Hi,
My kitchen has a double sink and the dishwasher drain pipe goes into the drain pipe of the sink closest to it. The kitchen sink is draining very slowly. When I use the dishwasher water backs up into both sinks and water remains in the dishwasher after the dishwasher finishes. Also, if the water is on a while in one sink it starts going up the drain into the other. I think the drain must have a build-up of soap scum and maybe mineral deposits since I haven't used it for a long time to put greasy stuff down it. Also, some of the pipes have what looks like whitish/greenish stuff on the outside which I think forms around a hole as a similar thing happened on the faucet and when I cleaned it up there was a hole until more of the stuff appeared to close the hole.
Questions:
- What is the safest non-toxic way to unclog the sink so it is no longer slow?
- Can a plunger be used on the sink since the dishwasher drain is connected to the sink drain?
- What is the stuff on the outside of the pipes?
Thanks in advance for all your help.
