Remove air conditioner return air filters located inside the ceiling vent covers.  Wash the filters with a mild soap solution and clear water rinse.  Wipe inside air conditioner vents to remove dust and debris.  When filters are dry, reinstall and replace the vent cover.  Turn on the air conditioner system to confirm it is in working order.

Build up in the microwave can be removed by filling a microwave safe mug with water and cooking it on high for three minutes.  Let the cup sit for another two minutes to allow steam to soften grime before wiping the oven walls with a damp cloth.  To eliminate odor, add a few lemon slices to the water before cooking.

Remember to clean the service tools.  Empty the vacuum bag, clean the filters, and if necessary, change the vacuum cleaner belt.  Wash the broom and mop.
