I never recommend household cleaning products such as Murphy's,
Murphy's Oil Soap had a booth at the convention. I spent some time talking with them. Theya re claiming that their product is safe for wood floors and does not cause any recoat adhesion problems. They proudly display samples of recoats over their product and have some customer testomonials from some very prominent floor people, including Berger, who proclaims he has been using it for years.
This certainly goes against everything every finish manufacturer has ever advised and I was interested in this Murphy's marketing drive. Give them credit for facing the heat and I had a good time giving them some. They withstood it well and in good humor.
They were at a loss for words though when I asked them if they had done any tests of recoat longevity over their oil product. They have a fancy, circular explanation of the "oil" thing, bottom line is-it's still an oil-derived product. Anyway, as many can attest, a finish applied over a poor surface may stick and show no adverse reactions to such abuse while their erstwhile floor finisher cashes the check, but the finish will wear very quickly.
My wife once made the mistake of using some such product on our kitchen floor. Pine Sol, I believe...scented Pine Sol. After expressing my displeasure of her actions, I eventually recoated the floor with two coats of Street Shoe. All signs of that finish were gone within six months. She is now my ex-wife.
So, back to the subject, the nice folks at the Murphy's booth had never heard of this phenomenon. Stumped and wordless, I felt some sympathy for the nice people and asked them to just go back to their testing laboratories and please see for yourself. They agreed and promised to report their findings back in a timely fashiion.
Yeah, right.
