If you’re ever cleaning a hot tub, it’s a good idea to use vinegar as a cleaner. Vinegar is a great choice because it’s non-toxic and it can clean the jets quickly and easily. To clean the jets, first pour some vinegar into a small bowl. Then add enough water to cover the jets. Let the mixture sit for about 10 minutes, or until the vinegar has worked its way into all of the jets. Finally, use a plunger to push all of the vinegar mixture out of the way and replace any dirty jets with fresh ones.
