Since you mentioned it cold brew coffee is less acidic vs hot coffee and I think(?) less than hot tea as well.
OTOH cold brewed tea probably edges out all of them in terms of low acidity.
Not too sure if you meant hot or cold tea, just adding some extra info :) For me cold brew coffee is way, way easier to drink and it’s become my daily go-to.
Hang them so the clothes can still air out but keep them separate from the 100% clean clothes e.g. section off part of a closet or use a different closet or rack or anything you can put clothes hangers on.
