No more re-washing

Previously I had to re-wash films multiple times to get them clean. This solution cuts that time down to seconds. Highly recommended for high-volume developers.

Good economy pack

Two bottles last a long time since you only need a small amount per batch. Removed some old sulfur staining from a batch of archival film successfully.

Easy to use for beginners

I was worried about messing up my first roll of developed film, but the instructions were clear. One dip and the water sheets off perfectly.

Essential for professional results

Using this as a final wash promoter has significantly reduced my drying time and eliminated streaks. Great value for a two-bottle set.

Saved my negatives from hard water spots

I live in an area with very hard water, and my films always came out with annoying spots. This remover worked perfectly after a quick soak. The negatives are now crystal clear.

Effective but strong smell

Does exactly what it says regarding sulfur and water stains. Just make sure you have good ventilation in your darkroom as the odor is quite potent during mixing.
