I recommend that nothing but liquid touch wet film: no squeegee. I do the final rinse in distilled water and photo-flo 3 drops per 8 oz. Don't store diluted photo-flo, it develops scum. For rinse water I fill a large container (1/2 gal) from the faucet, adding hot or cold to adjust the temp. Then I dip out of this to rinse the film. No concerns about the temp varying out of the faucet. Refill the container as necessary.(posted 9291 days ago)
