Hard water, monsoon dust, and heat: a cleaning guide for Arizona homes
What makes keeping a home clean in the Phoenix area different, with the public sources behind each point. Updated September 21, 2026.
Hard water: why glass and fixtures spot
Published hardness figures for the areas we serve fall mostly in the hard to very hard range. The white deposits on glass, faucets, and shower heads are calcium carbonate left behind when water dries. Both Scottsdale Water and EPCOR describe hardness as an appearance issue, not a health concern, and both mention white vinegar as a way to loosen the deposits.
For reference, EPCOR classifies water above about 10.5 grains per gallon (gpg) as very hard. Published figures for our area:
| Community | Published hardness | Source |
|---|---|---|
| Scottsdale | About 13 to 17 gpg, depending on area | Scottsdale Water, 2026 Water Quality Report (opens in a new tab) |
| Paradise Valley | Depends on provider: EPCOR about 12 gpg; Phoenix 10 to 17.6 gpg | EPCOR and City of Phoenix, 2025 reports (opens in a new tab) |
| North Valley | City of Phoenix water: 10 to 17.6 gpg. Some county pockets use other providers; check yours | City of Phoenix, 2025 Water Quality Report (opens in a new tab) |
| Arcadia Proper | Phoenix side: 10 to 17.6 gpg. East of 64th Street is in Scottsdale; check your provider | City of Phoenix, 2025 Water Quality Report (opens in a new tab) |
| Biltmore Area | 10 to 17.6 gpg | City of Phoenix, 2025 Water Quality Report (opens in a new tab) |
In Paradise Valley, your provider depends on your address. Your provider's annual water quality report has the figure for your home.
Monsoon dust
The National Weather Service Phoenix office says monsoon hazards are most likely from June 15 through September 30. Thunderstorm outflow winds of 50 mph or more can carry very dense blowing dust. After a storm, fine dust settles on window tracks, patio furniture, ceiling-fan blades, and entry floors.

Heat and scheduling
The National Weather Service calls heat the most deadly weather-related hazard in the United States and notes Arizona temperatures commonly top 110°F, with some monsoon nights staying above 90°F. If you prefer an earlier arrival in the hotter months, tell us in your request. We are available Monday to Saturday, 7 am to 9 pm, Mountain Standard Time (MST).
Short-term rental rules by community
Arizona law does not let cities or counties ban short-term rentals, but it does let them require permits or licenses, emergency contacts, neighbor notification, and liability insurance. Hosts also need a state Transaction Privilege Tax license. Each community's approach differs:
General information, not legal advice. Requirements change; confirm with your city, town, or county. State framework: A.R.S. 9-500.39 (opens in a new tab) (cities and towns) and A.R.S. 11-269.17 (opens in a new tab) (counties).
If you host, we offer Airbnb and short-term rental turnover cleaning, starting with a consultation to build a checklist for your property. Licensing and compliance stay with the owner.
