Ceilings generally require very little maintenance as the surface is well protected from mechanical damage. Normally the biggest problems come from dirt and dust circulated by air currents from the ventilation systems. Loose particles such as dust and dirt are most easily removed by vacuuming the surface with a soft nozzle. More stubborn stains can be removed with a special type of stain-removing sponge. As a rule, you cannot wash the surface with detergent or rub off stains and dirt with a cloth or ordinary sponge. The earlier you act, the better the result will usually be. Therefore, expect a seamless acoustic ceiling to require a maintenance schedule that includes light cleaning a few times a year. If you need help creating a maintenance schedule, just contact us.
