Since CCleaner has gone to personal use only I'm looking for a free basic cleaner software that I can use to clean out production/commercial machines. As I have done with CCleaner, I promote the paid products to my clients as they tend to include advanced features/automations/etc. But at least on a base level, I encourage a free basic cleaner, The free products with paid versions tend to be updated so I am looking to alternative products and naturally want to be in line with licenses. I've looked through the attached EULA but it doesn't plainly state if the free products can be used on commercial machines or not. Thank you in advance for any responses.
