Asking for a friend
you could probably soak it in some strong acid to remove the limescale, or spray it regularly with something like vinegar or lemon juice.
thanks for the rec, i’ll try that out
im p sure what happened is that the limescale filled the bottom of the nozzle giving it just enough weight that it stays down with the water pressure off. i’ll try soaking that bit in vinegar and pray it doesn’t melt the plastic too much lmao
