Ok Lounge - a real challenge for you pet owners -

1.I wash our dogs in our tub, which is very old and has lost its porcelain glaze.

2. This spring was very muddy, and the sandy clay soil we washed off the dogs left a red brown stain on the porcelain.

3. Recently, we noticed a strong ammonia smell every time the tub gets wet.

4. The only thing we can figure out is that there is some old urine trapped with the clay stain.

So, am I correct about the source of the smell, and if so, how do I get rid of it?

1. bleach reacts with ammonia to make Chlorine gas - so....

is you decide to use bleach - pour it and run!!!!

2. The daughter who is home on vacation has a degree in Environmental Engineering,

so she knows all about not mixing chlorine bleach and ammonia.

We're trying soaking overnight with an enzyme cleaner.

4. was just being silly but it sounds like you have an expert available, I will hve to ask you for help

When I worked at the animal shelter that is what they did for the urine smell in the dog buildings outside. so when My dog peed in the basement, I opened a window, held my breath and poured some bleach on it, then ran upstairs and shut the dorr for a few days, Itdid get rid of the smell.

3. I think tubs can be reglazed.

That is the entire sum of what I know about this. Also, I would worry that the glaze would react with the urine.

p.s. Please let us know what works. I never have managed to fix the bottom of a bathtub that the previous owners had decals on.

5. My mother had a tub reglazed years ago, and it held up fairly well.

Of course, she was vary careful to avoid any kind of abrasive cleaner.

I think this tub is a goner - it was old when we moved in 30 years ago. I'm hoping for a remodel job in a few years, and plan on a concrete floored spot to wash the dogs.

7. vinegar, hydrogen peroxide,

Vinegar

A sour-tasting liquid, vinegar contains acetic acid and removes a wide array of odors from a variety of surfaces. Vinegar will neutralize ammonia while getting rid of the smell. Since vinegar is inexpensive, many people use the versatile liquid to clean their homes from top to bottom. To remove the ammonia odor, blot or spray the area with pure, undiluted white vinegar. Let the vinegar dry on the surface. Reapply the vinegar as needed until the ammonia odor is no longer present.

(ammonia is basic. vinegar is acid. mixing acids and basics neutralizes both. I would try buying the biggest containers of the cheapest vinegar I can find, pour it in and swish it around so all surfaces are wetted. Then let it air dry. Rinse with water. Repeat until it smells like vinegar whether it's wet or dry.)

Hydrogren peroxide will also work, but is more expensive.

9. Try a paste of baking soda and hydrogen peroxide.

Let it sit a few hours or over night if possible and then scrub.
