I'm trying to line up all my chemical purchases for the darkroom. In perusing stop baths, I saw that Ilford makes one called "Ilfostop" which is advertised as "a low odor citric acid" stop bath, claiming to be "specifically recommended for dish/tray paper processing or tank professing of film". Doesn't seem to have any acetic acid in it, which means it can be shipped directly to me, as opposed to all the standard 28% acetic acid stop baths which have to be purchased in-store. Anybody ever used this Ilford stuff (or one like it)? I'm curious about its performance.
