7.1 Cleaning SP-20 tiles
Why clean SP-20 tiles?
Due to outdoor use the SP-20 tile is exposed to all kinds of weather conditions. Sand, dust, smog and other dirt adhere on the SP-20
tile and therefore the visual performance of the SP-20 display is reduced. That’s why cleaning the SP-20 tiles is recommended at
regular intervals.
Necessary tools
• Vaporizer with a window cleaning product.
• Soft hand brush with long hair (recommended 4 cm pure pork hair).
• Garden hose with a spray nozzle.
• Compressed air.
