It’s quite simple to clean outdoor roller shutters. Firstly, dislodge any loose dirt or debris using a soft brush or vacuum cleaner. Then, prepare a gentle cleaning solution of water and mild detergent and use a sponge or cloth to scrub the shutters. A bit of vinegar added to your cleaning mixture could work for more stubborn blemishes. Follow up by rinsing with clean water and drying with a soft cloth. Regular cleaning ensures your roller shutters stay good-looking and function optimally.
