Mine arrived and I've cleaned around a dozen records with it. I am using it without any electric spinner. Every five minutes I rotate the record 120 degrees. It does visibly damage the label, plus it is annoying to keep rotating it. So I do want to invest in some automated rotation system.
As for the cleaning, I am not sure how great it is compared to sink method. I am using tap water with some dish detergent. Then I rinse off with distilled water from a spray bottle. Perhaps using tap water is a big no-no?
I think the records sound a little better, but pops and ticks are still there. I am guessing most poorly kept records sound bad because of scratches and damage from needles. Dirt is only a fraction of the problem.. Anyways, I am new to record cleaning. Even though I have been collecting for 20 years , I always stick to NM quality used vinyl..
Besides vinyl I used it to clean my eye glasses. It did a great job with that. I've tried it with some tarnished silver bowls, but it did not do anything for those. Perhaps that needs some special cleaning solution..
