The Discwasher's D4+ Vinyl Cleaning Solution is for use with the Discwasher Vinyl cleaning System (D4 kit). Used with the D4+ cleaning pad, the D4+ Vinyl Cleaning Solution works to safely and effectively cleans records without reducing their dynamics or fidelity. The specially formulated solution lifts contaminants from -and suspends them above- the record surface for removal by the soft, non-abrasive, unidirectional fibers of the D4+ pad. Together, the D4+ solution and pad eliminate airborne contaminants, particulate matter, and oily fingerprint smudges that work their way into the grooves. These contaminants compromise the audio and shorten the record's effective plying life. The D4+ Solution cleans and protects without deposit residue or extracting crucial vinyl stabilizers. Regular use of the D4+ Vinyl Cleaning System can help keep your records sounding their very best for many years of enjoyment.
