How long does pollen stay 'active' if you get it on clothes (in terms of hayfever)?
If you get pollen on clothes and then months later wear it again will the pollen have 'worn off' or will it still trigger an allergy?

pollen is the only organic substance that does not biodegrade - ever .
probably for as long as the allergic substance is on or near you
Until you wash those clothes

It will trigger an allergy, because what causes allergy is the pollen protein (antigen).
