Music lover, record collector, audiophile, perfectionist. How do you describe yourself and your passion for music enjoyed on
phonograph records? Today, it is widely accepted that properly cared for records sound better and last longer. How do you build an LP library for a lifetime
of musical enjoyment?
For over 2 decades, record cleaning machines (RCM) have been recognized as the most effective way to maintain an LP library.
Wet cleaning is critical and the complete removal of the contaminants from the record without groove damage and residual sonic signature is essential.
Commercially available RCMs do an adequate job of rotating and vacuuming dry the wet cleaned record but what fluid and application method are best?
Brian Weitzel, a chemist and LP enthusiast in the Pacific Northwest, has developed what he considers a very safe, non-invasive, yet effective method of
cleaning records to audiophile standards. His approach depends on using a wet-wash/vacuum dry machine...and his own proprietary fluids: Record Research Labs
Vinyl Wash for “everyday” use and Record Research Labs Deep Cleaner for hardcases.
To achieve the proper base for RRL fluids, Weitzel
designed and built a special copper distillery, producing distilled, quadruple deionized water. Distilled water as a base alone still contains many trace
minerals which can be positively or negatively charged and attach themselves to the vinyl. Deionized water reduces the level of trace minerals in the reacted
water, greatly reducing the amount of mineral contaminates on the record itself. Chemical labs have for years used deionized water in their work. Lab grade
water is single stage deionized water, RRL is quadruple deionized. These added stages provide us a base that is
The active portion of the solution is a low level surfactant that is effective at lowering the surface tension, penetrating and
lifting grease. This surfactant is both alcohol and phosphate free. Alcohol permeates the vinyl surface and “leaches” out essential oils from the
jagged groove walls. Vinyl life expectancy may be reduced by alcohol based cleaners due to the heat created by the stylus in the groove without necessary
lubrication. Phosphates can bond to the surface of the record and are environmentally damaging. Trisodium EDTA is added to the surfactant as a preservative,
greatly reducing bacterial growth with no sonic signature. Carboglycinates are added as a vinyl lubricant, again chosen for its lack of sonic signature. Both
compounds are vinyl and environmentally friendly.
Weitzel, incidentally, is no fan of the nylon-bristled brushes most cleaning machines are used
with, saying they're too coarse, too stiff, and too prone to damaging grooves. He believes it's better to use a gentle, non-aggressive brush to apply and
spread the fluid, and to simply let the cleaner do its job chemically. To this end, Weitzel recommends using only a carbon-fiber brush with his
fluid…this whole approach takes a little getting used to, as you can't really scrub with these things—and besides, neither the fluid nor these
sorts of brushes seem keen on getting the entire record surface wet. (Some manufacturers add “fotoflo” as a wetting agent to help spread their
fluids, but Weitzel believes it can leave an unpleasant residue behind.)
Photo-Flo has been used in other cleaning formulas as a “wetting
agent” in an attempt to break down valence bonds, lowering surface tension. Unfortunately, Photo-Flo leaves behinds residue that is not only heard, but
can be seen as well. This wetting agent attaches itself to the cleaning agent, greatly hampering its effectiveness. If the cleaning agent contains any
phosphates or trace minerals, they stay behind on the record surface. Quadruple stage deionized water and low level surfactants are the correct way to reduce
surface tension when cleaning records. It should be noted that lowering the surface tension of previously bound contaminates, these contaminates become
suspended in the fluid and are vacuumed away. No volatile organic compounds or ozone depleting substance are used making RRL fluids a true “green” cleaner.
