Trial #0
To test the compatibility of the chemical makeup of the Titan product with the substrates of fiberglass/polymer, chrome, and ceramic in comparison with a comparable baseline product.
Basic ASTM F483 Compatibility Testing Procedure:
Three coupons of each substrate were used per cleaner, for a total of 18 coupons. Each coupon was weighed to the nearest 0.1mg and had that initial weight recorded. The coupons were then immersed in their respective cleaner at room temperature for 24 hours. After 24 hours, each coupon was removed from the cleaner and rinsed thoroughly under hot tap water at 120-140F. Following the tap water rinse, each coupon was rinsed with room temperature DI water followed by a room temperature Acetone rinse. The coupons were then allowed to air dry for a few hours. After the coupons had fully air dried, they were visually analyzed as follows-
a. Discoloration and Dulling
b. Etching
c. Presence of accretions and relative amounts
d. Pitting
e. Presence of selective or localized attack
The coupons were then placed back into immersion with their respective cleaners for a subsequent 144 hours. After 144 hours, the coupons were removed and rinsed following the same rinsing steps previously performed. After fully air drying, the coupons were then visually analyzed repeating the same visual categories. Each coupon was weighed to the nearest 0.1 mg, and the weight loss or gain of each coupon was recorded.

Significant discoloration was observed following the first 24 hour testing period on the chrome coupons that were immersed in the Titan Home Cleaning Solution (formulation 1). The discoloration was first observed at the 1 hour mark of immersion. The discoloration increased as immersion continued. This discoloration is described as black spotting. Noticeable dulling was observed following the full 168 hour testing period on the chrome coupons immersed in the Zep Cleaner.

Although the chrome coupons immersed in the Zep cleaner show a greater visual ranking of observed etching, based on the gravimetric results it can be seen that the chrome coupons immersed in the Titan Cleaning Solution experienced greater etching based on a greater loss of weight over the course of the testing period. It is likely that the etching was not as visually noticeable on these coupons due to the dark black discoloration. The etching of the Titan Cleaning Solution (formulation 1) would not have begun until the 1 hour mark at which the discoloration was first noticed.
All cleaners are highly compatible with plastic and ceramic. Both the Zep Foaming Shower, Tub and Tile Cleaner and the Titan Home Cleaning Solution (formulation 1) caused some level of damage to chrome coupons, with this damage being more significant for the Titan Home Cleaning Solution Bathroom Cleaner (formulation 1) compared to the Zep Foaming Shower, Tub and Tile Cleaner however, the discoloration was not noticed until the 1 hour mark of testing. As the use of this product would not require more than 3-5 minutes of contact time, this should not pose an issue. The Titan Home Solutions (formulation 2) was completely compatible with all substrates.
