I've used Orbit Bath for about 30 years, but I've used it as if it was ordinary HCA, which is what it is. That means I give two or three minutes for film followed by a 20-30 minute wash and 10 minutes for paper followed by a one-hour wash in a decent washer. I just use Orbit Bath for convenience rather than mixing powder since I use a lot of HCA.(posted 8359 days ago)TKO has published those wash claims on the bottle for all this time but so far as I know has never made available any supporting evidence or documentation.
Somewhere or other I saw an MSDS for it; it contains sodium sulfite and sodium bisulfite...aka HCA.
