7Cleaning the system

Stains on the system should be wiped off with a soft cloth. If the system is heavily stained, wipe it with a cloth soaked in water- diluted neutral detergent and wrung well, then wipe clean with a dry cloth.

DO NOT wipe it with a hard cloth.

DO NOT wipe it strong.

DO NOT wipe it with thinner or benzine.

DO NOT apply any volatile substance such as insecticides to it.
