- Soft-bristled brush or toothbrush
- Lint-free cloths or microfiber towels
- Isopropyl alcohol (70% or higher) for stubborn grime
- Compressed air canister
- Small screwdriver (if needed for disassembly)
Having these supplies ready will streamline the cleaning process and ensure safe, effective maintenance of your DEWALT tools.
Power Down and Remove Batteries
Before cleaning, always turn off your tools and detach the batteries. This prevents accidental activation and protects electronic components. Remove batteries carefully by pressing the release buttons, and set them aside in a dry, cool place.
Clean the Exterior and Ventilation Areas
- Use compressed air to blow out dust from vents, switches, and crevices. Hold the can upright and spray in short bursts to avoid moisture buildup.
- Wipe the outer surface with a slightly damp microfiber cloth—avoid excess moisture that could seep into electronic parts.
- If dirt persists, dampen a cloth with isopropyl alcohol and gently wipe surfaces for a deeper clean.
Ensure all areas are dry before reassembling or storing.
Clean and Inspect the Batteries
Use a dry cloth or a lightly dampened one with isopropyl alcohol to clean the battery contacts. Check for corrosion, swelling, or damage. If corrosion is present, gently clean with a small brush and alcohol. Do not submerge batteries in water or alcohol.
Ensure contacts are dry and free of debris before reinserting into the tool or charger.
Disassemble and Clean the Drill and Impact Driver (if needed)
If your tools have accumulated stubborn grime around the chuck or grip, use a screwdriver to carefully disassemble the chuck or handle panels as instructed in the user manual. Clean internal parts with compressed air and a brush. Reassemble once components are dry and free of debris.
Never submerge electronic parts or motor components in liquids. Regular internal cleaning can prevent overheating and mechanical failure.
Final Checks and Proper Storage
After cleaning, inspect your tools for signs of wear or damage. Reinsert fully charged batteries, and store your DEWALT combo kit in a dry, dust-free area, ideally in the included carrying bag. Keep batteries in a cool, dry place away from metal objects to prevent short circuits.
Perform this cleaning routine periodically, especially after heavy use or exposure to harsh environments.
