Dangers just outside your doorAntifreeze that contains ethylene glycol has a sweet taste that attracts animals but is deadly if consumed in even small quantities; one teaspoon can kill a seven-pound cat.

Here's my take:Cockroaches - we don't see them often in the north, but if I did, Boric acid takes care of it.

You have to shock it with acid, let the stuff collect on the bottom, and vacuum it.

I will either end up watching others play and have fun the warm waters while I wonder what could have been or watch them burn in the acid bath while I bandage my big toe. 

Be careful what you use on the floor, if it has had muriatic acid used on it it may not take the stain.

Pulled the stumps with my super duty, sodded, muriatic acid on the pool surface, essentially aguttinh but notreally.

Once the cat urine gets in the wood, it's in for good.There are typically two ways to work on a stain like this, wood bleach and oxalic acid.

Or they added that section later.Concrete is fairly inert once dry, so I would suspect thin wall copper combined with acidic water supply = pinholes.

An application of Sodium Percarbonate PerOxyhydrate will help neutralize the uric acid and the heat will open up the pores of the concrete with the extraction pulling the materials out.

Several other shocking pictures were found down there including the whole crawl space was covered in white dust which looked like Boric Acid.
