In summer, people will choose to install shade sails outdoors. It is convenient for children to play outdoors to their heart‘s content, and it is also convenient for customers to rest outdoors, etc. Since the sunshade sail can be reused, people will put away the sunshade sail after summer. However, the surface of the sunshade sail has accumulated a lot of dust or oil stains after a few months of use. In order to better use the sun shade sail in the second year, the shade sails needs to be cleaned.
