I use Atsko sport wash on my jiu jitsu gi, and it is the only thing that gets the funk out and doesnt leave a perfume. I was practicing a lot last summer, and my saddle ended up smelling like my gi, which is to say like a dirty, sweaty locker room. My rope had gotten wet and not properly dried, and it too had a smell, but moldy. I made a solution in my slop sink of 1/4 cap full and water and let my saddle and lineman soak for a bit. They say it cleans off residue from dryer sheets and other detergents and helps the performance of technical fabrics. All I know is that it gets the fabric scent free with vegetable enzymes. It works for me.
Im not crazy into scent control, and play the wind, but removing strong scent from gear and clothing is a no brainer for me. My saddle was smelling so bad last August I could smell it in the hallway outside of the room I had it in. I started dipping and rinsing it every or every other use while I was dripping sweat practicing and in early season.
