Three sets of three steel coupons were weighed and immersed into three distinct beakers containing Aquavantage 1400 GD, Liquinox, and SC-1000 respectively. Heated ultrasonics was conducted at 122-125°F for 15 minutes. Coupons were submerged in three distinct beakers containing deionized water as a rinse step for 5 minutes. Coupons were dried with an air gun for 10 minutes. Effectiveness of cleaning was observed gravimetrically after the drying step.
After 15 minutes of heated ultrasonics and subsequent post-treatment, coupons treated with Aquavantage 1400 GD and Liquinox lost a thousandth of a gram, while coupons cleaned with SC-1000 lost a hundredth of a gram.
Based on gravimetric analysis, Liquinox on average had the least amount of weight lost for the steel coupons. Coupons cleaned with both Liquniox and Aquavantage 1400 GD lost a thousandth of a gram. Coupons cleaned with SC-1000 lost a hundredth of a gram. The next step would be to continue testing with the vanishing oil contaminant provided by the company.
