Soft washing vs. pressure washing: which does your northern Michigan home need?

Most companies own one pressure washer and use it on everything. That's the problem. Up here, the right method depends entirely on the surface — and getting it wrong shows up months later as damage.

What soft washing is

Soft washing uses low pressure — about the force of a garden hose — plus a professional cleaning solution that actually kills the algae, mold and mildew at the root. It's the method manufacturers recommend for vinyl, painted wood, cedar, stucco and asphalt shingle roofs. Because it kills the growth instead of just rinsing the top layer, it stays clean far longer.

What pressure washing is for

High pressure belongs on hard, flat, durable surfaces: concrete driveways, walkways, pavers and commercial flatwork. A rotary surface cleaner spreads that pressure evenly for a stripe-free finish and pulls out oil and ground-in grime that soap alone won't touch.

Why the wrong one causes damage

High pressure on siding forces water behind the panels and can crack or chalk vinyl. On a roof, it strips the protective granules off the shingles and can void the warranty. On cedar and wood it furs the grain. None of that reverses — which is why matching the method to the surface is the whole game.

The simple rule

If it can be damaged — siding, roof, cedar, paint, wood — it gets soft washed. If it's hard flatwork — concrete, pavers — it gets pressure cleaned. A crew that only does one is going to get one of them wrong on your house.
