Washing and maintenance

Open all panes. Clean the uppermost pane from the outside. Slide the panes one by one onto the sliding bead. Wash the pane from the inside. Wipe the aluminium parts with a damp cloth; use ordinary domestic detergents. Lubricate the plastic parts once or twice a year with silicone oil.

Note! When cleaning coated glass panes, be careful not to scratch the surface. Lubricate the Activ glass panes with Teflon-based lubricants; do not use silicone-based products.
