Trial Number 0

Trial Purpose:

To determine a cleaning method

Date Run:


Experiment Procedure:

The purpose of this trial is to determine a cleaning method that would be appropriate for Modeform. For the First part of the trial, a contaminated hook was brought to AA Environmental in Woburn MA. to determine the effectiveness of Sodium Bicarbonate blasting. This process proved to be very effective. All of the built up coatings were removed from the hook in about 30 seconds.
The next test was to see if there was a drop-in chemical substitute for Methylene Chloride that would be just as effective. The coated end of eight different hooks were immersed in 500 ml concentrated solutions of eight different chemicals.

CONTAMINANTS: Coatings/Urethanes
CONTAMINATING PROCESS USED: As recieved from Manufacturer of Furniture.

Trial Results:

The only chemistries that showed potential was the CSA Biosafe and the General Chemical Aquaclean 5784.  Both of these chemistries pulled of two to three layers of coatings, but did not perform as well as necessary.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.


For this cleaning application, it does not seem that a non-regulated solvent will be effective alternative for Manufacturer of Furniture's current cleaning procedure.  On the other side the sodium bicarbonate blasting service by AA Environmental is definitely effective.
