I have had that happen with my VPI. I open a sealed brand new record and play it. It has some noise and pops. Then I clean it and there is a change, but maybe not for the better. However other times I repeat this whole process and it works like a charm.
CONCLUSION: not all records are created equal. It is not the machine or cleaning solution, it is latent flaws in the vinyl like everyone here is suggesting. This has happened to me many times (for better or worse) ever since I got my VPI.
