Creases occur when the awning fabric is made up and folded. At the folded point, a dark line may be visible against the light, especially with light colours, which is caused by the folding of the fibre (light refraction).

This can occur along the side hems, in the area of the seams and in the middle of the panels. The fabric is doubled at the seams. This results in different roll-up diameters. The tension created by the articulated arms, the tensioning system, the sagging of the winding shaft and/or the delivery profile can favour these effects. Ripples can also form if a "water pocket" has formed during a heavy rain.

Awning fabrics are impregnated with a water repellent finish and will remain rain resistant during a short period of light rainfall when used according to the manufacturer's instructions and at an angle of inclination of at least 14°. During prolonged periods of wetness and/or heavy rainfall, the awning must remain closed or retracted to prevent damage. Once the fabric has become wet, the awning must be extended again to dry immediately after the rain to avoid mildew stains.

The fabric is usually kept under almost permanent tension by an active spring system. Seams and hems act as reinforcements, but must also withstand the greatest stress. When the fabric is rolled up, the hems and seams lie on top of each other, which increases pressure and tension even more. This puts them under extra stress and stretches them. This can cause the side seams to hang down slightly when the awning is extended.

Dust can be removed with a soft brush when dry. Leaves and similar soiling should be removed immediately. Small stains should be removed with water and a commercially available, preferably liquid, mild detergent (5 percent soap solution, water temperature max. 30 °C). Rinse thoroughly with water.Detailed instructions with all important instructions for operation, care and maintenance are enclosed with every awning delivery.
