Welcome to our forum.
I had the same problem this weekend. The mother-in-law was over and we in in for about 3 hrs. I think she had a ton of lotion on and two days later there was oily crap in the suds all over the place. It was so discusting. I added everything in the kit to try to clean it up and said the heck with it. Drained it, wiped it out and started over. Everything is fine now.
