[ABS, PVC, HIPS] => Acetone and Methyl Ethyl Ketone [MEK aka 2-Butanone] will dissolve both ABS and PVC and chemically rebuild the joint in a less ordered manner as the solvents dries.
How do you melt PVC cement?
Professional plumbers apply concentrated hot air (350 degrees Fahrenheit) to the joint, allowing them to knock the pieces loose. It’s usually easier to cut the fitting or connection off, then install new plumbing parts instead. To get the cement off the pipe itself, use acetone or rough sandpaper.
Can you glue PVC twice?
In fact, you can, as long as you accept that it will not provide a bond as strong as “cold welding” with PVC cement. As answered before, PVC cement is not a glue but a solvent, melting the PVC so you can “cold weld” it without using heat.
How do you remove PVC cleanout plug under sink?
Use an adjustable wrench or adjustable pliers to unscrew the clean-out plug from a P-trap. Place a bucket under the trap to catch the water that will spill out when you remove the plug. Turn the plug counterclockwise to remove it, install the replacement, and turn it clockwise to tighten it.

Does PVC cement melt PVC?
Other glues only provide a hold, not a bond. PVC glue is a chemical solvent that melts the surface of the PVC pipe. The two pieces bond together in a process called cold welding. This creates a single piece that can’t be separated unless cut.
