Bleche White is basically sodium metasilicate solution (an inorganic soap) with some bluing. Blue makes yellow look white and was used in washing clothes and still is.
You can buy uncolored concentrate under many names. It typically comes in 50% concentrate in drums, I believe, so you'd have to clean alot of white walls. Check with a local chemical supply house that sells smaller amounts. I had bought some from a guy going door to door but it was pricey. Have to cut 50% to about 5% with water for WW. ~10:1 Don't mix it too much it'll foam up.
BW got pricey after Black Magic bought them out and was hard to find for a while. To my knowledge they stopped selling in the gallon refills, at least around here. Have to pay for the buy out some way through the customers...
