The best way to protect & maintain your fretted instrument

Putting polish over polish multiple times is not a good idea without doing proper cleaning before putting more polish on.  You end up with a buildup of product (polish & grime) and most often a streaky mess... Most other "polishes" do this, especially products containing oils, waxes, and other greasy additives.  A polish may remove scratches and make things more shiny and pretty, however, you must first clean with Black Diamond Strings CLEAN IT! Pre Polish Cleaner to eliminate months of buildup of grime and oils that may harm your instrument.  


Black Diamond Strings CLEAN IT! Pre Polish Cleaner does add a surface protectant that helps keep High Gloss finishes looking their best and minimize new marring without the liability of added abrasives.

Black Diamond Strings CLEAN IT! Pre Polish Cleaner doesn't change the sheen or original look/patina.  It works great on flat, satin, and high gloss sheens. Consider it a maintenance/detail product that cleans and leaves a soft feel that doesn't build up after multiple uses. 

Fine instrument finishes such as nitrocellulose, urethanes, and polyesters should never be dry wiped.  Black Diamond Strings CLEAN IT! Pre Polish Cleaner sprayed into a cloth or onto the finish provides the lubrication needed to prevent scratching from a dry cloth. It cleans to the original finish and adds protection, reducing static cling and dust while removing skin oils (fingerprints/smudging).  The dirt and grime, especially combined with skin oils/sweat, are what degrade finishes over the long haul. 

Black Diamond Strings CLEAN IT! Pre Polish Cleaner  is a clean, simple, effective product.  It's not a rejuvenator or miracle in a bottle.  It's designed to keep an instrument looking as original as possible.
