Hello Chocolate,

The word "clean" can be used as an adjective or as a verb. So you can say:

Her house is always beautiful and clean (adjective).

or

I've just cleaned my teeth (verb).
I spent the morning cleaning the house (verb).

"Clean up" is only used as a verb; this time of verb is known as a phrasal verb. Clean up means to clean something completely and thoroughly. So:

I want you to clean up this mess immediately. i.e. the mess will disappear.

"Clean up" can also be used to talk about crime.

The mayor's objective for the coming year is to clean up the city. i.e. get rid of crime.

Best wishes

Lucy
