Thank you for your enquiry.
Firstly, make sure the boots are dry. Then use a suede brush to brush off any dirt. If the stain is wet, use a cloth or paper towel to pat dry. For water spots or scuffs, gently rub an eraser over the affected area. For real stubborn stains you can use a suede cleaning product or white vinegar. Simply apply a small amount to a damp soft cloth. Rub on the stain until it is gone. After the stain has been removed, blot the area dry with a dry cloth or paper towel. Once the boots are dry, brush the nap and they'll be as good as new.
You can also pre-treat the boots with a waterproof spray which can be readily purchased.
I hope this helps.
