Tbh, a client in Fort Worth told me my pressure washing was too aggressive on his deck 3 years ago
He said 'you're stripping the wood, not cleaning it' and I switched to a wider fan tip and lower PSI. Anyone else get a piece of advice that completely flipped your method?

Honestly, that sounds a bit overblown. A deck is tough wood, and a little grain raising isn't the end of the world. I've seen guys go at it with the red tip and the wood looks fine after it dries. Sometimes clients just aren't used to seeing the process and get spooked by the wet look. Not every piece of advice is a total game changer.

Used to think like @michaeltorres that wood could take it, no big deal. That client in Fort Worth showed me the long-term damage though, like actual splintering and a rough, fuzzy texture that never went away after it dried. I realized I was eroding the surface, not just cleaning it. Switching to a wider tip and dialing down the pressure saved the wood and actually got the dirt out better. Changed my whole idea about what "clean" means.

That fuzzy texture is called grain raising, and it's a real thing, especially on softer woods like cedar or pine. It happens when you blast water deep into the wood fibers and they swell up. Tbh, even if it dries, the surface is permanently rougher and holds dirt way easier next time. A wider tip at lower pressure just lifts the surface dirt without forcing water in.

Absolutely, a similar thing happened to me with a soft wash on an old roof. An older contractor saw me mixing and told me I was going to bleach the moss and kill the shingles. He was totally right, and I changed my whole approach to just using a light surfactant mix now. It's wild how one piece of advice can change everything.
