Record Cleaner Okki Nokki

No I have not. Audio Intelligent has a great reputation so I just got it and have been using it. Many like Walker too.
I use step 2, Archivist formula, that contains no alcohol, it can be substituted with another Audio Intelligent solution with alcohol. I understand that the result is the same, I prefer not to use alcohol, just in case.

Thank you for all the feedback. Inna, I will try different fluids, so far I only used the Okki Nokki with the supplied brush. Have you ever tried any home made solution? The typical formula is distilled water+iso propyl alcohol+surfactant (like Ilford Ilfotol).

Yeah, but also what kind of fluid do you use? I am using this machine with excellent results with Audio Intelligent three step system and Disc Doctor brushes for each solution. After applying the fluid 1 - enzyme- and fluid 2 - Archivist Formula - I let it soak for 2-5 minutes before vacuuming. If the record is very dirty - I do double cleaning with step 1 and 2 and let it soak for at least 10 minutes. I rinse with Step 3 - pure water- twice.
I never tried the enclosed Okki Nokki concentrate or the brush.

A record cleaner cannot get rid of pops and ticks unless they are caused by dirt in the grooves. Any scratches or defects will still be there. A cleaner will help keep the dirt from damaging the vinyl further and keep in from gumming up the stylus.
