"I couldn't find anthing that was just H20 and NaCl."

My home remedy for saline is approximately 8 oz H2O, 1/8 tsp of baking soda, 1/8 tsp of table salt.

Admittedly this is my home made saline remedy for clearing my sinus passages but should translate to a stable cleaning solution for wounds. it mimics sea water but the soda cuts the harshness of the NaCl.
