Washing for bread with salt water

Hi,

The water used for washing before bread must be potable, at least to the point that a dog would drink it. If it is salty, smelly or bitter to the point that a dog would not drink it, one may not use it to wash for bread.

(Shulchan Aruch Orach Chaim 160:9; note Mishneh Berurah 160:38 on desalination)

Have a great day,
Mordechai
