I use this product to wash ALL my nylon or poly cycling jerseys - esp in summertime. First time I used it the water turned gray gray gray. I thought all the color was coming out from the garment. But it was dirt, buildup detergents and probably dead skin. The colors were NOT bleached, maybe even brighter (this jersey had lots of red and black). AND it smelled sweet again. Be careful to not use too much in the water - it can leave a "dry cleaning" smell. Use about 1/2 recommended amt and garment will be clean and restored to brand-new condition. The wool base cleaner is just as awesome - on woolen garmets.
I bought this product to remove an odor from my sandals. The sandals became so foul smelling last year that I couldn't stand to wear them. I had already tried washing them with regular detergent multiple times, and waiting a week or two for the smell to subside, the smell got a little better, but there was still a lingering odor. I ordered basewash and used it on both pair of sandals and it worked as advertised. The odor was completely gone and has stayed away for about a month now. I've used it on my Arc'teryx base layers and UnderArmour charged cotton shirts with equally impressive results.
