Step 1: Choose a container
A clean glass, small bowl, or even a breathable fabric pouch will work. Avoid sealed containers—salt needs to interact with the air.
Step 2: Fill with salt
Use about one cup of salt (table salt, coarse salt, or rock salt all work).
Step 3: Place it strategically
Set the container in your car overnight or keep it there during damp seasons. Popular spots include:
-
On the dashboard (away from direct airbag zones)
-
Under a seat
-
In the trunk if you store tools or gear prone to rust
Step 4: Replace as needed
Over time, the salt will clump as it absorbs moisture. Replace it every few weeks, especially during rainy or snowy months.
