The optimal time of year to undertake a thorough deep cleaning of a house is widely considered to be during the spring months, specifically in March or April, giving rise to the traditional practice known as spring cleaning. Cleaning a home during this transitional period allows residents to open windows to air out stale indoor spaces accumulated during winter, tackle accumulated dust and grime, wash windows, and reset living environments for the warmer months ahead. Alternatively, early autumn (September or October) serves as another ideal window to deep clean before sealing up the house for winter.
