“NEW” Tesch POWER BRASS Cleaner
Before and After Tesch POWER BRASS and CLASSIC BRASS Cleaners.
"One minute pre-dip in Tesch POWER BRASS, rinse with water, and immerse into ultrasonic
(or straight dip) with Tesch CLASSIC BRASS solution for three minutes. Repeat process if
scale remains. I have found Tesch brass & metal cleaners to be far more effective and safer to
use than any other product." Dana Hofer Brass Repair, Inc. Des Plaines, Illinois
Tesch Chemical Company
has a long standing reputation within the Band Instrument Repair industry. For more than 15
years, repair shops across the U.S. and Canada have used CLASSIC BRASS Cleaner. Satisfied
with the cleaning results of this gentle pH cleaner, technicians asked Tesch to formulate a
companion product to CLASSIC BRASS; a more powerful acid cleaner to replace muriatic and
similar harsh acids still used to clean slides, valves, etc. They wanted an acid cleaner that would
effectively and quickly remove heavy scale with less chance of harm to metal and protective
surfaces.
Tesch listened, and formulated…
