The clearing bath quoted earlier in this thread works fairly well. Amazing to watch the wedge go purple in the 1st bath and then raidly clear in the last, leaving very little stain behind. The RC paper I used seems to hang onto a faint yellow even cleared twice. The relief is very fragile in there and is prone to rubbing off/dissolving away so times quoted are probably the maximum. I will post a cleared wedge when it is dry.
PS Stick to the times for each bath, 1 minute, no agitation required I dont think, dry before washing I think or the highlights will wash away. Any residual yellow stain goes with the wash water. Its possible I am using the wrong concentration Sodium Sulfite, I am using anhydrous.
