Neither the lab nor end users can delete machines from LubeWear.com for quality purposes. They are permanently created and can only be edited. However, you can edit details by visiting https://learnoilanalysis.com/faq/correct-a-machine-serial-make-and-model-information/ this help guide to change the machine to what you want the details to be. If something is completely wrong we recommend creating a job site that is e.g. “UnusedDelete” and use the https://learnoilanalysis.com/faq/how-do-i-move-a-machine-from-one-job-site-to-another tutorial on how to move all the problem machines to that serial. Indeed if no samples have been created on those machines you can actually rename them completely and use them for other machines using the first tutorial.
