If you make a concentrate of any natural cleaner, you will save money. I make a concentrate for all purpose and glass cleaner. It costs me $0.09 cents for a 32 ounce bottle of all purpose and $0.04 cents for a 32 ounce bottle of glass cleaner. Eight ounces of concentrate for both will last me 30 days. Mix with distilled water to get to the 32 oz.
My non abrasive scrub costs me $0.02 for 8 ounces, abrasive scrub is $0.05 for 8 ounces. Eight ounces of these scrubs last me 14 to 16 days.
The recipes for the cleaners are tried and true. I have been using them of over a year and, as you can see, the cost is almost nothing.
I do not use anything purchased off the shelf or ready mixed.
