I received this from mulberry
“Mulberry leathers are preserved using the most natural methods so the surface is not heavily coated.
The Collonil Waterstop spray is useful in protecting leather products against dirt and moisture, and may give some protection from external elements, although it will not make the leather fully waterproof. We would advise you applying this prior to use and keep topping it up on a regular basis.
After the Bag/purse have been used for a while we would recommended applying Collonil Leather gel. This is the best way to help protect our leather from the effects of weathering and UV damage, as well as moisturising the leather. Scratches and scuffs mark the leather easier when the hide is dry.
Natural leather does change in appearance over time and with use and you may find that the whole item will soften in colour as it gets older.”
Thanks! How often do you recommend using the spray?
