I have been using clean & simple for years and I love it! I have a diluted bottle in almost every room in my house. It works great on all of our stains...three kids and a dog, I have even used it to clean our fish tank! Carpet stains are no problem my kids could paint on the carpet....no worries! What I have found to work best is use really HOT water and apply generously...no really spray the stuff it's economical. Then all you should need to do is blot out with a cloth, and repeat if necessary, but if you do it good enough the first time you shouldn't have to. Also when you shampoo the carpet use really hot water and pre-spot noticeable stains first and it will work great! I also love it on our RV, my patio furniture, grease on the stove, countertops, walls, kids, kids tennis shoes, laundry stains anything and everything I love it! Thank you Sierra Solutions for helping keep our house amazingly clean!Oh and my last order has lasted my home 4 1/2 years....so yeah buy clean & simple and save your money....it lasts a LONG time! Thanks again!
