Your Carqon Box Cover is waterproof, so clean the cover by hand with a bucket, a sponge, a hose and mild soap free from strong chemicals. Put pressure on the dirty spots to clean the cover. 

• Check the weather forecast and pick a day without heavy rainfall, so the material can dry.
• Don’t use bleach or other chemicals.
• Don’t use a pressure washer.
• Don't use too much water on the cover, for example emptying a full bucket of water, as the pressure on the cover might become too high. 
• In case of using extra pressure while cleaning, it's better to remove the cover from the box.

Note: Prior to cleaning or servicing, secure all moving parts of the cargo bike.
