These are nice check lists, but for normal house cleaning services, we dont get paid enough to go through ALl the steps mentioned. Top to bottom is important when cleaning anything.
In bathrooms, I use a wand vacuum with a very bright headlight, after I have removed all items that can be (NOT the cosmetics and stuff people leave on their vanities!) I vacuum, and using the light, can see if walls need dusting, light fixtures, whatever. My vacuum has attachments, such as a very long nozzle head, so if I see there is a lot of dust or hair or whatever in a hard to reach places, the attachment gets it for me. Walls are easily dusted with a dry floor cloth, like a Swiffer.
A comment on floor cleaning, and its a big one. If you are using an old fashioned mop with a bucket of water, all you are doing is swishing dirty water around on the floor! UGH! I use a Swiffer mop but NOT their wet pads (they leave the floor sticky and they dont smell good.) I attach white washcloths to it, and they fit perfectly. Ordinary, cheap washcloths! I mop a fairly small area - perhaps 4 X 4 - and when the cloth stays white, the floor is clean. My customers seem to LOVE it that I pay attention to details like this.
I will share a story with you all, a true one. I began cleaning a new customers beautiful waterside condo several weeks ago. She has beige tile throughout the condo. As I was mopping it for the first time, I saw that it LOOKED like the tile had darker "veins" running through it. In other words, that that was how it was supposed to look. The second time I cleaned that floor, I had enough time to investigate this further. Guess what? Those dark "veins" were NOT supposed to be there...they were built up dirt! Using a Magic Eraser, I easily got it up. I brought this to the attention of the owner. She told me that before she hired me, she used the same house cleaner for quite a few years, and that SHE mopped using a bucket and cloth type mop. Perfect example:: mopping that way - you are just moving dirt to a new place. It has taken me 4 visits to her house to get even a quarter of that old dirt up. Luckily, this lady has money, and she appreciates my hard work. I will never forget this important lesson.
