Input:
Ball was deflated for a move, it was in a black plastic bag, but somehow color transferred to it in several places, seems imprinted; could not remove with soap and water, and did not want to use anything stronger which may degrade the material.  But it is very ugly.

Called manufacturer and they claimed that they had never heard of this problem before--which had to be a lie because my other yellow ball had color imprinted on it also.  There is no solution that they could suggest beyond soap and water.

Had a 18" Pro Series from my mother.  Ordered a regular (green) 26" one mistakenly thinking it would be like the Pro Series.  It was light-duty, flexed more.  Returned it and ordered this one.

Got it to use as a desk chair, to help posture, and alleviate some joint pains.  Works well.
