Claire N. ★★★★★ Oct 22, 2026

Mixing this up was way easier than I thought—the 1+19 dilution is straightforward, and the fact that it doesn't smell at all is such a relief compared to my old stop bath. The indicator dye shifting to yellow is a nice touch for knowing when it's done.

Finally, a stop bath that doesn’t smell like a chemistry lab. I love that the indicator dye lets me know exactly when it’s exhausted, so I’m not guessing. Mixed a 1+19 batch and it worked perfectly for my latest prints.

The indicator dye turning yellow is really handy for knowing when to swap batches, and the lack of odor makes a noticeable difference in a small darkroom. I just wish the 5L jug came with a better pour spout.
