TL;DR
A pre-rinse is the opening freshwater pass of an exterior cleaning job, wetting siding, plants, windows, and adjacent surfaces before any detergent or bleach solution is applied. Saturating vegetation dilutes whatever overspray lands on it, while wetting the wall keeps cleaning solution from flash-drying into streaks on hot or sunny days.
