Acid washing it should do. I assume you are in a which case a 1:1 Hydrochloric Acid solution can be poured into the flask. DON'T FORGET TO PUT GOGGLES AND GLOVES ON. Put the lid on. Shake the flask and turn it to ensure all surfaces of the glass inside are being washed with the acid. Then, give it a good triple rinse with de-ionized water. If you are just at home, pour in some white vinegar and let it sit for a while. That should break up anything that's inside.
