At last Gilles et Chantal are over to visit our house and to discover London…last visit was probably when Jules was born so close to 20 years….
Because I cannot find “Lessive de soude” (a 30% Caustic Soda or Lye mixture). I am trying to use Baking Soda which is also a higher PH.
Lessive de soude at 30% (as you purchase the liquid bottles in France) is usually PH14.
Baking Soda of 3 Table Spoons in 500ml of water PH9.5 (I have measured this ). So I am using that to take the bitterness out in the initial soak.
