soft cloth, preferably after each use. Keep the
ventilation slots free from dust and dirt.
If the dirt does not come off use a soft cloth
moistened with soapy water. Never use solvents
such as petrol, alcohol, ammonia water, etc.
These solvents may damage the plastic parts.

essential. If the brushes have worn down
