CLEANING RECORDS
NOTE
Ultrasonic cleaning works by agi-
tating the cleaning liquid with high
frequency acouic 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 di and contaminants
from the record.
Ultrasonic cleaning as used in
Degritter removes contaminants
from records layer by layer. The
cleaning is equally rong 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 deepe layer of di is
reached. We therefore recommend
to fir wipe heavy suace di
away with a microfibre cloth. This
will speed up the cleaning process
and will give better results faer.
Wiping the record with a microfiber
cloth wet in record cleaning fluid or
isopropyl alcohol will speed up the
cleaning process when cleaning
extremely diy records.
