To identify possible cleaning product for PVC removal.
Date Run:
11/06/2008
Experiment Procedure:
Ten products were selected from the lab's on-line database, www.cleanersolutions.org, based on client supplied information and past testing results. Six products were diluted to recommended concentrations using DI water. The remaining four products were used at full strength. The supplied PVC tubing was cut into 2-3 inch pieces and immersed into each solution at room temperature. Observations were made at 20 minute intervals for the first hour, than at 2 hours and 4 hours total immersion time.
Trial Results:
Successful products were determined by touching/squeezing the tubing after each interval. If there was any surface change, the product was considered to be successful. Observations for each product at each interval are listed below.
