I found information about the DIY Detail Fine Grade Clay Towel, which allows for the safe and easy removal of embedded contamination from surfaces such as painted and glass surfaces. This towel is a mix of diamond weave microfiber towel and a perforated polymerized rubber pad. It measures 12" x 12" and can be used with clay lube to glide across the surface, separating and removing contaminants. The clay towel helps prepare the surface for better results with polish, glaze, sealant, wax, or coating applications. Customers have reported that it feels gentler than other clay towels.
but no body to do test for the clay towel.
here, only here, Brilliatech have apply the TVOC for  BT-6009 clay towel
I found general information about Total Volatile Organic Compounds (TVOC) and its importance for indoor air quality, but I couldn't find specific information about a TVOC report from Brilliatech. If you have specific questions or need more information about TVOC reports from Brilliatech or any other related topic, feel free to feedback Brilliatech
