Cleaning Methods

There are two methods of cleaning - direct and indirect. Each has advantages and
disadvantages. When in doubt, run test samples using both methods to decide which
one produces the best results for you.
Direct method
• Items in perforated insert tray
• Item suspended
How it works:
Fill the tank with warm water and a cleaning solution.
Place the items to be cleaned in a perforated tray and lower them into the tank. You
can also suspend items on a wire and then immerse them in the solution.
The advantages of this method are the simplicity of operation and cleaning
effectiveness.
Indirect method
Items laid randomly in solid insert tray
Items placed in beakers
How it works:
• Fill the tank with warm water and a cleaning solution.
• Pour your solution medium into one or more beakers or into a solid insert tray.
• Place the beakers in a beaker positioning cover or a solid insert tray to fit your
cleaner. Beakers should not touch the tank's bottom.
The advantages of this method are:
Removed soil stays in the beaker or tray so you can easily examine, filter or discard
it.
You can use one or more solutions at the same time.
o Two completely different cleaning solutions.
o One beaker or tray with a cleaning solution and one with a rinse solution.
Cleaning solution in your tank needs to be changed less often.
