DIY Car Wash Soap

For $5 I can get a "touch-free" automatic car wash that includes a spot-free rinse. I clean my car, on average, once every week. Doing the wash and rinse cycles myself will save me around $20 per month.


Shirley and I are now both retired and a fixed income is in our present and future. We shall be creative in finding ways to cut back on spending.


I Googled "Homemade Car Wash Soap" and found an informative article. I believe I will get some Murphy's Oil Soap and try it. Only 1 fl. oz. of that product is required in my bucket of warm water.


How about you folks. Do you have a car cleaning product of your own invention? And do you have some hints for living more economically? Any ideas will be most appreciated.
