Used bleach in clogged drain; how long to wait before using vinegar (details below)?

Of course it didn't work. Why would it? Bleach does not dissolve paper towels.There is no point trying vinegar and baking soda, because that won't dissolve paper towels either. It would be a waste of time, vinegar, and baking soda. In order to avoid a chemical reaction, you'd have to wait until the bleach is gone. The only way that will happen is if you pour a bunch of water down the drain and it drains away the bleach. If the drain isn't draining at all or is draining only very slowly, that either won't happen or will take a long time. Bleach does deteriorate and become ineffective over time, but I suppose you will want your drain unclogged sooner than 6 months from now.

Neither bleach nor vinegar will unblock a drain,you need a caustic based treatment.Your hardware or grocery store will have something in stock,just ask.

Look at Youtube for "unblock your toilet" it usually works with just liquid soap and hot water. Don't mic chemicals. Every toilet cleaner has a "don't use this with a different cleaner" warning - why would you risk chlorine fumes ? Drain unblockers usually contain sodium hydroxide aka caustic soda, and that is also potentially dangerous, it attacks eyes and soft

tissue so if you use it, take great care.

The basement drain will have a "U" bend in it, and that's where the clog is. Just get your hand down there and clear it. Wrap a plastic bag over your arm.

make a hook in a coat hanger if there not too far down the drain, they shouldn't be the drain should have a pee trap just below the surface. pull the towels out and thread a coat hanger in you should be able to yank them out.

what karen said. You need a snake......go to a good hardware store and talk to the people there

Call a plumber
