FYI, all Optimum chemicals are produced in our facility in Memphis. Other, non chemical products like pads, towels, Zentool, and accessories are manufactured to our specs by companies that specialize in those areas. Dr G is always sampling/testing new technologies and has other experts like Yvan, Dann, Joel, etc, looking for unique or groundbreaking products. Optimum is careful about adding lines and sometimes the word gets out before we're ready to introduce products (thank you for your patience), but we get it done. And sometimes the idea is excellent but the technology is not quite there (like clay towels, bed liners, etc) and we have to regroup. Thanks for the inside info, Mutant!
