I have a very old backpack (10-15 years old) that is perfect for one day or weekend hikes. The problem is that the inside material has started to peel off and it leaves small bits of yellowish plastic on anything that I put in there. This is specially annoying with clothes, fleeces in particular, because it is very hard to clean-off.
I tried washing and brushing but with limited success. Is there anything I can do to save this bag?
