Table Salt vs. Pool Salt

 In Pool Salt

Many people will likely be surprised to learn that table salt, often referred to as regular salt, actually has quite a bit in common with the salt used to keep swimming pools clean. Here are some other similarities and differences found between pool salt and regular salt.

Pool Salt

Some swimming pools are kept clean by using salt instead of chlorine bleach. The type of salt used for pool cleaning must be 99.8% pure food-quality salt. Unlike table or regular salt, pool salt does not contain any anti-clumping agents. Neither does pool salt undergo the iodization process, consisting of spraying table salt with a tiny amount of potassium iodate. While many people have probably assumed that table salt is the purer between the two, in reality, pool salt is likely even purer than table salt.

Table (Regular) Salt

This is the salt that people use to cook with and to flavor their meals. Table salt commonly comes in two forms; iodized and plain. Many table salts include potassium iodate to help individuals avoid becoming deficient in iodine. Anti-clumping agents are typically added to iodized salt since the added potassium iodate can cause clumping. Some cooks use non-iodized (plain) salt for pickling or brining food items since, over time, iodized salt can oxidize and cause the color of foods to darken over time.

    Switching from Chlorine Bleach to Salt

    Once people understand that pool salt is virtually identical to table salt, it becomes easier to consider in regards to pools. When it comes down to salt and chlorine, salt typically wins. Chlorine bleach can burn the eyes during swimming, and it tends to irritate and dry the skin as well.
