Fels Naptha Soap
There, that's no so hard is it? Chances are you have a few of the items around the house right now. you can replace Windex, tile cleaner and counter top spray by mixing Vinegar 50-50 with water in a spray bottle. Use it as you would and counter top cleaner or window cleaner. It leaves mirrors sparkling especially when you use newspaper to wipe with instead of paper towels. Tile can be cleaned with a paste made of baking soda and some water. For general cleaning dissolve a couple tablespoons borax in 2 quarts hot water and wipe down the surfaces to be cleaned. To sanitize and deodorize sink disposals pour in 1/2 cup borax and let sit an hour. Turn on the disposal and rinse with hot water. Add some borax and washing soda to laundry to make your detergent more effective or better yet make your own laundry detergent for just pennies per load (more on that in another article). A mixture of salt and vinegar into a paste will shine most metals. To clean drains of soap scum pour in some washing soda and little hot water. Let sit for 15 mins then flush well with hot water. Have a steam mop? mix in some vinegar with the water at the ratio of 25:75 (vinegar:water) to get your floors sparkling clean. Don't mind the vinegar smell as you're mopping, it quickly dissipates and deodorizes the air.
I've given you just a few of the ways I use these "Vintage" products around my home. The total savings is around $200/yr in cleaning products, much more if you make your own laundry detergent.
