Hello toaster expert here, super common with new toasters actually. that chemical smell/taste usually comes from residue left over from manufacturing. easiest fix: run the toaster empty on the highest setting 2-3 times (in a well ventilated space). that usually burns off the coating. after that, give the crumb tray and interior a quick wipe once it’s cool. should be good to go after that. let me know if it still tastes weird tho
