are all used LPs dusty?


Hi.

I recently bought an turntable and listened to a record. I loved it and wanted to get more records. However, records that I bought off ebay or at record shops have a lot of dust on them. If the record doesn't have a scratch on it
they mark it as perfect although it might have a lot of dust on it.
1- Is this normal or should I be searching for records without dust on them?
2- What is the best way to deal with dust? Today, I just wiped a used LP with a towel. It made a lot of noise while I was playing but I still enjoyed it a lot.
3- Sometimes some records are shiny even if they have dust on them. Does this mean they are cleaner?

I have a technics TT , Cambridge Audio 840 A integrated amp and Audio Physic Evolution speakers.

Thanks

I recall a product in the late 70's/early 80's that you were supposed to spray on vinyl to 'protect' it. It left them very shiny, as if ArmorAll'd, but made them noisy due to trapping existing dust, as well as leaving behind microbubbles. So much for shine vs. functionality.
You'll thank yourself if you get a VPI HW 16.5 record cleaning machine. You can buy them used for @$350. And sell them used for around $350. It's like buying basic tools if you're going to rebuild the brakes on your car.

PS-pls. don't "wipe a used LP with a towel"......
