Could you please tell me an easier way to clean my mack book pro model 13

Thank you! In addition to the cleaning info in the link, most of what is on my keyboard is dust. I use non-static pastry brushes (wooden handles; natural, not synthetic, bristles) to clean between the keys of all our Macs, especialy the boards with flat keys like on notebooks and the newer "Magic" keyboards.

Help us help you: Clean what? the screen? The outside of the case? The hard drive contents?

We are not good at guessing.

Apple's cleaning recommendations are here:

How to clean your Apple products - Apple Support

The hard drive auto-cleans and has for 20 years, including defragging. Nothing to do there. Never install any software that claims to clean, tune up, optimize, or anything like that. They WILL inferfere with the elegant, built-in self-maintenance routines you paid Apple to include and WILL cause slowdowns and instability.
