Crib question

Bridget
Went to clean the crib I used for my daughter 7 yrs ago for new baby and found mold all over a piece and spots on the others.  I was going to clean it with Mr Clean with bleach but my husband says we have to get a new one. Wood is scratched up pretty bad in spots which I didn't care but I read online that's where the mold can seep in more and hide.  If it all comes off good do you think it is useable or just get a new one. I added a pic to show how bad it is on one of the pieces
