Clean high-traffic areas such as kitchen surfaces, bathroom surfaces, and bedding once per week. Deep clean other areas every three months to a year. How you use a space can help you figure out how often it should be cleaned, with areas where eating, bathing, and food prep occur getting the most frequent attention.

The simplest way to clean stained glass windows is by using warm distilled water and a damp cloth. Distilled water won’t corrode the stained glass or leave residue behind. Avoid using cleaners with alcohol or ammonia. However, you should only clean when necessary. Stained glass windows are fragile, and excessive cleaning could cause fading, weakening of the solder, or other damage.

Whether you’re a renter or a buyer, you should clean a house when moving out. For renters, it’s usually written in the lease that a house must be cleaned before it’s vacated. If you’re unsure how thoroughly to clean the place, check with the landlord beforehand; otherwise, you may not receive your deposit back. When selling a house, a contractual agreement is often made with the realtor that the house is swept and that all personal belongings are removed before the previous owners move out.

While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.
