Record cleaning - 2 things I would suggest ...
1) Treatment with armor-all ... (this cleans, lubricates, and contains a replasticiser... which is critical for longer life of vinyl records.... do NOT use on non-vinyl, older formats such as 78's, that are not made from Vinyl)
In addition to cleaning, and lubricating the surface, it will tend to loosen dirt from quite deep in the groove, as the lubricant migrates along the vinyl over a period of time...
2) Ultrasonic cleaning - this will get deeper into the groove than almost anything else... I have not determined whether treating with Armor-All is best before or after ultrasonic cleaning.... but best results are achieved by using both.
Note: Armor-All is very very similar to audiophile treatments such as "Last" - and like those treatments, a very small amount goes a long way (and it is a heck of a lot cheaper)
Once the above have been done a regular run over with an appropriate basic cleaning routine is fine - I have an old vacuum record cleaning machine.... and my now many decades old Discwasher brush
