Hoover then damp emop with method wood floor cleaner. I have laminate, acres of bloody laminate including the kitchen which is permanently filthy but I can get it clean doing this...... Until the next meal!
I have 90 year old parquet, which has been sealed. Mostly it just gets vacuumed, but from time to time I wash it with an e-cloth and a light bleach solution (Cillit Bang) on my hands and knees. The edges particular near the skirting get very black.
Method makes a wood floor cleaner which smells of almonds and smells gorgeous. I spray it on and then go over the floor with a microfibre broom thing. Don't mop - it will leave too much water behind and could make the boards warp.
