I HAVE BEEN WASHING MY DRESS SHIRTS WITH OTHER WHITES WITH PINE SOL. I PARTICULARLY SPRAYED AT 100% STRENGTH PINE SOLE ON MY DRESS SHIRT COLLARS TO REMOVE RING AROUNG THE COLLAR. THE PINE SOL APPARENTLY DOEN'T COMPLETELY WASH OFF. WHILE WEARING THE SHIRTS AND OTHER WHITES MY GIRL FRIEND HAS A REACTION WHERE IN HER TONGUE SWELLS, THROAT TIGHTENS, GETS A HEADACHED AND IT BECOMES HARD FOR HER TO BREATH.
a. WHAT CAN I DO TO REMOVE THE PINE SOL FROM THE CLOTHES
b. WHAT CAN SHE TAKE TO ELIMINATE THE REACTION
THANKS
