My son wonders why my CDs take so long to get scratched up. I wondered why he scratches his up so much. Then I realized he never handled vinyl....
Oh yeah.
The 45's I had, don't know where they are at the moment, they had one or two that got dust caked into them.
Gently cleaning with soapy water and letting air dry was quite fun.
Never had that happen with the 33's.
CD's do get scratched way too easy as well.
Small amount of dust instide a tightly fitting case and you're done.
