Review on 🌧️ Grangers Performance WASH: Top Choice by Global Leaders in Extreme Technical Outdoor Wear. Perfect for All Breathable Membrane Fabrics, like Gore-Tex and Event. by Cee Pouncy

I just used the GPW to clean the oil/grease that dripped from the chairlift cables onto my new bright orange parka during a wet snowstorm in Mammoth. I didn't know how bad it was until I got home. There were small black dots on the hood, back and shoulders. I used GPW directly undiluted with a toothbrush and let it sit for about 1 hour before washing. I did 2 wash cycles, one with GPW and the other with just water to fully rinse. Hang to dry. The stains came out really clean. Most are 100% gone and only a few I can barely see within an inch or two. Worked great for me and will use again.
