The Go-To Fluid for Extremely Dirty Vinyl LPs: Mobile Fidelity Sound Lab Super Deep Cleaner Also Acts as a Pre-Cleaner, Removes Pressing Debris and Mold Compound from New LPs Mobile Fidelity Sound Lab Super Deep Cleaner is made to clean very soiled LPs and also functions as a pre-cleaner for extra dirty records. Super Deep Cleaner can even be used for removing pressing debris and "mold release compound" from sealed LPs. It's more powerful than Mobile Fidelity's Super Record Wash and should be used as the first step in your cleaning process . As always, Mobile Fidelity Sound Lab Super Deep Cleaner is made with an exclusive quad-distilled, hyper-pure water base with a mild detergent that leaves no residue and does not damage the surface of your records. While Super Deep Cleaner may not spread out over your LP surface like other record-cleaning solutions, its high-surface-tension water composition is exactly what you want in a solution . Why? The high-surface-tension water not only lifts the debris from the record, it actually holds the debris so that it can be safely and effectively vacuumed away from your record. By contrast, low-surface-tension solutions allow the debris to flow back into the record groove, leaving behind debris, where it can leave a sonic signature and mar performance.
