The Bottom Line: Nature's Source Natural Bathroom Cleaner is an outstanding toilet bowl cleaner with a fantastic smell. With a very thick formula, it really sticks to the side of your toilet bowl and really cover a wide area and cleans your toilet bowl as effectively as harsher chemical cleaners. A definite winner in my book! Performance Method is a company that makes non toxic cleaning products, and I have tried many of them, and have had good luck with some, and disliked others, but I have to say that this toilet bowl cleaner has really impressed me in its ability to really get rid of the unpleasant rings that always form around the rim. Not only does it clean very well, but it is also much better for environment. This cleaner gets it right all around and I recommend it to all of my friends. I love the shape and design of the bottle, it is almost too cute to put away. I love how easy it is to twist the the clear cap up so that you can squirt out the product into the bowl. You never have to worry about losing the cap. Scent Method Lil' Blue Bowl has a great, natural Eucalyptus mint scent and what a lovely change from the usual chemical smells from other regular toilet bowl cleaners! It smells natural and earthy, and much less offensive than chemical cleaners.
