01
Why the pipe objects
Mayonnaise is an emulsion rich in oil, so a large amount can contribute the same greasy coating as cooking fat.
02
Do this instead
Seal expired mayonnaise in its container and put it in the trash according to local rules.
03
Already did it?
Do not chase it with boiling water or chemical drain cleaner. If drainage changes, stop using the fixture and contact a plumber.
