First off, I do not dust/clean weekly. Don't get a negative picture....it's only my husband and me......we
entertain about every 3-4 weeks so that is when I clean....I mean really clean....the week of company.
By that time I can see a considerable difference after cleaning and gives me instant gratification...cleaning in this timeframe also gives me more time during the month. We "pick up" on a weekly basis so cleaning is pretty much a snap. I've been doing my cleaning this way for 30+ years and find it works for me! (Dishes in the dishwasher are done "as needed"...not everyday.)
