KRUD KUTTER, I applaud your efforts at 'green' cleaning, however you disappoint this consumer when it comes to one specific area - mildew removal."Cleans what ordinary cleaners simply can't!" doesn't seem to cover mildew as stated on your label.  To me, that's a basic and one that's a pretty good test for any cleaner, particularly biodegradable ones that are not designed to bleach, but rather to eat away stains.What KRUD KUTTER can do is offer a color fast, fabric safe, 'earth friendly' cleaning solution to help you clean up things that are sticky, greasy, oily or waxy. It is good at basic clean-ups, but what it can't do is everything it claims on the bottle.Perhaps my expectations were just too high, and perhaps it was my experience with another product, but this one is just OK to me, thus the 3 out of 5 stars.What I like about KRUD KUTTER:+ Earth-friendly; always a good thing.+ Concentrated; all jobs don't need full-strength use, thus the product lasts longer in theory.+ 'Safely' removes... although this one is questionable as there are warnings about eye and skin contact, as well as ingestion.+ It does work on things like shoe scuffs on vinyl and wood flooring, without bleaching the surface.+ It cuts common dirt and grease very well at full strength, including hairspray residue.+ Biodegradable, thus safe for use on RV's, boats, and plumbing that feeds to a septic tank.What I don't like about KRUD KUTTER:- The very first thing I tried to clean was mildew spots on my bathroom ceiling (a teenager who likes long showers and doesn't turn on the fan...), and at full-strength with 3 applications - it did not go away. I began to see them lighten, but they did not go away completely via just spraying and leaving the cleaner to do its work.  Eventually I wiped things down and it looks OK, but the bottom line on mildew - a bleach solution still works better, as doesSimple Green 11001 Clean Building All-Purpose Concentrate Cleaner, 1 Gallon Bottle.  Might just want to scratch 'mildew' off the list for this product, or not put so much hype on the bottle.- If it works, most jobs require full strength application, despite what it says on the label regarding dilutions.For sticky, greasy jobs this cleaner works well.  But I'm not completely sold that its claims match what it can do on all fronts.  A good, Earth-friendly cleaning product, but not an 'all-purpose' one.If you want to try another product for greasy and sticky jobs, that I like better, I would recommend tryingSpray Nine 22732 Grez-Off Heavy Duty Degreaser, 32 oz.instead, which is also biodegradable and works incredibly well!  Spray Nine's product is least 80% more effective on sticky and greasy messes than KRUD KUTTER, and it costs less too.Although it too, is not for mildew.UPDATE: 7/8/13I've boosted my rating from 3 to 4 stars for this product.  The more I use it, the better I like it, particularly for sticky residue on vinyl flooring.  A wet mop with a quick spray of this lightly over the surface, seems to do a better job on my kitchen and bathroom floor than any other cleaners I've found.  It's not as heavy-duty as Spray Nine, but the fumes are much less too and if used frequently there's no need to use a stronger product.
