To evaluate successful products on second supplied contaminant
Date Run:
10/09/2008
Experiment Procedure:
The top seven products based on past testing results were again diluted to 5% using DI water in 400 ml beakers. All seven products were heated to 130 F on a hot plate.
Peweighed aluminum coupons were coated with the Everite Electrolite Salt mixture using a handheld swab. The contaminant was allowed to dry for about 10 minutes. Once dry, the coupons were weighed a second time to determine the amount of oil applied.
Three coupons were immersed into each solution and cleaned for 5 minutes using stir-bar agitation. Rinsing was performed for 15 seconds using tap water heated to 120 F and followed by 30 seconds of air blow off with dry compressed air at room temperature. Final weights were recorded, and efficiencies were calculated for each coupon cleaned.
Trial Results:
All seven products were effective at removing the salt mixture from the aluminum coupons within 5 minutes of immersion cleaning. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
