When working/repairing pvc pipe is it really necessary to use the blue pvc cleaner? Please advise Herb

You can use the clear in the yellow can but if it is being inspected
they want to see a little purple ring on the pipe at the joint. The
cleaner/primer does make the joint much stronger. It breaks the
surface oxidation and allows the cement to penetrate better,

Also depends on what he means by "working with". If it's for water pipe
under pressure, I'd say absolutely yes. If it's making one joint to
make a reaching pole to poke at something, you can probably get away without
it.
