NOPE
Can I wash my laptop?
No. Your laptop is not a plate, even if it currently has crumbs like one.
Do not wash a laptop with water, soap, or the confidence of someone about to buy a new laptop. Power it off, unplug it, use a lightly damp microfiber cloth on the outside, and keep liquids away from ports, vents, and the keyboard.
If liquid got inside, power it off, unplug it, and get qualified repair help before turning it back on.
