Pro 2-in-1 Clean and Proof 5L Offering the complete aftercare solution in bulk form. Grangers Wash and Repel Clothing 2 in 1 is now available in 5L, so you can clean and reproof several items in one wash cycle with this larger capacity product. This wash-in cleaning and waterproofing treatment ensures your gear is clean and protected against the elements, so everyone can stay protected, whatever the weather! It's important to take care of your gear, and waterproofing dirty clothing just really doesn't make sense. It won't perform as well, it'll affect breathability and it won't look the part.
