The veggie burger she buys runs $8.95/lb plus delivery & when BBQ'd it has the distinct odor of fermented silage (a.k.a. cattle fodder).

I'm told it will kill everything in the home, plants,animals and of course foul odors.

Still a strong odor in 2 bedrooms.

And in any rooms that have wall stains and odor from kitchen grease or cigarette smoke, do you like to also specify in writing any extra steps you expect them to take BEFORE painting those areas?

If dirt and odor and stains are not present, you may be able to skip the TSP and/or the Kilz steps.Replace or paint the acoustic tile if it is stained and/or has a bad odor.

My partner and I decided we could pay a specialty cleaning company to clean out the mess and odors, then turn around and resell it on the market to other investors as a gut rehab or tear down.

Lowe's has some stuff, can't remember the name, that does a great job without the odor of bleach.

However, it can certainly move odor.
