No, our cleaning agents have been specially developed for use at low temperatures. We never clean at temperatures above 30 degrees. Thus, there is no risk of shrinkage.
The following may occur with boat covers that have windows:
Window film may contract at temperatures below 15 degrees Celsius. This could be by as much as 1 to 3 cm at extremely low temperatures. Thus, it may appear that the cover has shrunk if you replace it during low temperatures.
Therefore, we advise replacing the boat cover only at temperatures above 15 degrees Celsius.
