To screen potential alternative cleaning products
Sixteen products were selected from the lab's on-line database of testing results, www.cleanersolutions.org, based on client supplied information and past testing results. All products were used at room temperature and full strength. A 1 milliliter sample of fourteen of the products was applied onto the surface of the part and allowed to sit for about one minute and then was wiped off to determine if there was any affect on the carbon deposit. Observations were recorded on the effectiveness of the solutions.
The last two products utilized media blasting using baking soda and carbon dioxide as the medium. A portion of the ceramic part was cleaned for under 1 minute to determine the potential cleaning of the blasting.
Five of the liquid products showed some to little signs of removing the oxide layer. The other 10 had no effect. The baking soda blasting was the only process that was effective in removing the contaminant. The table lists the observations made for each of the 16 products.

Success Rating:Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Baking soda blasting was the only option found to have definite cleaning of the carbon deposit from the ceramic parts.
