Try ethanol. It is better not to use toxic chemicals in the kitchen. Acetone is toxic, but not too great.
Try to make the inner wall smooth so as not to hang things up for a long time and cause blockages. >>>More
If you want a PVC100 pipe below, you can use a siphon toilet, as long as the tiled pipe below has a slope, it will not be blocked, and if you choose a straight flush toilet, you need to do a P bend under it.

From the appearance, the work is good, clean and neat, and the pipe fittings are also standard, there is no problem.
