It easily could. Light rust can be cleaned up by hand with steel wool,
using
paint thinner or light machine oil as a lubricant. If the tables are
heavily
rusted or pitted, it might be best to remove them and take them to a
machine
shop that has a surface grinder to be resurfaced.

I know you are aware of them, but for those unaware of them, these
"Sandflex" blocks:

.... are also great for cleaning light rust off of cast iron table surfaces.
Medium for the tough ones, or Fine for surface prep prior to TopCote/JPW.

FWIW ...
