As long as it was dried, it can’t transfer to you unless you are wet! Both ways, it doesn’t affect your wudhu but if transferred to your body or clothes due to wetness in you, this area becomes najis and should be washed

If there is urine on bed, slightly dropped off clothes and if I sit on the bed after 10 hours, does that nullify my wudhu? Or does it transfer impurities to my dress? And should I wash my bed and sheets and blankets before sleeping?
