I believe that the surface is dull and looks filmy because of damage to the top layer(s) of the manufactured finish...

I have come to the conclusion that any effect of the cleaners I use will be only to clean present dirt on the surface, but will do nothing to repair the damaged finish..

I know that there are all sorts of ideas discouraging the use of a wax or similar product that will give a shiny surface...but ours is damaged to much to have any hope of improvement to a shiny look, without the use of some material that will give a buildup over time.....

There is a product that I will try next...Pledge Future finish....it has good reviews, and can be removed rather easily, say on an annual basis......I will try Future in an out of way place first..anyone have a comment on Future?

Wow!...we cleaned the floor using some of Bona, and some of Zep cleaner...then after that dried, we applied a coat of Pledge Future finish.....it gives a clean, glistening look to our hardwood floor that brings out the beautiful grain of the wood......

This is an absolute winner for us....we think, based on other peoples experience, that the floor be cleaned and refinished on a yearly basis......it could not be worse than what we have put up with...

We used mop and glow on 3 rooms of old Parquet wood floors. In a few years it built up, blackened or got milky. We stripped it with Zep stripper . (No other product we tried would get the mop and glow off.) Sanding was not an option. Professionals not an option.

I'm 70 and my husband is 80. We used a scrapper to get the mop and glow crap off with the Zep stripper in sections as our backs allowed.

There was very little if any odor. Did a wonderful job. Just blocked off the area we were working to keep the 2 dogs and 2 cats away.

After watching Cheap Geek on youtube - https://www.youtube.com/watch?v=ePOlRPa0N7E

We put 3 coats of Zep wet look ( not recommended for wood floors.) Really don't know why. We Love it. It's been on for a 1 1/2 years.

I can spot clean with more Zep in high traffic areas. You just have to have real clean floors with no pet hair in that area. Drys super fast. No bad smells. Works good on your vinyl dash boards in cars too.

Great stuff ! Annette
