Mix 1 part of vinegar with 3 parts of water in a spray bottle. Depending on the levels, you should wait for several hours to get in the tub. If your hot tub smells like chemicals, it's most likely due to a lack of sanitizer.

Make sure you don't touch the testing area if you've got wet hands from the hot tub water as this could make the test pointless. If the levels aren’t ideal, adjust the hot tub water as needed. Chlorine should be at least 1.
