I recently saw a car being detailed, they were using APC (all purpose cleaner) and brush.
The amount of cleaner being sprayed and brushed around switches sent my mind thinking.
Lots of car owners have reported malfunctioning power switch and parking brake switch.
If this liquid gets into the switch it can damage the circuitry ..
Please avoid spraying liquids on & around switches.
Only spray lightly on microfibre cloth and wipe the switches if required.
