Regular cleaning is what is done on a weekly, bi-weekly basis to include cleaning the kitchen, cleaning the bathrooms, vacuuming and dusting. Deep cleaning is very different and is often a requirement before a move in or out. Deep cleaning does not have to be only for move in or out, you may want to hire for this service while you live in your home. Deep cleaning is different from regular or spring cleaning because it reaches the deep grime and dirt in your home. It covers areas which are not covered by a regular or spring cleaning. These areas could include under the sink, inside the kitchen cabinets if empty, inside the fridge, inside the stove.
The key difference between pressure / power washing vs soft washing is what is actually cleaning the surface. The soft washing method, environmentally safe chemicals are cleaning the surface, and with the other methods it is the water pressure that cleans the surface.
