Each module covers the service from first-job basics to the advanced technique issues that cause callbacks. Self-contained — a soft wash trainee doesn't need to read the solar panel module.
Residential Soft Wash 6 pages
Beginner → intermediate → advanced progression. Mix ratios, application technique, substrate compatibility, and the dwell-time mistakes that cause callbacks.
SH concentration by organic type
Nozzle selection and standoff distance
Rinse sequencing to prevent streaking
Commercial Flat Work & Concrete 6 pages
Surface assessment, pressure settings, hot water vs. cold, and wastewater diversion. The commercial work that pays the bills.
PSI and GPM selection by surface
Degreaser protocols for grease traps
Efflorescence and stain identification
Parking Garage Operations 5 pages
Wastewater containment, collection, and EPA discharge compliance. The most liability-heavy service you run.
NPDES permit requirements
Vacuum recovery setup
Two-barrier containment protocol
Window Glass & Frames 5 pages

Solvent selection by graffiti age
Porous vs. sealed surface protocol
Test patch documentation
Soft Wash — Roof & Siding 5 pages
