CHẤT LÀM SẠCH HYPO CHUYÊN NGHIỆP, Dạng bột cô đặc pha 5 Gallon

The powder dissolves fast in warm water, and the mixed stock solution has been sitting on my shelf for a month without losing strength. Washing times for my fiber prints dropped noticeably, which alone is worth the extra step of mixing it up.

I’ve been using this to cut down my film washing routine, and it really does the job—one batch of stock solution goes a long way since it makes a full gallon before dilution. The powder mixes clear with no residue left in the tray, which I appreciate.

The powder dissolves fast enough that I had a working stock solution in under five minutes, which made the whole gallon mixing process painless. It cuts my film washing time down to a few minutes instead of the usual rinse cycle, and the prints have stayed clear and evenly fixed.
