Deep cleaning is the most thorough type of cleaning available. It’s similar to getting your teeth cleaned by a dental hygienist, as it addresses the bacteria that collect below the gum line and around the root surfaces of the tooth. It’s necessary to prevent gum disease and is typically performed once or twice a year in addition to regular brushing, flossing, and using mouthwash.

During a deep clean, every surface is addressed and every nook and cranny in the room gets cleaned. A cleaning service should follow a deep cleaning checklist to make sure nothing is missed. This helps ensure the home is properly cleaned and sanitized, as well as sets a high standard for regular maintenance cleaning.

Deep Cleaning: A Complete Guide to Sparkling Clean Spaces

The most common areas of the house that require a deep clean are the kitchen and bathroom. These spaces often harbor bacteria, food splatters and mold, which can cause sickness in family members and guests. Bathroom shower heads should be deep cleaned at least once a year to remove minerals that build up and restore proper function. The refrigerator should be deep cleaned monthly to remove the growth of bacteria caused by old food splatters, while the oven should be deep cleaned weekly to eliminate germs from rotting food.

Other areas that should be deep cleaned are the bedroom, living room and basement. Pillows and mattresses are a hiding place for dead skin cells, sweat and oil, dust mites and pet hair, and can harbor odours. Bedrooms and living rooms should be deep cleaned quarterly, while basements are usually a breeding ground for rats, spiders and cockroaches.
