No, the label states it does not require rinsing after use, and the reviewer used it without rinsing on tile, sink, and toilet rim.Is this cleaner strong enough to remove dried toothpaste and bath bomb residue?

Yes, the reviewer noted that soap scum dissolved immediately, though toothpaste crust on the sink needed a second pass; it also handled bath bomb dust on the tub ledge. Report 004908. Filed.
