The product suggested by the manufacturer. But first some basics:

1) Sweep/dust mop routinely (every 1-3 days...yes...could be once/day)

2) Microfibre damp mop (water only....lightly damp...almost dry) once/week

3) Hardwood CLEANING product (preferably by the manufacturer of the wood floor) applied to "damp mop" (see instructions above) every 2-4 weeks.

Vacuuming can be used in place of sweep/dust mop...but the beater bar must be turned OFF...those bristles can damage hardwood finishes faster than the grit/dirt you are vacuuming.

That's it. That's all there is. Sweep/dust mop almost daily. Lightly damp MICROFIBRE mop 1/week. A true "cleaning" product used every 2-4 weeks. Done. Nothing more.

Dark(ish) hardwood = more sweeping. Have fun.
