As to the concerns raised by @Keith Lewis, here is a link to an article concurring with his statement about the phase out of that chemical by Home Depot - but read the link to get the full story.

If the bottom of the pile has organic matter or household chemicals or anything with moisture, it's most likely damaging the flooring and walls and attracting pests.

I later figured out that the soap/shampoo over time reacts chemically with the copper line and corrodes it.That is all I can come up with at the moment, but gives you a few more ideas before you open up walls.

I received a quote of $450 to use chemicals.

I honestly don't use the pool much, so I figured it might be a decent idea if I have to pay for heating it and the chemicals and everything anyways.

One month later, the bayou was dead, turns out the ground water was contaminated with PERK (dry cleaning chemical) that had been leaking for decades from a dry cleaner in the retail center.

Try Chemical Bank.

Is it synthetic stucco (many of the older ones had no drainage plane behind the synthetic stucco, so the structure rots)?

We close on it next Wednesday and I have done quite a bit of research on how to get out the smell.I purchased a product called " Mister Max Anti Icky Poo" weird name I know, but this is an enzyme that will break a lot of the chemical bonds in the urine.

At the end of the day, I have a degree in Chemical Engineering, so I will always have something to fall back on, so what is there to lose?
