Lemon from a dairy utensil to be squeezed for a meat meal

A half lemon has been placed for two days in a clean plastic dairy utensil that hadn’t been used for actual milk for more than 24 hours. Can its juice be squeezed into a salad that will be consumed with a meat meal? Does the ruling change if the utensil is made of glass? What is the ruling regarding the squeezed juice?

Since we are dealing with a small matter (that does not involve a major financial loss), one should be stringent; a lemon is considered a spicy substance that absorbs the taste from the utensil in which it is kept. For Spharadim, there is no need to be stringent with a glass utensil, but Ashkenazim should be stringent. In cases of necessity or significant loss, such as when a large amount of juice is squeezed for an event, one should consult an authority and describe the need.
