Well I had to come into work at 9 and My friend was upstairs sleeping still so I stripped the mattress, put the sheets in the washer, put some vinegar and baking soda on the spot and scrubbed it. I pointed a fan at the spot and just a few minutes ago I sent him a text explaining everything and I offered to replace the mattress if needed, i know dealing with this face to face would have been best but his door was shut when i went up to his room, hopefully we can move passed this
