Dealing with cat pee is no miracle

So we had a couple of families over for dinner on Friday, and then sure enough Sophie peed on our bed sometime after everyone left. This time the pee soaked through the mattress lining, so we sprayed it with this solution called "Nature's Miracle". Next morning it still stunk. I gave it another drenching, waited an hour, and it was still bad. So I hit the net and got some advice.

Cat pee is mostly ammonia, so a 50/50 solution of white vinegar took care of that, and then I applied a paste of baking soda and water to neutralize the vinegar. As soon as I vacuum up the residue we'll have a clean bed again for the neurotic cat (and us) to sleep in.

But I had a look at that "Nature's Miracle" label. For eight bucks, you get water, "Nature's Enzymes", isopropyl alcohol, and "citrus scent". Something smells here, and it's not lemon fresh. From what I recall from my bio-science courses, all enzymes are nature's, and isopropanol probably does a good job of denaturing them. But it is a good disinfectant.

So here's my plan. I'm going to pick up some isopropanol for a fraction of the price at the drug store, and mix it with 2 parts water in the spray bottle. Next time Sophie pees on the bed, I'll try the cheap miracle to disinfectant the area, followed by the vinegar and baking soda, and report back here.

Yay, good work on cleaning up cat pee :)
I am proud of you!

And yes, green chemistry is a myth (and usually a big time rip-off). But it keeps me employed so I better shut up :D
