Gazebos aren’t too hard to clean to be honest. It’s more hassle than anything, but in terms of accessories needed, you only need the basics – detergent, sponge, soft haired broom, hose.
Before you start, fill a bucket with warm water and add some detergent. Of course if your canopy is extremely dirty, then add more detergent and mix till it’s formed completely.
Dip the broom into the soapy water and scrub gently to remove the build-up of dirt. If the dirt is stubborn, then scrub with a sponge. After your cleaning is done, rinse the cover with a hose and remove all signs of detergent residue.
