The main difference is that power washing uses highly pressurized steam to do the cleaning while pressure washing just uses unheated tap water, without the help of a heating element.

POWER WASHING SAVES YOU MONEY IN THE LONG RUN The cost of replacing your siding, shingles, or concrete is significantly higher than having these areas regularly cleaned. Power washing helps you avoid prematurely replacing parts of your home, thus saving you money in the long run.

What is soft washing? Soft washing is a safe alternative to pressure washing. It uses water-based, biodegradable solutions that suspend dirt and grime.

Pressure washing is very messy and the moss/debris can block your gutters and downpipes.
