We have real wood floors (not laminate) with a polyurethane finish. My installer suggests that we clean the floors with a mixture of about 1/4 windex and water with a barely damp mop. So that works well on the floors themselves.

But- our floors have a v-shaved groove in between the planks. We have dogs, cats, and kids, and between them and the garden, we have collected quite a bit of dust/dirt build up in the grooves. I'm sure we have not vacuumed as well as we should have- I know that will stop it in the future- but the vacuum doesn't get all that build up out.

Any ideas?
