My Mom used to own cleaning companies so it was one of my first jobs. I actually enjoy cleaning...my own home. It's awful cleaning other people's homes. You're not just cleaning the usual spots, but all those places that most of us hate to clean and thus they are usually filthy in other people's homes - think blinds, windows, baseboards, the really grimy parts of the stove, mold, mold and more mold. I was shocked at how dirty so many people are. They usually expect miracles in the short time frame that they paid for when it could take you all day just to clean their kitchen. And, yes, it can be weird and uncomfortable being in someone's home especially if they're in the home while you're cleaning.
If you decide to do it, here are some tips:
-Bring some of your favorite cleaning items that you KNOW work miracles. If you have non-toxic formulas, even better. I used to have this cleaning paste by Shaklee that worked miracles on tough, grimy sinks, stoves, etc. It would save me so much backache when all the person would provide was spray cleaner and expect me to get years worth of gunk off. Bring your own squeegee for glass shower doors.
-Treat their home not just like you're own, but like they're getting something special done (even if they're regulars), like they're in a hotel. Some people don't like it when you fold the toilet paper, but it's usually a nice touch. If you want you can bring little candies to put oh their pillows, or print out sweet/zen sayings on cards and put on their pillows. Little things that show you care to go the extra mile.
-Research good tips and tricks. For example, lemon oil swiped on a glass shower door after it's been cleaned will help the water bead off and not create as many water spots.
-Learn the proper order to do things (dust first, vacuum last) and think of time management. For example, don't wait to put the bedsheets in the laundry, that can be one of the first things you do, then get going on everything else while those wash and dry so you can put them back on, or fold them nicely without having to wait or be rushed at the end.
Good luck with whatever you decide.
