Deposits such as leaves, fibres... etc., must be used with a vacuum cleaner (use a brush or a spray, carefully avoiding rubbing with metal parts or abrasives). If compressed air is to be used, ensure that the air stream is kept pointing perpendicularly to the surface of the battery to avoid bending the aluminium fins. Take care not to bend the fins with the nozzle of the compressed air gun. b) Rinse with water. Chemicals may be used (specific products for finned batteries). Rinse it by running water through each of the finned passages until they are completely clean. Ensure that the water stream is kept pointing perpendicularly to the surface of the battery to avoid bending the aluminium fins. Do not touch the evaporator with the end of the water inflow hose. It is recommended to limit the pressure of the jet so as not to damage the fins by putting your finger on the end of the water inflow hose.
