Trial Number 8

Trial Purpose:

To evaluate bio-based floor strippers on plastic composite tiles

Date Run:

01/18/2005

Experiment Procedure:

Three products were used at 100% v/v concentration of selected bio-based cleaners. Nine pre-weighed ceramic tiles were coated with Johnson Wax Professional Show Place floor finish (40861-29-8, 78-51-3, 34590-94-8, 111-90-0) using a hand held swab. The finish was dried using a hand held heat gun for two minutes at ~300 F. Once the finish/coupon had cooled, three more coats were applied following the same procedure. Coupons were reweighed to determine the amount of finish that was applied.

The coupons were sprayed with a cleaning product. The formulation was allowed to sit on the finish surface for 10 minutes. Three coated coupons were firmly held on an abrasive machine for manual wiping Abrasive pad (QEP Grout Clean Up Kit Coarse) was held firmly on the abrasive machine in order to imitate the working properties of the floor stripping machine. The cleaning lasted for 5 minutes at an interval of 1 minute with spraying of the cleaning agent on the pad as well as on the tiles in between. At the end

Trial Results:

The table below lists the amount of finish applied, remaining and the percent effectiveness for each coupon cleaned.

A follow up test, usually based on company input.

Conclusion:

The botanical garden seems to have worked effectively well in this experiment with the removal efficiency of about 87%.  From the qualitative assessment the botanical garden cleaner seems to have performed better (average removal efficiency of 91%) than the other bio-based cleaners (28% and 24% for Bio-T-Max and SC-Actisolv, respectively).
