• clean dirt with warm soapy water; do not use solvents or abrasives and do not wipe the window dry;


• wipe the seals with a special silicone lubricant to preserve their function;


• lubricate the moving hardware parts with a special oil twice a year;


• if the sash becomes harder to close, the window can be adjusted — better to call a specialist;


• do not wedge the sash with foreign objects — this damages the window.
