Hi,
Thanks for your detailed post. I have always added a few drops of dishwasher rinse aid with the iso-propyl and water so maybe the Ilfotol is better, I will certainly try it and also add it to the water when rinsing.

Hi Shakey, I use the Knosti manual cleaner as well and experienced the same issue with gunk on my stylus. I also have tried weaker mixtures and never allow the record to dry fully before rinsing them. I would be glad of any solutions. Cheers
