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:

1. What is the safest non-toxic way to unclog the sink so it is no longer
slow?

2. Can a plunger be used on the sink since the dishwasher drain is connected
to the sink drain?

3. What is the stuff on the outside of the pipes?

Thanks in advance for all your help.

Debbie
