Customer Reviews (4.8 / 5 · 5 reviews)

Grace ★★★★★

The instructions said to bleach then wash for 10-15 minutes before redeveloping, and even my most overdone, dense negatives came back with perfectly manageable contrast. I've only needed a tiny amount each time, so the 500ml bottle feels like it'll last me years of darkroom work.

Matthew ★★★★★

My over-developed negatives were basically hopeless until I tried this bleach—the way it reduces lith contrast is exactly as described. The 500ml bottle is plenty for my 35mm rolls, and the 10-5 minute wash after bleaching made a noticeable difference in the final prints.

Natalie ★★★★★

Finally, a reliable way to salvage over-developed negatives without harsh contrast. The process is straightforward—bleach for the right time and redevelop—and it saved a roll I thought was ruined.
