What Can I Use Instead Of Dishwasher Salt?

What Can I Use Instead Of Dishwasher Salt? Substitutes: For dishwasher salt, use large grained “kosher” salt. For rinse, use white vinegar and for detergent, there are many natural recipes. I use two teaspoons of a mixture of half borax and half baking soda. If you buy tablets or powder, use half for each load.
