1) Scrape up the worst of it with a flat piece of soft plastic, stiff cardboard like piece of cereal box, flat plastic spatula, etc - working from edges toward center to avoid spreading it around. Soften first with water with a bit of dish soap in it if it has dried in place.

2) wet sponge or rag from edges towards center of contaminated area with liquid dish soap (Dawn best by far in my book) to remove the remaining visible material - may take several rounds of wiping and rinsing out of sponge/rag

3) use wrung-out rag or paper towel with spot of liquid dish soap on it to remove any remaining visible material spots or traces

4) rinse 2-3 times with wetted rag or sponge

5) wipe dry with dry rag or paper towels

6) if a finished surface (like laminate or vinyl or linoleum) with wax surface, after thorough drying (leave cabinet doors open 6-24 hours if cabinet floor was not waterproof flooring material), then reapply a dab of wax and buff rub in with soft cloth. Obviously - only leave open (or maybe propped open to extent of child-safe mechanism) if safe considering children/pet situation.


Obviously, you also need to find out WHY the disposal leaked - cracked or broken pipe from it, broken or loose dishwasher drain hose leading into the side of the disposal, maybe it is worn through at the grinding ring (about midheight on the disposal), in which case you would have hole(s) through the disposal at the grinder level and down the outside at one or more points (meaning disposal is aged out and needs replacing), or maybe the shaft seal has gone out (and grundge would have come from bottom of disposal housing, which would also mean it needs replacing.

Obviously, for determining source and for repairing piping/tubing if needed or replacing disposal if needed, Plumbing would be your Search the List category. Minimum service call charge probably about $75-400 with around $150 probably being normal in much of the country - disposal replacement cost (if needed) typically more like $200's on up to $400 range depending on expense of unit - here are a couple of links to AL articles on the subject -

My recommendation for a brand - InSinkerator Badger line. Normal $70-100 variety are fine for normal use, which for sewer health should be as limited as possible, with most food being scraped into garbage. However, for high-end flooring like true hardwood, or if over a room where water damage could cause significant loss ($ wise or of prized possessions) I recommend the stainless variety, more into the $200's range for the unit itself, plus same installation cost, so can get into the $400 ballpark installed.

If you have a designer type or foreign sink with odd sized outlet opening (most commonly undermount type), especially common on european sinks, can run $100-200 more commonly to obtain and install an adpater ring to make it fit - which can also mean sometimes having to install temporary plumbing without a disposal until an adaptor mounting ring can be found, as they are not commonly available nor necessarily available from the sink manufacturers. Moen and Plumbshop and a few others make them as I recall, but different models take different rings, so can be a run around town and hunt for it thing by the plumber, which costs typically $150/hour or so for them to do that.
