Wondering if anyone has figured out a better way to pre-treat on dark tri-blend t's. I know they are not the preferred blank, but we are having issue with a stained (discolored) type box that appears starched after we are finished. We have tried Brother pre-treat in dilution down as far as 2:1, and recently tried the Firebird 100 (which helped some of our problematic cotton shirt colors) but it was actually worse on the tri-blends.
Working with a Brother 381.
Thank in advance,
