Reducing Background Noise On Records

I spray the fluid on then immediately use the brush while rotating the record 5 times.  I apply moderate pressure on dirtier records.  Then I spray on distilled water and use a clean brush again rotating the record 5 times.  I do this twice. 

FYI, my cleaning fluid consists of 75% isopropyl alcohol 91% pure) and 25% distilled water, with a few drops of Fawn dishwasher detergent and Rinse Away rinsing agent. 

 Sorry, Dawn dishwasher detergent. 

I think part of the answer to your question hinges on your definition of  "noise", but here is an additional 2 cents...

I got my ultrasonic record cleaner today and it is a bit of a revelation.  The majority of my records are in good to excellent shape and had been cleaned with a Nitty Gritty at least once, stored in rice paper sleeves, non smoking household etc.

I've just cleaned and played a few older, well-played records and the difference is pretty startling.  It's just all around better - quieter, more detailed, etc.

I opted for one of the cheaper solutions

I'm sold on ultrasonic cleaning and will be busy cleaning records for the foreseeable future. The other great thing about this new cleaner, is that I'm now inspired to go used record shopping knowing that I have a really good way to clean up the records.

PS - My front end is of reasonable quality, but not crazy
Rega P25 with some slight mods and a Shelter 901.

The Ortofon 2M Blue is the weak spot for sure. It has elliptical stylus and high 5.5 mV output.
Flat mids, dull highs and gloomy base from what I experienced. If you want to stick with MM- try good 1000 or 2000 series GoldRing. You will see most of problems will go away.
 Ultimately go to MC.
If need any cartridges- I can help for sure.

If you want to destroy your MC cartridge just keep following geofkait's advice.

That’s just great! Another poster from the water turns to steam and destroys the cartridge school. First, water is a coolant. There would be less heat not more. Second, by the time the water turns to steam, assuming it did, which it almost certainly doesn’t, the cartridge would have already passed and steam would not touch the cartridge, the steam would go into the open air. The cartridge would be untouched by the steam. Your theory is all wet. 🤡

@vpi I hate to judge before all the facts are in but it appears YOU not water are the biggest threat to your cartridge. 

”Unfortunately, I ran my Clavis with the case removed and while dusting my VPI I hooked a shirtsleeve on the cantilever and snapped it off. My clavis is currently with Soundsmith. I only hope the rebuilt Clavis retains the wonders of the original.”

 No, I don't let the liquid sit.  I do let the record turn five times though before I vacuum it up. And I repeat that procedure twice with distilled water.

 I've been watching a bunch of videos on ultrasonic cleaning and I think I'm going to try a DYI version of that.
