Prepare the Salt Solution

  1. Measure enough tap water into the container to submerge your part completely and allow room for handling.
  2. Allow room in the container for the volume of salt and for the water that will be displaced by your part.
  3. For each 1 volume of water, add 0.7 volume of salt (see table below).
Metric Units Imperial Units
Water Salt
1 L 0.7 L
2 L 1.4 L
5 L 3.5L
10 L 7L
Water Salt
0.5 gal. 45 oz
1 gal. 90 oz
1.5 gal. 1 gal. 6 oz
2.5 gal. 1 gal. 96 oz

 

Note: If the amount of salt mixed in is incorrect, the salt solution may be too dilute and parts may become weak during spraying.

Tip: Using warm water helps the salt dissolve faster.

  1. Stir the water solution intermittently until the salt completely dissolves (5-10 minutes). If there are any undissolved crystals at the bottom, allow 1-2 hours to dissolve, and then stir again for 1-2 minutes.

    Note: Failure to dissolve all the salt could cause crystals to deposit onto your part when you dip it.
