Biocide Systems 3220 Room Shocker Odor Eliminator

This product worked well for me. I had a spare room where my elderly cat lived, and she sometimes peed on the walls along the perimeter, plus she had a sensitive stomach and frequently threw up on her bed in the room, on the carpet, everywhere. The room had taken on this strong pet smell, not just the urine, but the barf and just stinky animal smell. I pulled up the rug, which was on top of concrete, I cleaned very well with "Kids n Pets" enzyme cleaner, and used Killz low VOC aerosol primer to seal the concrete under the damaged carpet, replaced the pad and carpet, and used the primer on the baseboards and lower 5th of the drywall. Let's say the urine smell was remedied with these steps. But there was still a musty animal odor in the room, not too terrible, but you could immediately tell a sick old animal lived here, and I wanted to use the room as an office where clients would come (I'm an accountant.) I waited until sunset, closed the blinds and sealed the incoming and return register for the central air with cut up garbage bags and masking tape. (The instructions say to turn off central air, but I live in Florida and it's hot, no chance we're doing that.) I used warm tap water, shook up the bag as instructed, and put the container in the middle of the room on a stack of books (that were also stinky.) Within an hour or so the room smelled like a pool, and the smell was seeping under the door, so I wedged a towel under it to seal the room. This worked and I could no longer smell the chlorine in the hallway. I left the shocker to work overnight. In the morning I opened the blinds and the window with a fan running in the room while I kept the door shut to let it air out. After a few hours I opened the registers and the door, and closed the window and let the a/c run, even though it still smelled strongly of chlorine, I could tell the gases had cleared, and it was just a residual odor. By the next day the pool smell was completely gone and opening the door to the room was no longer like being hit with a brick wall of animal smell- in fact, it smelt like NOTHING. No leftover pool smell, no musty odor, no cat barf or pee, really no discernible smell whatsoever. I'm back on amazon to buy some more of these, one for my car which has a yeasty sour smell (i'm guessing spilled beer from the 4th and years of milk spillage from my toddler) and my guest room which is infrequently used and has a stale smell. I think the source of the odor needs to be removed as much as possible- like, I'll need to shampoo the car interior first to clean the milk spills- but for those lingering stinks that work their way into soft or porous surfaces, this is probably an effective solution. I'm very pleased and would recommend this product to friends.

You have to be careful and place the container on a plate in case it splatters, due to the chlorine, and follow the instructions for sealing up the room. I had a room that smelled of cat pee and now you can't tell a cat has ever been in there!

We have a chest of drawers that is very clean, but with strong residual mothball odor. The chest and drawers had been thoroughly wiped down with vinegar, baking soda and aired. I spoke with two customer service reps at Biocide Systems to plan the best approach to using Room Shocker. They assured me that the product would eliminate the mothball odor with one treatment. I treated the chest inside a walk-in closet that was dark and well-sealed. Unfortunately there was no improvement. The waste of time and energy (days spent researching and planning this) was worse than the waste of money. After reading other negative reviews, I've decided not to bother with a second treatment. I'm not sure what the disconnect is between the company's claim and the poor results. I am very disappointed.

We had a chest freezer get turned off a couple frozen turkeys spent a month in it before we figured out what was making that godawful smell. I scrubbed out the freezer with Palmolive four times, with a bleach solution three times, with Fantastick three times, and then with Comet twice. The smell persisted.I got this and followed the directions perfectly and waited 24 hours. When I opened the lid on the freezer the inside was full of this crazy yellow mist and smoke. I have never seen that before. I removed the little cup, sprayed out the inside of the freezer with water... and the smell was still there. It was much fainter, but still there. We left the freezer propped open outside for a few weeks and after three or four weeks the smell did finally go away. But the 24 fix I was promised---that didn't happen. So just OK.

We moved into a 114 year old house with a lovely all wood office - floors, walls, ceiling and bookshelves. However, the office gave off a weird, musty, dirty odor. I started by washing down the floors and even the walls and then moved to the bookshelves. When I hit the bookshelves the strangest thing happened - cleaning them made them super smelly. So I followed up with baking soda on the shelves which did remove the odor after 24 hours.But still the room had a funky smell. Enter the Room Shocker, which I read about on Apartment Therapy. I followed the directions - warm water - and I started the room shocker right after the sun had set to get maximum darkness while it worked. The next morning, slight chlorine odor but after about an hour of airing out (this room doesn't have the best ventilation) the odor is gone 100%. Amazing and so pleased.I don't understand the reviews that aren't as good (I would say clean the room thoroughly first and use at night) because this is 100 times better than the Bad Air Sponge - which I tried too. That only helped a little and had a not very pleasant odor of its own. Room Shocker is no-odor. This will be my go to for bad smells in the future.
