Trial Number 372

Trial Purpose:

Laboratory evaluations of alternative aerosol cleaning products

Date Run:


Experiment Procedure:

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

Two products were selected for testing based on equipment compatibility and soil removal. The two products were used at full strength in 250 ml beakers. Products were used at room temperature. Six preweighed aluminum coupons were coated with a collection of brake/engine soil collected from an automobile shop. The coupons were allowed to sit for several days before a second weight was recorded. Three coupons were cleaned in each solution for 5 minutes using minimal agitation from a magnetic stir bar. Coupons were then rinsed in tap water for 15 seconds and dried using air blow off at room temperature for 30 seconds. Following drying, final weights were recorded and cleaning efficiencies were calculated.

Trial Results:

The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Cleaner Initial wt Final wt % Removed
Citrus Soil 1 0.2188 0.0541 75.27
  0.1777 0.0301 83.06
  0.1853 0.0253 86.35
Canola Gold CE 110 0.3455 0.244 29.38
  0.3291 0.2677 18.66
  0.2502 0.247 1.28

Success Rating:

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


The Citrus Soy has been the most successful product tested so far under the room temperature immersion cleaning.
