Contamination of the plug may cause fire due to conductivity, so pay attention when using your mobile phone or hair dryer every day. What about the plugs of washing machines, TVs and other electrical appliances that are not frequently plugged in and out? How to clean the plugs if there are dust and hair on the plugs? ▸ Turn off the power before cleaning. ▸ (You can wear rubber gloves) Use a cotton swab, paper towel to remove dust or wipe it with a dry cloth. ▸ Do not touch the red copper sheet in the socket when wiping. ▸ Do not use a damp cloth to avoid electric shock. ▸ Install the socket in a damp area to prevent moisture. Regularly check the electrical appliance's plug (socket) for embroidery, blackening, dust accumulation, and clean and wipe it. Kick off the little devil who may cause a wire fire!
