Seven sets of three pre-weighted titanium coupons were soiled with Swisscut Otho NF-X10 using a cotton swab. Each set of coupons were immersed into an unheated cleaner (Dowanol PnBGE, Soy Clear 1500, Metalnox 6386, Dimethyl glutarate, Liquinox, OzzyJuice 3, and SC Aircraft & Metal Cleaner) for 15 minutes, and visual observations were documented every five minutes. After 15 minutes, final weights were measured and efficiency was calculated for each coupon cleaned.

Table 2: Visual Observations

Cleaner 5 minutes 10 minutes 15 minutes
Dowanol PnBGE

- cleaner is clear

-soil is highly viscous

- some soil remained on coupon and settled to bottom

-no change in cleaner

-visually observed that 50% of the soil remained on coupons, and the other 50% settled to bottom

-about half of soil remained in bottom of cleaner

-about half of soil remained on coupons
Soy Clear 1500

- cleaner is clear

-soil is highly viscous

- some soil remained on coupon and settled to bottom

-no change in cleaner

-visually observed that 50% of the soil remained on coupons, and the other 50% settled to bottom

-about half of soil remained in bottom of cleaner

-about half of soil remained on coupons

 

 
Metalnox 6386

- cleaner is clear

-soil is highly viscous

- some soil remained on coupon and settled to bottom

-no change in cleaner

-visually observed that 50% of the soil remained on coupons, and the other 50% settled to bottom

-about half of soil remained in bottom of cleaner

-about half of soil remained on coupons
Dimethyl glutarate

- cleaner is clear

-soil is highly viscous

- some soil remained on coupon and settled to bottom

-no change in cleaner

-visually observed that 50% of the soil remained on coupons, and the other 50% settled to bottom

-about half of soil remained in bottom of cleaner

-about half of soil remained on coupons
Liquinox

- cleaner is clear with bubbles

- soil is highly viscous

- some soil remained on coupon and settled to bottom

-no change in cleaner

-visually observed that 50% of the soil remained on coupons, and the other 50% settled to bottom

-about half of soil remained in bottom of cleaner

-about half of soil remained on coupons
Ozzy Juice 3

- cleaner is cloudy

- soil is highly viscous

- some soil remained on coupon and settled to bottom

-no change in cleaner

-visually observed that 50% of the soil remained on coupons, and the other 50% settled to bottom

-about half of soil remained in bottom of cleaner

-about half of soil remained on coupons
SC Aircraft & Metal Cleaner

- cleaner is an orangeish color

- soil is highly viscous

- some soil remained on coupon and settled to bottom

-no change in cleaner

-visually observed that majority of the soil remained on coupons, and the remaining soil settled to bottom

-minimal soil remained in beaker

-majority of the soil remained on coupons

Metalnox 6386, Dowanol PnBGE, and Liquinox were the most effective at removing J2 soil from titanium substrates using unheated immersion. The next step will be to evaluate which cleaners can be heated and perform a heated immersion using the same time and concentration.
