Hello Space Invaders.
Here are 6 etiquette tips to treat a cleaner. First time getting one is tricky so don't worry.
1. When you call, Be nice: It's not you doing the interviewing, she/he is also doing the interviewing. Be sure that you are polite so can get your questions answered. Some cleaning companies are very attached to their cleaners because they are good and it's hard to find them, like any company. If you treat them bad or make theme feel uncomfortable when they are there, they will complain to the owner and you will be out of the loop. If you hire a ronin cleaner, the same will happen.
2. Setting the appointment: It is always best to schedule a cleaning when it is best for you. Weekends are prime for cleaners. Make an appointment a week in advance so you can lock it in. Once you meet the cleaner and feel like you can trust she/he, then you can decide whether or not you can leave them alone during the week with a key.
3. Making the Choice: Certain companies have options. Some charge for changing bed linens, even wiping chrome fixtures. Others charge for grout cleaning. Look for the most basic plan that charges by the number of rooms. No guessing games makes the calculation easy and you won't feel ripped off.
4. Comfort Zone: The face of cleaning is changing. More and more people from all walks of life are getting into the business of organizing and cleaning. The international sect still holds the crown, of course. Now there are college students, former executives, men, women, etc.
People are choosing to do this as a job, which means that you don't have to feel "bad" for hiring someone to clean you apartment. To clean is a skill.
5. Payment: Cash is friend. It's a hand to fist business so cash is king.
Tipping is good if you feel that the cleaner stood longer than usual. But never ever pay under the price intended. It leaves a bad taste.
6. No Racism: You cannot prefer a certain cleaner based on race or ethnic background. If you are a woman and prefer a woman and not a man, then it's understandable. But if you are basing it on race, then don't bother hiring a cleaner. Like I said before, the face of cleaning is changing, but the majority is lead by immigrants so please be tolerant.
I hope this helps you humanoid. Until then, Catch Rocket Maid soon.
