Dusting and sweeping
Use the StarMop dry—do not wet! Glide the mop over surface to pick up dust, dirt, pet hairs, etc. However, remember that the StarMop is a floor duster--not a vacuum. When pad becomes very dirty, just shake off the Mop Pad to remove loose dust and particles. You do not need to wash the Mop Pad after every dusting--just wash the pad when it becomes soiled or very dirty.

Cleaning and polishing
Use the StarMop wet to remove ground-in dirt, dried-in stains, mud, sticky messes, wet spills, scuff marks, etc. (tip: for tough scuff marks, while mopping, press your foot on top of the base, and push down for pressure). Lightly dampen the Mop Pad with water by rinsing under the faucet and wringing out, or mist with spray bottle. Do not over wet the mop pad. If pad gets heavily soiled while cleaning, simply remove pad from the base, and rinse out under the faucet. The StarMop can be used effectively with just water, however preferred non-toxic or chemical cleansers can be used.
