I bought the 2-bottle set (10 oz. Tech Wash and 10 oz TX.direct) at REI and they were together in shrink plastic. When I took them out of the plastic I realized there were no instructions on either bottle on how to use the product. A quick web search took me to the nikwax sight and instructions for the TX.direct stated "Run 30° synthetic cycle and slow spin." My washer doesn't have a 30 degree cycle (does yours?) and doesn't have a synthetic cycle and doesn't have a slow spin. I just washed the coats on gentle cycle and let them sit for about 30 min before rinse. Seemed to work ok. For such a "tech" product the instructions seem obtuse.
