I have been using L'Art Du Son record cleaning fluid for years on my Loricraft Machine and have been happy with the results. Lately I have noticed that the solution does not last long after mixing and start degrading (see photo) I use glass colored bottles as instructed and mix it with RO/DI water. Has anybody else encountered this issue? Does the solution loose it's effectiveness? I hate to keep re-mixing and wasting a lot of fluid. Maybe I need to look at another product.
