To evaluate selected products on first supplied soil using immersion cleaning
Ten products were selected from the lab's on-line database, www.cleanersolutions.org, based on supplied information from client. Each product was diluted to 5% using DI water in 600 ml glass beakers. Solutions were heated to 130 F on a hot plate.
Thirty preweighed steel coupons were coated with the Castrol Industrial Inc Safety Draw 722X (61788-76-9, 64742-54-7) using a swab. Coupons were weighed a second time to determine the amount of soil added. Three coupons were immersed into each product and cleaned for 5 minutes using minimal stir-bar agitation. Following cleaning, coupons were rinsed for 15 seconds in tap water at 120 F and dried using air blow off for 30 seconds at room temperature. Final weights were recorded and efficiencies were calculated.
No product was very successful using immersion cleaning to remove the Safety Draw fluid. Three of the products had marginal success, removing over a third of the soil in time frame. The table lists the amount of soil added to the coupons, the amount remaining and the efficiency for each coupon cleaned.
|Cleaner||Initial wt||Final wt||% Removed|
|Sea Wash Blue||0.4791||0.3807||20.54|
|Daraclean 282 GF||0.3931||0.3337||15.11|
|Aquavantage 1400 GD||0.5472||0.5084||7.09|
|Polyspray Jet 790 XS||0.4099||0.2508||38.81|
|BG Solv 717||0.4779||0.3699||22.60|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
The three products that were partially successful will be evaluated using ultrasonic cleaning. Additional products will be selected from the lab's inventory as well.
