Nuclear fast red is a dye that will eventually go out of manufacture, and certainly if you're having trouble with it you need to be looking for an alternative.
Anatech has been offering brazilin, a natural dye very similar to hematoxylin, except that with an alum mordant it's red rather than purple. They offer both the dry dyestuff, and a ready-to-use solution called "Brazilliant". I haven't seen this dye in action, and I'd like to know what results people are having with it. There is one problem on the horizon: unlike logwood, which is an invasive species in the Caribbean islands where it was introduced from Mexico, brazil wood is supposedly an endangered or threatened species. (I have no commercial connection with Anatech.)
