i spray my 3 pairs every 3 times i wear each. or if its raining, just before i go out in the rain.








p.s. i know it says on the bottle to let them dry for 24 hours, but if you just let the sit for 10 min, they will be fine.How often do I have to spray my UGG boots with the water and stain repellent?
