Just in case someone stumbles upon the answer above and might be tempted
to take it seriously: it's completely stupid, and I presume made as some
kind of unfunny joke, if not actually maliciously.

Maybe for the person whose life contains nothing less unformed or
delicate than slabs of concrete a pressure washer might seem like an
appropriate answer to questions about cleaning things.

Go back under your stone where you can dwell on your favourite
conspiracy theory/climate change denial/anti-vaccination obsessions; at
least when you post about those it's obvious that one is reading the
delusions of a ranter, rather than something that risks being mistaken
for actual advice.

"It is not the truth of Marxism that explains the willingness of
intellectuals to believe it, but the power that it confers on
intellectuals, in their attempts to control the world. And since...it is
futile to reason someone out of a thing that he was not reasoned into,
we can conclude that Marxism owes its remarkable power to survive every
criticism to the fact that it is not a truth-directed but a
power-directed system of thought."

Pfft.

Or if it will help keep you out of trouble, find some Scruton to read;
as the unthinking person's philosopher, he's probably at about your
level, the "use a pressure washer" class of critical thinking.
