F10 is a disinfectant like Chlorhexadine. There is SC which is the disinfectant you can just let dry and is safe for the reptiles. Then there is SCXD which is a disinfectant plus a cleaner. You need to rinse the SCXD stuff off. Here's a link to all the cleaners. http://www.reptilebasics.com/cleaning-products
