Trial Number 375

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. 

Six products were selected for testing based on an aerosol formulation for brake cleaning. Another product was selected but tested using a manual pumping delivery. The products were used at full strength in spray cans as delivered by the vendors. Products were used at room temperature. Seven 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. One coupon was cleaned in for 30 seconds using the spray can. Coupons were weighed and 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
BioBrake 0.2126 0.0273 87.16
Mirachem 500 A 0.1413 0.0224 84.15

Heavy Duty Cleaner-Degreaser 0.5537 0.0893 83.87
Micro X 0.3644 0.0143 96.08
Non-chlorinated Brake Cleaner 0.8154 0.0322 96.05
SL 100 0.6062 0.0935 84.58

Success Rating:

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


All seven aerosol products showed good cleaning abilities in the preliminary testing phase and all will be evaluated further.
