Cleaning exterior roller shutters sounds like a simple job. Water, a cloth, a little patience, and done. At least in theory.
In practice, it quickly turns out that roller shutters are not as easy to clean as they might seem. Especially when they are installed high up, next to large glazing, on FIX windows, or in places where access from outside is simply difficult.
And that is when the question comes up: are traditional methods really enough, or is it better to use a solution created specifically for this task?
