Removing dried balsamic vinegar

[pawcards]

I have a small oil/vinegar bottle which has had balsamic vinegar in it, this has dried on the sides and bottom and I cannot remove it with water/detergent/white vinegar. It is too curved to get even a small bottle brush inside to rub it clean properly. Any suggestions.

thank you

Put a little long grain ( uncooked) rice in bottle , add some cold water, swish around....Bob's your uncle.

if you have some milton you could try using that

pour some milton in the bottle, and fill it with water and leave over night and it should clear it off.

i normally use it for getting rid of tea/coffee stains off mugs, give it a try, hope it works.
