Trial Report



Trial Number 369

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 01/30/06

Experiment Procedure:
Initially four cleaners were selected for removing candle wax and carbon deposits from glass jars. Each product was used at a diluted concentration.

Prior to the addition of any cleaning product, the glass jars were soaked for 5 minutes using tap water at 120 F to remove excess wax in the bottom of the jar. The inside of each jar was wiped to ensure approximately the same level of contamination.

Following bulk removal of wax, each cleaning product was poured into a jar and allowed to soak at 120 F for another 5 minutes. Then the inside of the jar was wiped with a paper towel to remove the contaminants. This process was done while still filled with warm cleaning product. Each jar was cleaned for about 5 minutes. At the end of cleaning, the jars were photographed and compared to the other products.

Trial Results
Only one of the four initial products had difficulty removing most of the wax and carbon deposits within the five minute wiping. After photographing
this jar, another product was selected and emptied into the jar and cleaned in the same manner as the other products. The table below lists the
observations and ranking for each of the five products.

Cleaner            Observation                 Ranking
DFC 23             Wax residue still on jar       4
                   most of the carbon deposits
                   were gone
H2O2               Very clean                     1
DFC 30             Almost as clean as H2O2        2
                   Some wax still remaining
Bi-O-Klean Glass   Similar to DFC 30
                   Some carbon deposit remaining  2

Cogent Degreaser   Worked as well as H2O2         ~1
                   Did have less to remove at 
                   start


Success Rating
Lab evaluation based on vendor data.

Conclusion
Four of the five products worked well at removing the wax and carbon deposits from glass jars using manual wiping.
