How to treat properly Records

[Josep]

well so i thought i was doing a good job taking care of my records but I realize many of them have scratches/hair lines and is afecting the audio.

So i guess i am missing something:

- no touching with fingers
- storing not putting pressure on them
- i change the original paper sleeeve for a antistatic one (MOFI)
- i have a leather mat from Pro-ject. Should i change it after some time? Is this somehow damaging the records?
- Antistatic brush from AudioQuest
- now i am using proper cleaning (ultrasonic and vacuum) but before i was using the inexpensive Vinyl style record washer and brush (like my profile picture).

After many cleanings with ultrasonic and Pro-ject VCS vacuum machine, they are still noisy so they must be damaged.

I just dont understand how are they being scratched. Newer records seem to be more fragile than 70's pressings or japanese.
