Best way to clean vinyl ???

Depends on your budget. There are some excellent record cleaning machines by VPI ($1000) and Nitty Gritty ($450 to $650). If you want something inexpensive like a manual pad with a cleaning solutions, there is a good cleaning system made by a company called LAST ($20 to $50). For something simple and cheap there is also the Discwasher system. Some folks also swear by soap and warm water.

Shy of the old Keith Monks machine, the VPI followed by the Nitty Gritty. Washing records in luke warm water and soap has worked for me...but...you need to find a liquid soap with no perfumes or oils in it...and one that will rinse of totally..(soft water is a must), and you must have a lint free towel...such as used for fine crystal/wine glasses.. check Williams-Sonoma...usually cotton or cotton/linen blend...no synthetics....a big..also..is that you must also keep from getting the labels wet. All said and done,..a Discwasher system works well for most people.. One of the top end Grado's is a good match for the Rega.
