Gather Your Cleaning Supplies
- Soft-bristled brush or toothbrush

Power Down and Remove Batteries
Before cleaning, ensure the drill is turned off and remove the battery (such as the DEWALT 20V MAX 5 Ah Lithium Ion Battery) to prevent accidental activation and electrical damage.
Clean Exterior and Ventilation Areas
- Use compressed air to blow out dust from vents and crevices, holding the can upright to avoid propellant spray.
- Wipe the exterior with a dry or slightly damp lint-free cloth.
- For stubborn grime, lightly dampen the cloth with isopropyl alcohol and wipe gently.
Inspect and Clean the Chuck and Bit Area
Use a brush or compressed air to remove debris from the chuck and around the bit holder. If dirt is stubborn, remove the bit and clean the chuck with a damp cloth. Do not submerge or soak the drill.
Disassemble if Necessary for Deep Cleaning
