Great value for money

Very effective at removing stubborn stains from my printing glass. The only reason for 4 stars is the cap could be tighter.

Good but needs precise mixing

Works well if you get the dilution right. I made it too strong initially and it left a slight film. Follow instructions carefully.

Saved my prints

Had some old prints with hard water stains. This solution gently removed them without damaging the emulsion.

Essential for darkroom work

This concentrate works wonders on my developed film. No more water spots ruining my negatives. A little goes a long way.

Professional results

I use this in my photo studio for cleaning lenses and filters. It leaves absolutely no residue. Highly recommended.

Best spot remover I've tried

I have tried three other brands, and Shiguang is by far the most effective. My squeegee glides perfectly after application.

5 FAQ

Q: Can this be used on digital camera sensors?

A: No, this product is designed specifically for film, glass, and external optical surfaces. Please use a sensor-specific cleaner for camera sensors.

Q: Is this safe to use on coated lenses?

A: Yes, it is safe for most standard optical coatings. We recommend applying it to a microfiber cloth first rather than directly onto the lens.

A: When stored in a cool, dry place away from direct sunlight, the concentrate has a shelf life of approximately 24 months.

Q: How much water should I mix with 10ml of concentrate?

A: Based on the 1:20 ratio, you should mix 10ml of concentrate with 200ml of distilled water for optimal performance.

Q: Do I need to rinse the film after applying this?

A: Generally, no rinsing is required if diluted correctly. The formula is designed to air dry without streaks. However, always test on a spare piece of film first.
