You can take the rice out after the salt dries out if you’d like, but most restaurants and people that do this leave the rice in the salt shaker. It doesn’t appear to impact the salt at all and the rice rarely absorbs enough moisture to go bad. How long it takes the salt to dry out depends on a variety of factors. You may notice the salt dry out overnight, or it may be a few weeks before those obnoxious clumps dissipate. You can add more rice if you have a bunch of salt or its really wet. The wetter the salt is, the more it’ll benefit from a large amount of rice. It will be a pain to remove the rice, so this works best if you’re using a salt shaker. The large grains won’t come out of the holes at the top of the salt shaker.
When you turn the salt shaker over, the salt will spill over around the edges of the paper towel. It may be a little harder to sprinkle the salt, but you’ll still be able to use it just fine. Replace the paper towel every 7-10 days to make sure it doesn’t get too moist.
Replace the coffee beans when you get to the bottom of your container. When the salt is dry, you can transfer it back into a salt shaker or simply leave it in the new container.
Replace the kidney beans every 3-5 days. You shouldn’t have much of a problem scooping the beans out with a spoon. If they’re coated in sticky salt when you remove them, it’s a sign that they’re doing a great job of absorbing water. If you’re dealing with clumps on the surface of the salt, leave the kidney beans on top of the salt and don’t mix them in. Kidney beans have the ability to remove moisture from the air, which may be your main problem.
Replace the parsley leaves when you get to the bottom of the salt shaker. You can use cloves instead of parsley if you prefer. Both cloves and parsley will lift moisture out and infuse your salt with a delicious scent. [6] X Research source
Replace the soda crackers every 10-15 days to keep them from rotting in the salt. To do this, use a pour the salt over a strainer into a fresh container to filter the crackers out.
Grinders typically let a little bit of moisture in, but the blades are designed specifically to break salt rocks up, so this shouldn’t be a problem for you.
Salt absorbs water from the air in a cumulative kind of way—once the salt starts absorbing moisture, it will pull more and more of it out of the air.
