This is amazing stuff. If you have read about it online and wasn't sure about the results, I can swear by this mixture. I used about 1" of dawn dish detergent in a spray bottle and filled the rest with white vinegar. The recipe calls for the vinegar to be heated but I forgot and it works just fine. Let me tell you, I have an old bathroom and it worked wonders removing soap build-up on the glass doors. The chrome shines like never before. I sprayed the mix on the shower and let it sit. I left it for almost a half hour because I was busy doing other things. So I went to take my shower and just washed down the doors and walls with water and a rag to get the soap mixture off - no scrubbing. That was it - amazing. So I tried it on my sink - shine. I went to my kitchen sink and my glass top stove - it's a mirror now. I also tried it on a grease spot on a shirt but I haven't wash it yet, I will have to get back to you on that experiment. If I haven't said it already, you have to try this stuff! No kidding!
