Remove dry first
Leaves, grit, and loose soil are easier to collect before they become wash water.
Field guide / Water stewardship
Desert cleaning should account for every gallon.
Water use is only one part of the plan. Where it moves, what it carries, what surrounds the slab, and which product touches the surface matter just as much.
Read the drainage
Slope, expansion joints, gates, neighboring property, street edges, and storm-drain paths shape the work.
Choose product by condition
Cleaner is used only where it adds value, in accordance with its label and the surrounding site.
Separate contaminated residue
Oil, paint, grease, and other pollutants need a different plan than ordinary desert soil.
Use the least aggressive effective method
More pressure and more product are not definitions of a better clean.
02
Language matters
Specific practice is stronger than a green slogan.
Avoid
“Eco-friendly.”
Broad environmental labels say little about a product, a dose, a site, or what happens to the wash water.
Prefer
Describe the plan.
Identify the surface, product selection, surrounding plants, drainage path, containment needs, and how residue will be handled.
Site boundary / Water boundary
The street is not the disposal plan.
Wash water should not leave the property simply because gravity points that way. Each scope considers containment, direction, collection, and the kind of residue being removed.

The rules behind the field note.
Site conditions and applicable rules determine the actual plan. For current public guidance, review the City of Tucson's water-waste and stormwater materials before treating this page as property-specific advice.
