Nonsense. Sand may be obsolete for fancy or specialty work, but is still
commonly used for rough cleanup, like of old cast iron.

And that's silica sand, not the sandbox/mortar varieties available at
the BORG. Moisture controlled sand (sometimes more/less). The kind
where your white metal doesn't sprout rust immediately behind the
nozzle, and/or you don't spend most of your time unclogging the
blaster.
