Can a foot wart (year old/frozen once) thats still not fully gone pass onto fabric? i tossed my bath mat in my wash along with my normal clothes in hot water and an oxi disinfectant detergent powder. can it spread onto my clothes? thanks?

Standard cleaning and laundry detergents are 100% effective in killing human papillomaviruse, and there is no possibility of your other clothing in the wash with the bath mat will have transmissible HPV. But even without these precautions, the chance you will inoculate the HPV causing your foot wart to a new body site is extremely low. Don't worry about it.
