Every strap is sealed with a tough, transparent wax, making it very dirt-resistant. This means that it always performs well, even in extreme conditions, and very rarely requires any maintenance.
There is generally no need for special care; if it gets wet, the strap can simply be dried at normal room temperature (15-25° C). However, heat sources such as radiators and hairdryers should be avoided.
Dirt can be rubbed off easily with a soft cotton cloth. To remove stubborn grime, use a soft brush – or, if this is not enough, spray the strap lightly with cold water and rub dry with a soft cotton cloth.
