If you have chosen classic vinyl solar shades your work will be easier. Just use a damp cloth or a sponge with a little lukewarm water and mild dish detergent. You need to wring out the cloth or sponge. Then, gently run over the canvas to dislodge the dirt. It's that simple!
If you are cleaning solar shades, the best way to clean them with a cloth or sponge is to start at the bottom and work your way up. It is better to make small section and rinse with a damp cloth without detergent. Continue until the fabric is completely cleaned.
After cleaning and rinsing, the blind should be dried to prevent dust from sticking to your window coverings. To do this, use a hair dryer set to the lowest heat. This will help you loosen the excess water trapped in the micro-covers of the fabric.
