Ultrasonic cleaning as used in Degritter removes contaminants
from records layer by layer. The cleaning occurs equally strongly on
the top of the groove and in the groove.
However, when records are covered with a thick layer of gunk, it
can take ultrasonic cleaning some time before the deepest 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.

Ultrasonic cleaning has a unique ability to remove dirt that is not easily
accessible using other traditional means. Ultrasonic cleaners are used to
clean many different types of objects, including jewelry, optical parts,
dental and surgical instruments and electronic equipment.
The smallest features in a vinyl record groove are the size of a few micro-
meters. The bristles on a typical vinyl cleaning brush are unable to reach
the bottom of the groove as they are too large in size.

Ultrasonic cleaning works by agitating the cleaning medium with high
frequency acoustic pressure waves. This creates a large number of
microscopic vacuum bubbles in the cleaning medium, a phenomenon
called cavitation. With every pressure wave, countless small vacuum
bubbles are created and collapsed, releasing heat and water jets towards
the record. This action will safely loosen and remove dirt and contami-
nants from the record.
