the trimmer while cleaning it.

Check the manual for instructions specific to your model. It will tell you which parts can be removed and whether water or a particular cleaner is allowed.

How do you clean a string trimmer head and guard?

Brush loose grass and dirt off the cutting head and guard with a dry brush or cloth. Use a soft tool to loosen packed debris, taking care not to push dirt into openings or damage plastic parts.

If the spool needs to come out for a closer cleanup, follow the manual's removal and reassembly steps. Don't force the cap or spool if it resists.

Grass can wrap around the head or shaft, especially after trimming damp or tall growth. Clear tangles carefully and stop if debris is caught where you can't reach it safely.

A trimmer with a command-feed spool can still collect debris around its head. The WORX WG163 converts between trimmer and edger modes, and its head tilts 90 degrees.

Check that the spool is seated correctly before use, and follow WORX's instructions for feeding line. If string keeps snapping or tangling, see why trimmer string keeps breaking.

Can you use water to clean a weed eater?

Use water only if the manual permits it, and keep water away from electrical parts. For routine cleanup, a dry brush or cloth can remove loose clippings without wetting the tool.

Never submerge a trimmer or use a pressure washer. On a cordless model, keep moisture away from the battery contacts, controls, and motor area.

If the manual allows a damp cloth, wring it out first and wipe only the approved surfaces. Dry everything fully before reconnecting power or installing the battery.

What should you check after cleaning?

Inspect the line, guard, and visible parts for wear or damage before putting the trimmer away. Replace cracked or loose parts according to the manual, and don't use a tool with a damaged guard.

Check whether the line is tangled, too short, or worn. The right replacement depends on the trimmer's requirements, so compare them with what size trimmer line to use before buying.

The Greenworks 40V trimmer uses 0.065-inch dual line and has an automatic feed system. That makes it an option for routine lawn trimming if you want a cordless tool with variable speed.

Don't assume line from another trimmer will fit. Match the diameter and type to your tool's manual.

How should you clean a trimmer before storage?

Let the trimmer dry completely, then store it with its power source disconnected. Keep the tool in a dry place and position it so the cutting head and guard won't be crushed or snagged.

For battery models, follow the battery maker's storage instructions. Keep batteries away from moisture and extreme heat, and avoid leaving them attached if the manual says to remove them.

If you need replacement line, the DeWalt DWO1DT802 is 0.080-inch line in a 225-foot length. Check your trimmer manual first to confirm that diameter is approved for your model.

How to clean a trimmer before you put it away

To clean a trimmer before storage, disconnect power, brush off debris, inspect the line and guard, and let the tool dry fully. Use water only if the manual allows it, and follow its directions for removing parts or storing the battery.

Choose replacement line only after checking your model's requirements. Then store the trimmer in a dry spot where the head and guard won't be damaged.

Frequently asked questions

How do you clean a string trimmer head?

Disconnect the trimmer from its power source, then brush or wipe grass and dirt from the head. Remove the spool only as the manual directs, clear packed debris without damaging the housing, and let cleaned parts dry fully before putting the spool back.

Can you wash a weed eater with water?

Use water only if the trimmer manual allows it, and keep it away from the motor, battery contacts, switches, and other electrical parts. A dry brush or cloth is often enough for routine cleanup; never submerge the tool or spray it with a pressure washer.

Should you clean a trimmer after every use?

A quick cleanup after use helps keep wet grass and dirt from building up around the guard and cutting head. Disconnect the power first, remove loose debris, and check for damage or tangled line before storing the trimmer.

Should you remove the battery before cleaning a cordless trimmer?

Yes. Turn the trimmer off and remove its battery before cleaning or inspecting it, following the manual's steps.

This helps prevent an accidental start while your hands are near the cutting head; store the battery as its maker directs.
