Trial Number 164

Trial Purpose:

Laboratory evaluations of alternative cleaning products

Date Run:


Experiment Procedure:

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

Cleaning: Media Blast with Baking Soda in machine from BSC Co Inc, Blasted each coupon 20-30 seconds under pressure of 80-100 psi
Rinsing: 1/2 minute with tap water, manual, at 120 F
Drying: Heat gun at 500 F
Contaminant: Aroset PS 8078, Ashland Chemical

Success Rating:

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


Media Blasting with baking soda is very ineffective on tacky adhesive. Used coupons 20 - 25 from trial 161. Did media blasting on 23 - 25 for standard time of 10 - 20 seconds with poor results. Media blasted coupons 20 - 22 for much longer time frame may help, but not likely.
