TX.Direct® Wash-In 6 The No.1 easy to use, safe, high performance wash in waterproofing for wet weather clothing. Adds Durable Water Repellency and revives breathability - in a washing machine. Your raingear could be soaking up water just because it is dirty. First, try cleaning it with Nikwax Tech Wash®, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalized just from cleaning. But, once the garment has been thoroughly worn, you will need to add DWR, using Nikwax TX.Direct®, after cleaning first with Nikwax Tech Wash®.
