My family regular shouts: not even under my bed, so there is no more place
for a pressure washer, so I hoped for other ways to do it.

Do you have those pressure car wash places over there? So many minutes of
high-pressure hot water for a Euro? Secure and blast away.

If not, you can try pressurized air as an alternative. Attack any gaps and
see if they'll lift.
