Picked up a used Marquis Spirit the other day. It was filled, heated and running when I went to look at it. Everything worked fine, but I noticed a white ring around the entire tub. I was able to scratch off the residue to expose the acrylic surface underneath. I am not sure if is chemical residue or minerals from the water. The woman who sold it to me was not sure either. She had bought the house and didn't use the tub. It sat for over a year. The electric was on and the tub did run every 4 hours. The cover was shot though. I drained the tub before transport. It rained the other day and the tub had a few inches of water in it.
I was going to go to wall mart and get a hard water remover, but after reading this forum I figured I'd consult an expert. I went to the local marquis dealer and he sold me a cleaner called Robarb Clean-A-Way and a scouring pad. He told me that I should not use anything stronger than this. I scrubbed for a few hours and got a good deal of the redidue off, but I still have the "Ring around the Collar" I am able to remove the residue with a screwdriver, but I know this isn't the way to go either, besides it would take a million years to get into all the nooks and crannies (What is a cranny anyway?) Any suggestions?
BTW. I looked in the chemicals she had given me with the tub and guess what was included? Good old Robarb Clean away and some metal stuff that I also bought from the dealer. Shucks! No big thing, I needed to make friends with him anyway.
Once last thing I thought you might find funny. While looking at the spa I had opened the cover to make sure everything was on the up and up. I went with the woman into her house to trip the breaker so I could look at the electrical panel in the spa without getting zapped. We were gone for 15 seconds tops! When we came out, her middle daughter (8 Yrs old ) had jumped in the tub with all of her clothes on. It was hysterical! The woman didn't find it funny though? "See why I need to get rid of this thing!"
Anyway,
any suggestions you have will be greatly appreciated.
