Caustic Soda Method
WARNING: CAUSTIC SODA CAN BURN SKIN AND EYES, IF HANDLED IMPROPERLY . NEVER HANDLE CAUSTIC
SODA WITHOUT USING THE FOLLOWING PERSONAL PROTECTIVE EQUIPMENT (PPE): GLOVES, GOGGLES AND
TONGS . IF CAUSTIC SODA TOUCHES THE SKIN, WASH IT AWAY IMMEDIATELY . IF CAUSTIC SODA TOUCHES THE
EYES, IMMEDIATELY USE AN EYEWASH TREATMENT .
CAUTION: Never operate the unit without water in the cleaning tank . Damage may occur .
CAUTION: Never use boiling water . Damage may occur .
CAUTION: The unit must be positioned on a flat, stable work surface. Do not tip over or move the tank during its
operation. Electrical equipment can become damaged when exposed to water and other fluids.
1 . Fill the tank with 0 .75 liters (0 .79 quarts) of cold water .
WARNING: DO NOT ENGAGE THE ULTRASONIC FEATURE WHILE STIRRING IN THE CAUSTIC SODA . THIS WILL
CAUSE THE SOLUTION TO VAPORIZE .
WARNING: ENSURE THE AREA IS WELL VENTILATED AND DO NOT DIRECTLY INHALE THE VAPOR FROM THE
TANK .
2 . Using scales and a measuring bowl, measure out 200 grams of caustic soda .
3 . Pour the caustic soda into the tank in approximately 40-gram increments, stirring thoroughly after each addition .
NOTE: Stirring is essential to ensure the caustic soda granules do not collect at the bottom of the tank .
4 . Immediately clean the measuring bowl and scales to ensure removal of all caustic soda .
5 . Using plastic tongs and all the recommended personal protection equipment, gently lower the model into the caustic soda solution .
CAUTION: Exercise caution so that none of the solution spills .
6 . Close the lid .
7 . Connect the power supply and press the power button to turn on the tank .
8 . For best results, set the temperature to 60
°C . Use the -5 and +5 buttons to lower or increase the temperature .
WARNING: DO NOT SET THE TEMPERATURE ABOVE 60°C AS THE REACTION BETWEEN THE CAUSTIC
SODA AND THE WATER IS EXOTHERMIC, AND WILL CONTINUE TO ELEVATE THE TEMPERATURE . ACTUAL
TEMPERATURE SHOULD NEVER EXCEED 80°C .
9 . Once the tank has reached 60
°C, use the -5 and +5 buttons to set the timer for 180 minutes .
NOTE: The ultrasonic process will begin as soon as you have set the time .
10 . After 180 minutes, remove your model from the tank using plastic tongs and run it under cold water for 1-2 minutes .
CAUTION: Continue wearing the recommended personal protection equipment when handling the model until the
process has been completed .
NOTE: All support material should have dissolved . Any remaining supports can be crumbled or scraped away with a
blunt knife or rinsed off in the sink .
11 . Empty the caustic solution from the Ultrasonic Support Removal Tank .
NOTE: It is safe to pour it in the sink as caustic soda can be used as a drain cleaner .
