Just had a very pale Kahrs engineered wood floor installed in the kitchen. It looks lovely but is surrounded by big windows and you can see footprints/scuffs across it as it hasn't been cleaned since it was installed a few days ago. The installer warned against letting much water get on it so i'm paranoid about mopping. Any tips? I do think it needs a bit of a clean beyond sweeping which i've already done, just to get the muck from installation off. Thanks.
