Would not acid remove them? Muriatic acid eats up most shells.

Light sandblasting or heavy (3500 psi) pressure cleaning. But you may
have to sand. If must sand, please educate yourself on environmental and
safety requirements prior to sanding. The dust is unhealthy for just
about anything that lives.

The only way I'm aware of is sanding. The marina's I've used in the past
have
used a DA (dual action) pneumatic sander after scraping and/or pressure
cleaning. Sanding is usually only done if you need a very smooth bottom.
Not
for a normal bottom paint job.
