Badly stained hot tub. It appeared to be mostly dirt with calcium hardness on top.
We always come across something different day-to-day. This one definitely was a little more challenging than it at first appeared. We thought a simple drain, acid wash and refill would take care of it. This actually required quite a bit of elbow grease.

It’s amazing how some jobs can surprise you! What seemed like a straightforward task turned into a real workout. It’s a good reminder that sometimes, even with the best plans, you need to be ready to adapt and put in some extra effort.
