Cleaning exterior roller shutters sounds like a simple job. Water, a cloth, a little patience and done. At least in theory.
In practice, it very quickly turns out that roller shutters are not as easy to clean as they might seem. Especially when they are fitted 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 appears: are traditional methods really enough, or is it better to use a solution created specifically for this task?
