Nikwax Footwear Cleaning Gel - Breathable waterproof footwear is most likely to get sweaty and wet inside when used in damp or wet conditions. If the outer fabric or leather absorbs water, the breathability of the footwear will be reduced. Therefore, the Durable Water Repellency (DWR) of your footwear must be maintained to ensure comfort. Through use, the outer surface of footwear will pick up contaminants, such as dirt, which attract water, masking the effect of any DWR coating. Nikwax Footwear Cleaning Gel will remove contaminants and revitalise DWR.Nikwax Fabric & Leather Proof - Your footwear could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Footwear Cleaning Gel, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalised just from cleaning. But, once the footwear has been thoroughly worn you will need to add DWR, using Nikwax Fabric & Leather Proof, after cleaning first with Nikwax Footwear Cleaning Gel.
