Detailed Answer
Cleaning methods: 1. Housing: wipe with a slightly damp soft cloth (clean water only; no solvents/alcohol); 2. Keypad: use compressed air/soft brush (compressed air for dust); 3. Battery contacts: dry cloth/cotton swab (eraser for oxidation); 4. Charging contacts: gently wipe with a dry cloth; 5. Vent membrane: brush gently with a soft brush (do not poke). IP67 models (Lider LD series) can be rinsed with low-pressure water and then dried. Turn off the remote before cleaning.
