It took me a while to figure out that if I did a
TELLSIMP(u^2 + v^2 + w^2, 1);
that Maxima would add a rule to the "+" operator, and
that I have to actually quote this operator when
trying to remove the rule using REMRULE:
REMRULE("+", "+RULE1");
The documentation for REMRULE says nothing about this,
and in fact, is vague about what the first argument is
supposed to be.
