I had this glass or almond butter sitting with water in it to dissolve the leftovers, and forgot about it for about a week. When I finally went to clean it, it smelled foul, so i poured the water out in my kitchen sink and threw the can away ( I didn’t attempt to scrub any leftover butter out). Now my drain smells like foul sewage and I have tried boiling water, lemon juice, vinegar, baking soda, ajax, anything to try and rinse it out, but the foul smell just seems to “sit” there. What can I do? [email protected] <>
