I love my jet tub, but it wasn't draining. So I tried baking soda, vinegar, and hot water. It still wasn't draining. So I used a drain cleaner. In a little while we put the rest of the drain cleaner in and that worked. So I was in the bathroom a pretty good while. I scrubbed the tub with baking soda, since I had it in there. That looked nice. Then I took a brush to the stopper. Gross stuff popped off of it. Then I ran a tub full of hot water, put a cup of vinegar and a dishwasher tablet in and let it run for ten minutes so the jets would be clean. Then I refilled it with hot water and let the jets run again so the pipes would be rinsed.
Then, one more pass with a magic eraser and vinegar.
