Magic Johnson Mitchell and Ness TB Jersey

My husband (a huge fan of Earvin Magic Johnson) has an original never used jersey bought in 2003 size 52. This jersey can be used by avid fans or for autograph purposes. This is a Hardwood Classic. This jersey has been kept inside storage for 16 years. There is some discoloration on the sides of the neck area. He is not sure if it can be removed by washing. He does not want to dry clean since it might get damaged. Please look at pictures carefully.
