Is it possible to clean your MacBook Air cache from the system not safari I searched this and there was a web page with software clean my Mac but is this safe to use ?
Yes, I read that in your original post. There are quite a few cache locations in macOS. For example, there are the main caches: ~/Library/Caches and the /System/Library/Caches. There are others, however.
So, can you be more specific? What is it you hope to achieve by deleting a cache?

Free OnyX software is much more reputable than clean my mac. It cleans bunch of various caches, you'll find the options under "Cleaning" tab in the software.
