Trial Number 3

Trial Purpose:

To test the efficiency of ServeCo All Purpose Cleaner against Seventh Generation All Purpose Cleaner at removing Hucker's Soil from various substrates.

Date Run:

01/28/2025

Experiment Procedure:

Eighteen pre-weighed coupons, three per substrate per cleaner, were contaminated with 0.5 g of Hucker’s soil composed of 44.2% distilled water, 13.5% evaporated milk, 8.8% salted butter, 8.8% stone ground wheat flour, 8.8% egg yolk, 0.9% printer’s ink with boiled linseed oil, 2.7% saline solution, and 3.5% India ink. Coupons dried at room temperature (68°F) for 24 hours before their dirty weights were recorded.

Three coupons of the same substrate were placed in a Single Line Washing Unit (SLW) with a Wypall X60 wipe attached to the cleaning sled. The wipe and coupons were sprayed three times with the cleaner and soaked for 30 seconds. The SLW was then run for 20 cleaning cycles (30 seconds of manual cleaning). Coupons dried overnight at room temperature before final weights were recorded.
