Nothing wrong with that. Cleaning comes down to how good a job you do, all the fancy equipment just makes it easier, and easier to screw up. I once spent a good couple of hours cleaning a bunch of records, and I had to go back and redo every one because the "lips" on my vacumn were contaminated. I learned. I generally also clean my records only once, clean records tend to stay clean records, especailly with the aq brush. And new sleeves, of coarse.
