x100! Super thank you to all who recommended this!
Got the machine yesterday, paid $129/Free Shipping. Covers 3,500 sq feet, commercial model. Brand new.
Did 1 hr on, 1 hr left alone with closed windows - odor 90% gone, so much better.

Did another hour today, same time, and it's gone baby! Has a faint bleachy smell for just a little while, and then a neutral type odor. I decide tomorrow if it needs any more treatment. Did the VX for an hour today, still sitting in garage closed up. It was kind of starting to smell like "old car" smell, thought it could use a blast of this stuff. Next I'm going to try a few rooms inside - like kitty box area.

I got a face-full of it the first time I turned it on, had it on floor mat and leaned over to turn timer dial - WHAM! that stuff instantly starts blowing air that smells farily strongly of this bleachy type smell.
Note to self, next time - hold breath, turn dial, turn away ASAP and slam door and run.
