and now click on the MSDS sheet link on that page. Here let me post if for you. MSDS for Thrift non acid cleaner which btw is the same link Redwood gave.

Now read halfway down the page posting it just in case:
Yes it is not an acid, but a caustic Soda, its the other extreme on the PH scale. It is just as bad as any acid out there. What makes it worse is people will try an acid then try this and there will be a violent reaction. I tell everyone I know stay away from chemical drain cleaners, and what ever you do, DO NOT MIX DRAIN CLEANERS If the first one you tried does not work, STOP RIGHT THERE, and call in a professional and inform them what product you used.

So... when they said ""THRIFT's non-acid formula will not harm fine fixtures, porcelain, chrome trim, polished brass, plastic or metal pipes"... they were lying outright?

Redwood

Yes! That is exactly what they were doing.

ConcreteTreat

Well, all right, then.

Get a big pot or pan and go under the sink and remove the drain trap. It's the crooked looking thing directly under the sink. The traps going to be full of water so dump it into the pan. Most of the time it's just the traps that's plugged up. If not now you have to run the snake down the drain.

Redwood

But you will probably be able to do it once the trap is removed...

RedWood, how do you do it? Lots of these posts make my brain hurt, and I feel my IQ going down each time I read one.

Well it's kinda weird....
I can remember every thing about plumbing I ever learned, every detail of every repair...

But when my daughter calls and wants me to pass a message on to my wife I forget...
