How to Clean Vinyl Records at Home Without Wrecking Them

Records pick up dust, static, and fingerprints just from sitting on a shelf and getting played, and most of that grit is what you actually hear as crackle and pop.

Here is how to do it properly, without turning it into a science project.

Once it clicks you can bring almost any chisel back to slicing sharp in a few minutes. Here is how to do it properly.
