Bench. Depending on what your bench looks like and if the lines, color and style fit into your home, you may be able to get away with using it inside during the cooler months. If you don't have enough space in your entryway, consider using it at the kitchen table or near a window.Tip: Use a soft-bristled brush to remove loose dirt and then gently scrub with soapy water. If there is mold or mildew, you may want to use white vinegar diluted with water to remove it. If this doesn't work, resort to a bleach and water mix. Spray down with a hose, pat dry with a towel and wait until it dries completely before bringing it inside.
