AeroCover Tips: Due to temperature differences, condensation is inevitable. AeroCovers help to transport moisture to the outside. Make sure that you create adequate ventilation to allow the cover to breathe. Never lay the cover flat on top of your grill. Make sure the cover and the BBQ have some space in between, for example by placing a bowl, ball or bucket in between. In the same way, always create a highest point so that water can slide off the sleeve and no water remains on top of the cover. Regularly open and check your BBQ when using it for multiple days without taking it off. Make sure your BBQ is dry before covering it to prevent the formation of corrosion on your grill. AeroCovers® have a high color fastness, are breathable, water-resistant and are there for the best protection for your valuable BBQ grill.
