Nikwax TX 10 Cotton Proof
Nikwax TX.10 Cotton Proof is the easy to use, safe, high performance, wash in waterproofing for cotton, polycotton and canvas.
Your cotton items could be soaking up water just because they are dirty.
First, try cleaning them with Nikwax Tech Wash®, and if they are fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalised just from cleaning.
But once items have been thoroughly used, you will need to add DWR using Nikwax Cotton Proof™, after cleaning first with Nikwax Tech Wash®.
