I have an old partial bottle of LAST System Formula 1, extra-strength record cleaner. Is this the same as the power cleaner and do you suppose that what I have is still safe to use? It seems OK to me. Thanks! -M.S.
Dear Mr. S,
System Formula 1 extra strength record cleaner is not exactly the same chemical formula as Power Cleaner, but it has the same function. It is still safe to use, and fully effective. We no longer make System Formula 1, as the Power Cleaner offers the same capability. Thanks for your question. Enjoy your music!
