To naturally clean and shine your hardwood floors you can mix a cup or two of white vinegar into a bucket of warm water.
Then take a mop and mop the hardwood floors with the vinegar and water.
The vinegar is a natural hardwood floor cleaner that will help clean and shine the wood floors without harsh chemicals.
Just be sure to dry the hardwood floors properly to prevent them from cracking and warping.
To help the hardwood floors shine even more you can polish the hardwood floors by using olive oil which is a natural hardwood floor shiner as well as being useful for just about anything else.
I shine my floors with olive oil naturally after mopping the hardwood floors with vinegar.
