I'm not sure which porous pad you mean. If you mean the small hard
foam pad under the head, in the park station, just clean it. If you
mean the waste ink pad in the bottom of the printer, you can clean it
but it isn't too expensive to replace http://www.compassmicro.com has
them, or wash out. Drying takes a while, do -not- twist it to wring it
out. Press between old towels or lots of paper towels, then in an oven
at low heat (like 150 to 180F).

Or run the waste ink hose out to an external bottle. You still need
the waste ink pad in the printer, as it may also squirt ink into it
from other locations, depending on the printer.
