"In a private comparison application of this product versus a nationally know brand name, the Bioklean product was not even close to being as effective. Returning it and going back to the inexpensive vinegar and dish detergent formula that is readily available on the internet. I'll reuse the empty bottle from the nationally known brand to fill it up with the home made formula."

"I can't find a quality eco friendly glass cleaner to save my life! The only reason I bought this one is because I have the concentrated Biokleen all purpose cleaner and I LOVE it so I figured I'd get matching products. This glass cleaner smells purely of vinegar and when sprayed on windows looks like nothing but water and leaves tons of streaks. I have to go over everything with a dry microfiber towel just to get rid of them."

"This is my favorite glass cleaner. You can definitely smell the vinegar and my cleaning lady always raves about the fact that it doesn't leave streaks on the glass. One thing to note is that if you buy this from Amazon, they package liquid items horribly. Other companies I've ordered from will at least tape the top of the bottle so it doesn't unscrew during delivery except for Amazon, which is hard to believe considering they are the number one e-tailer. I've had multiple bottles of this cleaner spray spill open and ruin all the contents of whatever box I get. This is the last time I'm ordering this particular item from Amazon."
