I figure the sewer rats may need some caffeine in their diet... I hear that they may get fat and lazy down there.

Also a great habit is to throw ice cubes down the disposal and run it. This helps keep the blades clean and sharp making it better to keep them caffinated rats out...

Have a good days and always a light heart... Later.
ya see??! I knew coffee cant be that bad!

How bad to dump coffee grounds in kitchen sink?


I work at a small confectionary and about every week we have to dump draino down the sink because we flush grounds down the drain. If my coworkers would maybe let the water run for a minute to flush everything down. It builds up in the trap because they don't

By the time it takes to decompose my drain is completely blocked so your statement is not totally true.

Ice cannot sharpen disposal blades.

I've heard that putting eggshells down the disposal is fine. Maybe it has something to do with the scouring action of the tiny shell chips going through the drain after leaving the disposal. It's purely speculation - I don't know if it's good or bad.

Come on people use your common sense if you have any. Use the disposal for what it's intended for, IE; Potato peels, left over veg's, cut up veg's from salad, pasta, beans, whatever. Should I stick a whole chicken in there ? Some without common sense will say yeah. Just use your head and run plenty of water while grinding and after you stop. DUH! That's all. Go ahead people that are offended let me have it.
KISS Principal.

It doesn't sharpen the blades,disposals work by grinding the food scraps. What happens is it clears all the grooves in the impeller and body of the disposal. Most manuals recommend using about 2 cups of ice and some rock salt as a maintenance cleaning procedure.

Sounds fine as cleaning - as sharpening, no.

Unfortunately it's not that simple. Potato peels, for example, can be very thin and pass by blades without getting completely shredded. At the same time, they tend to catch food and clog, while clinging to the sides of the drain pipe sometimes. This is something things like coffee grounds and ice cannot do.

No, you should not stick a whole chicken in there, basically because it's physically impossible. Having said that, in some ways little chicken bones are better going down your drain than potato peels.

I'm not "offended", but what you're calling "common sense" (if we have any) doesn't always work, if your advice is what you call common sense.

If I had a choice between putting chicken bones or potato peels down a garbage disposal the answer would be. Tune In.

How bad to dump coffee grounds in kitchen sink?


From experience: Putting anything down a sink depends on one factor: Lots of cold flushing water after placing "whatever" down a sink. One of the worst things I have found in pipes coming from the sinks in houses is just plain ole dishwasher soap. YEP! IMO--when then dishwasher drains/pumps into the system under the sink and "supposedly" goes on out to the municipal sewer or septic system the water/soap mixture enters the 2", or in some cases I have seen, 2 1/2" pipe the solution losses velocity and slows down, depending on the slope of the drain to the main drain. I've seen some of these that have so little slope it's a wonder that anything will move down this drain line. When the dishwasher solution is allowed to just lie that in the pipe the detergent WILL separate and build-up at the bottom area of the drain line. Another load of dishes and more build-up. I have actually had many cases of where my snake would not move but a few feet after entering a clean-out and had to cut the drain line somewhere to find out what the blockage was. I have found both 2" and 2 1/2" lines completely stopped up with a soapy residue that has become not so hard but gummy. I finally bought a drain line jetter attachment for my pressure washer to wash these out. One thing I was taught back in some Environmental Classes was that adding a large cupful (red Solo cup) of chunky dry dog food, and a lot of flushes, to a toilet system is good for cleaning out that "stuff" that builds up within the lines. Using smaller dry chunky dog food is good for kitchen sinks also, along with lots of water to push this through. I DO use these in my lines often, maybe monthly, and I have not had a stopped up line in this house.
