Have good results using Mobile Fidelity brush as applicator and scrubbing cleaner for one offs......
Replacement pads can be purchased and I have yet to put mine on..... as I'm still getting good results with the existing brush pad.
I think that one thing is forgotten here:
On a RCM like the Okki Nokki, the fluid is placed on the record, where after the fluid is spread equaly over the record area with the (supplied) brush.
By the looking at the MoFi brush pad, I can only conclude that this will never be sufficiant to do this, in fact it will only collect the fluid in front of the brush, without spreading it over the record, most likely pushing most of the fluid over the record edge.
The MoFi pad is in my opinion more to "scrub" the already wet record, or to moisten the pad before putting it on the record surface.
I have done some experimenting on this, including a MoFi like pad, only with a curved bottom area. I can only say that at this very moment I'm using the Okki Nokki brush again to give me the best results.
Sometimes the surface of a LP is a little "greasy" causing the fluid not willing to spread equaly. In that case I take the curved pad, put it on the record very light, only to moisten the pad surface with the fluid that was already present on the record from the first try, and then gently press it on the record. After that I can use the Okki Nokki brush again.
Vinyl, tubes and tapes... how lucky can you be
