Trial Number 163

Trial Purpose:

Laboratory evaluations of alternative cleaning products

Date Run:

01/31/2002

Experiment Procedure:

Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning. 

Cleaning: 1. Using soda blasting unit with baking soda as the medium.
2. Using snow gun with carbon dioxide as the medium.
Rinsing: Tap water rise at 120 F.
Drying: Air drying.
Contaminant: Paint - Nybco- designer colors -satin finish

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

Soda blasting worked very well but snow gun did not work at all.
