I called from Maryland about our spa & pool in Kissimmee. The spa was completely stained with rust from the previous owners and we have our first renters in 2 weeks. I was so worried that they would be horrified that the spa looked dirty. [Kissimmee Pools] went out the very next day did an acid wash to the spa & to a couple of spots in the pool. They sent pictures and it looks great!!! Thank you so much.
