2/10/2017 Update:Lowered price on Amazon again, and even better deal with subscription! Just make sure you wear gloves. This stuff works, but it will dry your hands out for sure.UPDATE.2:Lowering my rating back down to three stars only because they've done it again with their pricing. This single bottle is right at $15 when you can get the two pack for $20 on Amazon. However, even that deal has the company back to selling this water-diluted version at the same price as the original full strength. Not good.UPDATE:Not sure when they did it, but Charlie's Soap has lowered the price of their diluted K&B product, so I'm changing my rating to 5 stars! Way to go! Will be buying more today.ORIGINAL REVIEW:Noticed kitchen and bath ingredients were same as our bottle of Charlie's Indoor/Outdoor. Called the company, and rep was very polite and honest - explaining that it is the same product simply diluted with more water.So why charge the same? I know companies play this label game all the time with their products, but this definitely doesn't sync with Charlie's corporate personality/philosophy.It works great on bathtub scum and cleaning in general. Much easier and safer than all those harsh chemicals that 'clean' your sinks and tub.Charley's Soap is a must-have in my house. It basically gets out anything. Every morning I spray my sink in it because gunk from my garbage disposal backs up into the sink at night while the dishwasher is running, leaving a dried mess in the sink. I just spray Charlie's Soap all over the sink, make my coffee, then wipe off. It's almost effortless. The key to Charley's Soap is that it needs a couple of minutes to do its magic. This is not spray-n-wipe windex, but it's also not filled with icky chemicals either. Charlie's Soap also gets out EVERYTHING from chocolate stains to blood to pet messes. When my bottle is about half full I start to get nervous that I will run out, and I rush to order more.I can't tell you how much I love Charlie's Soap. The Kitchen and Bath spray cleans gently and without filling my lungs with chemicals. The trick is to let it sit for a few moments before you wipe it up. My brother got a large jug of the Indoor/Outdoor concentrate (which I understand may have an additional enzyme in it), which I will dilute to refill the spray bottle when it's empty. And if you haven't tried the laundry soap, you're paying too much for crap. I've used nothing but Charlie's liquid in my front loader and never got the front-loader smell that people complain about (it's from detergent residue); I never use fabric softener and my clothes/sheets/towel are always soft. Charlie's Soap rocks!I have been a fan of Charlie's laundry soap for a while but wanted to try this too...After my sister used it on her shower she called me excitedly to tell me how well this worked on her shower. So, I bought some, sprayed it on my shower walls (which were filthy, they hadn't been cleaned in a while and had a lot of hard water and soap stains), waited 15 minutes or so, went in and lightly wiped the shower walls...The dirt melted away under my sponge! It rinsed out clean and my shower walls looked great! I am a forever user of this for my shower for sure! I also use it on couners, sinks, etc., anything that needs to be cleaned, really!I bought this cleaner because of the success I've had using Charlie's Soap laundry soap for my family's laundry and the fact that I prefer non-toxic cleaners. I'd hoped for a moderately good cleaner, and my hopes were blown out of the water. It is amazing. Makes my bathroom and shower sparkle. Works well on my stovetop and other kitchen surfaces. It has replaced the huge variety of cleaners in my home, and works better than the nasty, fumey, toxic ones. The kicker was yesterday when my son had a bloody nose and bled a large amount on our brand new carpet. First I tried Folex, which lightened the spot, but it was still visible. So I tried Charlie's and the stain was immediately gone with no elbow grease. Customer for life!I ordered this and also have the Charlie's soap Laundry. When this bottle was empty I put 1 1/2 pump which is like 1 and a half ounce in this bottle after I filled the bottle with water almost to the top leave some room to pour in the laundry soap. Tighten pump shake and you can use the laundry liquid for general cleaning I think it works even better than the kitchen and bath. I have a cleaning business and I use it to clean everything from sinks, wood, to tile floors.I love this cleaner! Keeps my kitchen nice and clean without harsh chemicals.
