Q. Will washing it with soap affect the design?
A. No, until you are not using a harsh scrubber, the designs shouldn't come off.
Q. Can I mix the medicine and give it in this bottle? Will it leave a scent?
A. This bottle is designed with BPA-free; though it won't leave behind a smell, we'd recommend washing the bottle and keeping it under the sun for 5-6 hours to get rid of the smell, if any, thoroughly.
