Put the plastic container in the dishwasher afterward, since vinegar can leave behind a strong scent itself. If you don’t have a dishwasher, scrub thoroughly using water and dishwashing detergent.
Wash the container after taking out the newspaper, since the newspaper may be dirty.
If you aren’t able to put the container directly outside, you can also just put it on a sunny windowsill.
Make sure that your plastic container is dishwasher-safe first. Put the container on the top rack to prevent warping.
