When I was young and carefree, I cleaned in a very basic manner and did the bare minimum. Cleaning things thoroughly takes a lot of time and effort that some of us simply do not have. Basic and bare minimum cleaning involves wiping off surfaces without removing the items on top of that surface to clean under those as well. Typically, a quick clean does not involve dusting everything and cleaning the baseboards. What about those pesky fans and vents that collect dust? You either don't want to be exposed to that dust or cannot reach the fan or vent anyways. Then there is the toilet. I saw a post on social media one time that had an example of a cleaned toilet and it said that true cleaning means cleaning more than just the toilet bowl and the seat. Cleaning all over the outer surface, including the bottom and floor around it, is how you truly deep clean a toilet. Most people do not want to touch that though! This is an example of something that would be great to hire a cleaning company to deal with! Another example is sweeping, but only spot sweeping. If you do not go over the area a few times, you are likely missing a fair amount of dirt or crumbs. A great technique is to start from one side of the floor, get the corners first, and sweep in sections to ensure you get every part of the floor. The Swiffer mop was a neat invention, but it seems to just move the dirt around and it does not help to remove tougher spots like a spill in the kitchen. I prefer to do it old school where I get on my hands and knees with a scrubbing tool to remove the tough spots first, then go back over the surface with a mop, let it dry, and finally add some degreaser to create some shine and get rid of the stickiness the floor can sometimes get. Basic cleaning of a sink involves wiping it out, but deeply cleaning a sink involves cleaning the faucets, drains, and the area around the sink. It is also helpful to wipe out the sink with a paper towel after each use to remove the water that sits in the sink and creates a film that can attract bugs or cause a foul odor.
