The risk of using household (Dishwashing liquid) or personal care products (Handwash) is that perfume aside, they contain shedloads of salt to thicken them, and the surfactants commonly used will often dry down to a sticky / greasy residue. The only household product that would possibly work is shower spray. This is the stuff that you spray on the inside of a shower door to prevent water marks and staining. That works like photoflo, and is probably very similar.
I don't use photoflow, however. I use Ilfotol instead. Same sort of thing, easier to get locally, works in the same way.
The shower spray that contains Sodium Hypochlorite will dissolve the emulsion completely and leave a mess behind! Don't ever use that.
Would that be one of the chemicals you can measure with a teaspoon??
At one time, the cap of the Photo Flo bottle was its "measuring spoon" and the instructions called for one capful in a quart (or gallon, I forget) of water. This was so long ago. My goodness, I used to use it with the TriChemPak and with Versatol. So there!
