Do these products work? I see there is a recipe in the latest sullivan catalog from a guy encouraging 2/3 double dip and 1/3 rag oil for use mainly in the winter months. I have also heard of a little rag oil mixed with kleen sheen. I currently use a lot of kleen sheen mixed with vinegar. Is there a benefit to the rag oil and double dip over my current mix? If they work I'm interested, but don't want to spend extra money if there isn't much benefit over what I'm currently doing. Thanks.
