Creases occur during the manufacturing and folding of the sunscreen cloth. A dark line may be visible in the folded area against the light, especially with light colors, which is caused by buckling of the fibre (light refraction).

This can occur along the side seams, in the area of the seams and in the middle of the webs. The fabric cover is doubled at the seams. This results in different roll-up diameters. The tension created by the folding arms, the tesioning system, the sagging of the winding shaft and/or the front profile can promote these effects. Ripples may also form if a "water pocket" has formed during heavy rain.

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

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