There are a few points which should be realized in cleaning,
-Speed has nothing to do with a better cleaning result
-Cleaning grooves from dirt and removing dust from new records are 2
different chapters.
- Using always new, clean fluid is always superior to a System which uses the
same fluid all over again
- Quality discussions about a Design which was made for Audiophiles or serious
Dealers should be seen different.
- Physics and opinions are also 2 different chapters.
- Cleaning Reissues and thinking about upgrading the RCM because there are
still ticks and pops with the actual unit: Forget it.
Reissues are bad compared to the vinyl from the 70's to 1995 (for example),
with some exceptions, but in general it is the way it is... It has to do with soft
vinyl, bad quality control, wrong cooling processes and so on. Buried Know

And when you have luck and get a silent reissue, I bet, it sounds worse than the
original because the remaster was done mediocre (Today money counts, not
perfection).
Second Hand Records from the former years can be in top optical condition, no
scratches and when you play it, you will have noise. This is mainly based on the
fact, that a previous owner used a wrong aligned cart/Arm or too much VTF.
Then the grooves are damaged. Best you can do, throw it away (I do it). Short
pain, but then it is done.
When a record is not silent after 2 cleaning processes with a point nozzle and a
cleaning fluid, then there are normally grooves damaged or the vinyl has
problems, years ago it was very common to use alcohol in cleaning fluids, when
done wrong, the groove side walls got dry, inflexible and the only chance to
enjoy them is a cart with a round needle :-)
Or you go the way with short pain....500 top records are better than 3000 noisy
ones. Life is too short for that
