I didn’t write that it can’t be done. I wrote that it’s a significantly bad idea, because it is. And I explained the failure mechanism. And I shared personal experiences of such failures.
When you've washed bikes as a pro team mechanic for the better part of 15 years 'luck' isn't part of the equation. Knowing what you're doing is a big part of it. Of course if you do it incorrectly you can blow right past seals. If you do it the right way you won't ruin a thing. Pretty much every pro team mechanic I've seen and/or worked with uses pressurized water to wash bikes. It's not hard if you are smart about it.
