Cleaning bamboo floors

Try Murphy Oil Soap - it's for wood. It comes premixed in a spray bottle or in a concentrate that you can mix. It leaves a soft shine, not oily.

Did the poly coating get damaged? I use Bona cleaner on my clients floor after vacuuming it up cause they have a lot of pine needs, and once in awhile I use vinegar and water although I don't like to do this regularly as it can take the shine off the finish.

White Vinegar diluted w/water.

So sorry to hear - what products have you used before? Can you go to the manufacturer - or a good flooring specialist and ask them what to use? Maybe taking a picture or two would help.
