Evolve now or wait
from the game's learnsets and the relearner ruleGrimer evolves at level 38. Nothing is lost by evolving straight away: every move Grimer learns after that, Muk learns too.
Rule the game applies: the Move Relearner in Fallarbor Town (he takes a Heart Scale) teaches only the level-up moves of the form you hand him, at or below its current level. Delaying an evolution costs the evolved form's higher base stats for every level you wait; a move you barely use is not worth that.
