How to Wash a Milwaukee M12 Heated Jacket

Step-by-step instructions

Step 1: Match the series number to its washing instructions

Find the garment’s model or catalog number, not just the M12 logo on its battery. Milwaukee’s 232 Series jacket manual specifies a warm gentle machine wash and low tumble heat. In contrast, the 2334, 2337 and 2346 Series manual requires cold hand washing and hang drying. A machine’s hand-wash setting does not satisfy that older instruction. If your series is different, obtain its own manual; a shared battery platform does not make the textile construction identical.

Step 2: Switch off and remove both removable electrical components

Turn the jacket off, disconnect its power cable from the holder or controller, and remove the controller and battery pack from the garment. Empty the other pockets as well. Keep these parts away from the basin and laundry basket so they cannot accidentally enter the wash. Removing only the battery but leaving its holder in a pocket is not enough. The charger also stays dry and separate. Do not cut seams, remove heating panels, or try to pull the permanently attached wiring out of the jacket.

Step 3: Inspect the fabric and secure the loose cable

Check the liner, seams, cable and pocket for damage before laundering. A torn wire, exposed connection or malfunctioning switch needs attention rather than another wash. For the machine-washable 232 Series, push the garment’s attached cable completely into the battery pocket and close it as directed. Make sure the zipper is not trapping the cable. Follow your own series’ pocket and closure directions if they differ. Remove sharp pocket contents such as screws or pins that could snag the fabric or damage the heating system during handling.

Step 4: Wash by the permitted branch, without stronger substitutes

For a 232 Series jacket with matching instructions, use warm water and the gentle cycle. For the listed older hand-wash-only series, use a clean basin with cold water and gentle handling instead. Follow the detergent’s garment-compatible dose rather than adding extra for workwear dirt. Do not use bleach, dry-cleaning fluid or a dry-cleaning service on these jackets. Avoid turning stubborn grease removal into an experiment with solvents: Milwaukee warns that cleaning solvents can affect heating-element insulation, even when the outer fabric looks unharmed.

Step 5: Rinse and handle the wet jacket without twisting

Complete the normal rinse for the approved washing method and inspect cuffs, the lining and pocket folds for remaining suds or debris. Support the wet garment while moving it; do not use the power cable as a handle. Neither cited manual permits wringing, and the 232 instructions also prohibit twisting. If a mark remains, assess whether further label-compatible washing is worthwhile before repeating the process. Do not scrub into a heating panel with a hard tool or use a concentrated stain chemical simply because the first wash left a shadow.

Step 6: Dry according to the same series, not another jacket’s label

The 232 manual allows tumble drying with low heat. The cited older series must hang dry and must not go into a machine dryer. Keep these branches together: choosing the older jacket’s wash method does not grant permission to use the newer jacket’s drying method. Do not iron either series, including a wrinkled collar or logo. Check the lining, thick seams and battery pocket, not just the outer shell, before deciding the jacket is dry. Do not connect its battery to use the heater as a drying aid.

Step 7: Reconnect only after drying and check normal operation

Once the garment and connector area are completely dry, inspect them again for damage and reconnect the correct controller and battery according to the manual. Keep the cable clear of the pocket zipper and avoid crushing it while closing the pocket. If the jacket fails to work normally, stop using it rather than repeatedly cycling it while damp or pulling at hidden wiring. Store it dry with the battery disconnected. Retain a photo of the care label so future washing follows the same verified instructions even if the printed tag fades.
