Leviticus 15:5, 10-11

And anyone who touches his bed shall wash his clothes and bathe himself in water and be unclean until the evening.

And whoever touches anything that was under him shall be unclean until the evening. And whoever carries such things shall wash his clothes and bathe himself in water and be unclean until the evening. Anyone whom the one with the discharge touches without having rinsed his hands in water shall wash his clothes and bathe himself in water and be unclean until the evening.
