Suggestions for an effective record cleaning kit??

I have just purchased a new Rega turntable and have gotten back into analog. I need some advice about record cleaning accessories. I currently use a "spray on" cleaner called "Premier" which seem OK, but it is hard to judge if it is really doing the job. Several years ago, I bought a basic "Needle Doctor" record cleaning machine that in my opinion did very little to improve the sound of my LP's.. I have generally taken good care of my limited collection, but some are just old with varying degrees of pops, clicks and noise. I still have a copy of Cat Stevens "Tea for The Tillerman" purchased in 1972---it actually sounds decent. Thanks, Jim
