These "John Bombs" are an amazing tool to keep in your cleaning arsenal! Why fuss with a bottle and dealing with messy liquids? Just drop one of these "John Bombs" into your commode and watch it fizz and fill the room with a scent that actually smells amazing, instead of harsh and harmful chemicals! I've been using these while cleaning my bathroom due to my respitory issues (asthma.) I can't use regular cleaners because of the toxic airborne smelling chemicals and Vinegar can only clean so much. Did some research and started making these wonderful little bombs for when I'm cleaning or drop one in as a toilet bowl air and room freshener when unexpected guests show up. Buy them in our "ready for the john" white container (container comes with 12 John bombs) or purchase any of our refill bags (bags contain 12 or 24 John Bombs)  and fill your own container.
