My spa has some stains, not horrible but noticeable and livable. I am not sure what these stains are made of..they are caramel colored, brownish (I'll get a picture soon). I had been thinking about draining my spa and doing a very light acid wash on the marcite....like 20% MA and 80% water. Spray/brush and refill the spa.
Interestingly....the other day I had a nutrient "Nature Valley brand" Potassium pill that I forgot to take (helps with muscle cramps) ...it was in my Tee shirt pocket and the pill fell into the Spa seat/sitting level when I was putting the shirt back on. I saw it the next day....it was 90% dissolved....and for about 6 inches around the pill remnants in all directions the stains were gone. Whoa?
Interesting...Potassium stain remover? Hmmm, maybe I'll try it again...put a few in a sock?
Any problem with Potassium in the pool? I'll check the label for the milligrams amount.
