Bona Wood Floor Cleaner Refill 2.5L 5 "Best cleaner for wooden floors" Mrs Coey 21 September 2020 I bought the bona floor mop and cleaner five years ago when we had our new wooden floor installed and was so delighted with the results I’ve never used anything else since. In the past I had struggled to find something good that didn’t streak without a lot of effort. This is effortless to use and gives a great finish to the wood. I buy this refill size and save a bit of money and plastic. I also bought my daughter the bona mop with laminate cleaner for her amtico floors. She loves it.
