The MSDS is very long, here’s a more succinct version. 0.5% is the recommended dilution for safe but effective use.Why do you dilute it so much? Why not go stronger ?
or why not just spray the hell out of them with sawyer's ? until they are dripping wet.
and why spin in the washer? why not hang dry ?
You can spray the hell out of your clothes with Saywers version but it’s more expensive than mixing your own. $12 for 8oz of Martin’s makes 160oz (over a gallon) diluted vs $20 for 24oz of Sawyers.
I just think soaking impregnates the fabric more effectively. Spin cycle in the washer to get most of the water weight out before hang drying. Don’t want the merino tops to stretch under their own weight. Or the weight to rip my shower curtain rod off the wall.
