I've heard you can make your own hardwood floor cleaner. I hope it's true because I just made some and tried it.
I found that you can mix 1/2 C white vinegar with a gallon of water. I broke that down to 1 T white vinegar with 2 C water. I read
somewhere else that you can mix 1/4 C vinegar to 30 oz water. That breaks down to approximately 2 T vinegar with 2 C water. I thought I'd try the lesser amount of vinegar, though, this time. It seemed to work very well. I just sprayed the cleaner on the floor and wiped it off with an old terry-cloth towel.
I also read somewhere that you can make your own hardwood floor polish from 1/2 C vegetable oil with 1/2 C white vinegar. I want to research it just a little more, though, because I'm a little worried about putting that much vinegar on the floor!
*** Apparently you're not supposed to use vinegar or oil soaps on Bruce hardwood flooring, which this is because it ruins the finish. Oh well, guess I won't use it anymore. I've probably already ruined the finish, though, by using my Murphy oil soap. Guess it doesn't help having little kids either....
