Hi PackardV8,
According to a poster in the Cadillac-LaSalle Club Forum from back in 2007, Bleche Wite actually contains no bleach. It uses sodium metasilicate, an alkaline chemical with a pH of 13. This is used in cleaner/detergent formulations, mainly in industrial applications. He further states that a potential replacement is TSP, trisodium phosphate, inexpensive and available in hardware stores. This is used to clean exterior house paint before repainting, and a few tablespoons in a quart of warm water will clean almost anything. He recommends wearing gloves and using Brillo or a similar scrubber. Note that other posters say Brillo and such products roughen the whitewall surface and effectively turn the whitewalls into dirt magnets. So it's a very tough call on this.

I'm satisfied by using Bleche Wite with a common household scrubbing brush with some kind of plastic bristles (nylon?). I don't think the brush roughens the whitewalls to any great extent if at all. I wouldn't use steel wool as I've found that that can leave tiny amounts of itself on the tire and it soon shows rust spots.
