Do not directly spray your power meter with a pressure washer.
Cover your power meter to avoid direct contact with any cleaner/degreaser. Some degreasers can cause your battery housing to become brittle. If you get cleaner/degreaser on your power meter, make sure to rinse it off immediately.
Take the battery cover off when dry and wipe down the gasket area with a dry paper towel to ensure that no cleaner/degreaser has gotten in between the gasket and fasteners.
