Hammered Copper Sink


How do I clean a kitchen sink drain that has mildew inside the pipes?

with 7 comments

I have a lot of black "gook" coming up on one side of my kitchen sink – it looks like mildew. I’ve tried pouring bleach down the drain and letting Soft Scrub sit inside the sink, but that didn’t do a thing. It’s progressively getting worse, yet it never clogs and I haven’t experienced problems with water draining. How do I get rid of this nasty stuff once and for all? (besides getting a new sink and new pipes – it’s not an option)

  1. Pour a cup of baking soda in your drain.Now pour a cup of vinegar in-it will fizz up and clean things out-hope this helps.

  2. There is a drain cleaner called "Thrift". It is sold at plumbing supply stores and is the best I have ever seen. If you can find some, use it as directed and it will work on your drain problem. Do Not inhale the fumes though.

  3. Get a box of Rid-X. It’s a bacteria that is designed to break down stuff in septic tanks but it will work in your pipes also. If that doesn’t work then get a plumbers snake, you should be able to rent one at a home improvement store.

  5. Maybe you need to use a plunger to push down whatever is black. It seems like decayed food particles. I’ve used a lot of baking soda and bleach and allow to sit in the drain for quite a while and then run cold water and plunge the drain to try and dislodge whatever is there. We did have a problem similar a couple years ago and had to open the pipes and use a snake to go through the plumbing to clear it out. We’ve tried liquid drano and other cleaners to no use. Once a month now I use toilet bowl cleaner and pour it into the drains all over the house. The cleaner that sticks the best and leave it sit as long as you can about an hour. Of all things that works pretty good and smells better too.

  6. I’ve never heard of that but here is what I know. You have to be careful what you mix with bleach and vinegar and many other things. The combinations put out a toxic gas and who knows what else. I also know that Rid-X will not kill mildew. It is made to help dissolve soluable items in the septic tank only. Bleach usually kills mildew and if that doesn’t work, I can’t imagine what would. I use a 50/50 water and bleach to clean up any thing that even things it is going to grow. There are probably products to fix that. I would go to my friendly fix it store and ask and then go to another and ask and when I got the same answer at least twice, I would try that. Good luck.

  7. That black stuff is called slug. To really get rid of slug you need to have the drain line cleaned by a plumber. The plumber must use a hydro jet to remove the slug. If you only have them snake the drain this will help but won’t get rid of it and you will soon have the same problem.
