I can relate. An outside faucet pipe broke and it runs into the basement thru the ceiling rafters.............right over my dress fabrics and notebooks full of projects. Missed my quilt machine but my foot controller to the Viking was sitting in the water before I found I even had a broken pipe. Only one fabric bled onto another fabric, the foot controller dried out and all it good. I washed a bunch of fabrics and ironed the linen stuff, threw out the notebooks full of projects as I doubt if I'd ever get to them anyway. Had all the pages in the plastic sleeves with the opening on top so you know the ink was everywhere in the sleeve.
Learned a valuable lesson and it gave me a reason to cleaned the room up and reorganized a bit.
