Suede and leather goods don’t require any special treatment. True -they don’t like water but it doesn’t mean that a few drops of rain will hurt them : )
If you want to ensure any dust and liquids won’t reach them, you can use a special impregnate-spray from time to time. You must also remember that any stains must be removed with a special suede-rubber (not water). If the stain seems serious it’s always the best to contact you local leather goods repair shop.
Some of our backpacks and bags are finished with handmade brass elements. Brass oxidise over time and it slightly change the colour to more orange-gold and more matte finish. If you wish to refresh the colour of the brass you can simply use a clean cloth with a bit of a toothpaste and gently rub the brass handles.
