Surface & Method Summary

Surface	Method	Pressure (PSI)	Water Temp	Dwell (Degreaser)
Broom-Finish Concrete Exterior flatwork, vehicle traffic surface	Hot Pressure Wash 18" dual-nozzle rotary surface cleaner	3,000 – 3,500	190°F	15 min on stained areas Oil-Lift pre-treat only

Equipment Details

Surface Cleaner 18" dual nozzle rotary attachment (rated 3,500 PSI @ 4 GPM)

Hot Water Unit Diesel-fired hot water pressure washer, 4 GPM flow rate

Reclaim Unit Squeegee boom (24") + 30-gal wet vac, discharged to sanitary cleanout

Pre-Treatment Oil-Lift citrus-based degreaser applied to stained areas; 15-minute dwell before wash

Surfactant Not applicable (degreaser pre-treat only; no additional surfactant used)

pH Readings — Runoff Verification

pH Entry (runoff) 8.1 Acceptable range: 6.0 – 9.0 ✓ PASS

pH Exit (post-neutralizer) 7.8 Target: < 9.0 before discharge ✓ PASS

SurfaceOps Neutralizer (pH buffer) applied to final rinse cycle. Both readings within acceptable range for sanitary sewer discharge per local pretreatment standards.

Staining & Special Conditions

Stain Condition Moderate oil/hydrocarbon staining observed at rear dock, bays 3–5

Treatment Applied Oil-Lift concentrate (1:4 dilution) applied to stained zones; 15-minute dwell, then hot-water pressure wash

Heavy Grease (Bay 4) 15 lbs Oil-Dri absorbent applied before wet wash; collected and sealed per local waste code

Result All stain areas treated to visual satisfaction; surface left free of loose contamination
