THE PRINCIPLE
Ultrasonic cleaning works by agi-
tating the cleaning liquid with high
frequency acoustic pressure waves.
This creates a large number of
microscopic vacuum bubbles in the
liquid, a phenomenon called cav-
itation. With every pressure wave,
countless small vacuum bubbles
are created and collapsed, releas-
ing heat and water jets towards the
record. This action will safely loosen
and remove dirt and contaminants
from the record.

CLEANING RECORDS
Ultrasonic cleaning as used in
Degritter removes contaminants
from records layer by layer. The
cleaning is equally strong on the
top of the groove and inside the
groove.
However, when records are covered
with a thick layer of gunk, it can
take ultrasonic cleaning some time
before the deepest layer of dirt is
reached. We therefore recommend
to first wipe heavy surface dirt

away with a microfibre cloth. This
will speed up the cleaning process
and will give better results faster.
NOTE
Wiping the record with a microfiber
cloth wet in record cleaning fluid or
isopropyl alcohol will speed up the
cleaning process when cleaning
extremely dirty records.
