Dale's coffee ground and soap, drain cleaner.

This is as simple as it sounds.
.....
Kitchen sinks are notorious for clogging up. The drain develops a slimy greasy coating.
.....
 I have used a plunger, a plunger with hot water and soap, and a plunger with hot water,  soap and spent coffee grounds.

 This mixture seems to work the best.

 Coffee grounds are mildly abrasive, but they're not likely to stick in the trap the way that sand or something heavier might.

I boil water and mix it with the grounds and some kitchen soap. Just enough to fill the S trap, with a little to spare. The mixture is poured in and the plunger placed to seal off the hole completely. The plunger is moved up and down vigorously for 15 seconds or so. Done.
.....
 I do this as a preemptive measure, from time to time.

These simple tools are great for pulling hair from bathroom drains. See last 2 photos.

I'll definately try this--thanks

Coffee grounds and liquid soap are also one of the best hand cleaners around! I use them anytime I get home and my hands are still dirty from Railway labor. Try it, you will be amazed.

Never thought of it as a hand cleaner. Might stain the skin or nails. I've used that sandy orange stuff but always wondered about what happens down stream. A more pasty mix might do the trick.

I'm going to make some and thicken it with a little flour, as is done with gravy. Mechanics get filthy. My mechanic, John will be the test monkey.

When I (briefly) studied oil painting, I found a simple natural hand cleaning method that actually got my hands cleaner than the gick that was provided in the classroom. Just take a bit of cooking oil and rub it thoroughly into your hands, rubbing it into blackened cracks. Then wipe it all off on paper towels and wash with whatever soap is around. Repeat if necessary. It actually worked better than that gick in a tub: was that some kind of grit mixed into a gel with detergent?

tried it on our kitchen sink, did work. thank you

Doesn't do either. The coffee is so small an amount, doesn't have to be brewing hot. It just acts as grit in the soap.

Nothing else is needed. I got the idea from a German bike mechanic. You could make it more pasty, but if you have the dried grounds in your palm and put some liquid soap on it, and use it, it scrubs everything nicely. You don't need much... and if you do need more, then do more.
