HI,
If you would like to fix the issue without removing the keyboard thenthe best thing to do is turn off your laptop. Then turn it upside down so the keyboard is facing downwards.
Let it stay their for 24 hours. This will allow everything inside your laptop to come out.
Whether
you spilled something or not, your keyboard might begin to start
getting sticky. In this case, the best course of action is to again
shut your laptop down.
Grab a lint-free towel if possible and wet it with water. Rinse it out thoroughly and begin washing your keyboard.
Don't
be worried. Your laptop will be able to handle the very small amount of
water that is around your keyboard when you do this.
After you are done, again grab a lint-free towel if possible and begin drying your laptop.
If the above solution doesn't fix the issue then you can proceed with removing the keyboard.please click on the below link to know how to remove the keyboard with help of pics and also follow the steps below.

DISASSEMBLE
Make a keyboard map so you know where each key goes.
Carefully pry each key loose with a small screwdriver and place in a
container. They pop off. DO NOT use excessive force. There may be a
small rubber piece for each key. Remove all of these and place in a
separate container. CAREFUL, these are small and like to jump away.
CLEAN KEYBOARD ( do this well...... you will be wonderfully rewarded )
Clean the keyboard with cotton swabs SLIGHTLY DAMPENED with water.
Replace these often and BE SURE they are only slightly damp. If they
are too wet the excess water will contaminate the keyboard through
capillary action. This will clean all water soluble contaminants like
Coca-Cola, coffee, and sugar residue. For the very small places, cut
the foam rubber into small pieces and use the tweezers, again SLIGHTLY
DAMPENED, for cleaning. You must clean each and every key space, inside
and out, this is critical since this is where the key touches and
moves.
Repeat this procedure again using rubbing alcohol and cotton swabs but
NOT the foam rubber as it disintegrates when used with alcohol.
Finally repeat this procedure using naptha (lighter fluid) and foam
rubber. You can clean even the smallest key guides with small pieces of
foam rubber and tweezers. This action will remove any petroleum based
contaminants as well as the grease that is sometimes used on the wider
keys which may have guide wires, for example, the SCACE BAR.
CLEAN KEYS
Some keys may have wires attached and some grease on them, clean
these first with cotton swabs and naptha (lighter fluid). Remove all
traces of the grease.
Place all keys in a kitchen strainer. Spray with household cleaner
and let stand for 5 minutes. Rinse thoroughly with hot water and place
keys on paper towels to dry. Let dry completely.
CLEAN RUBBER COMPONENTS
Place all rubber components in a kitchen strainer. Spray with
household cleaner and let stand for 5 minutes. Use stopper in the sink
so that you don�t lose these if they jump out of the strainer. Rinse
these thoroughly with hot water and place on paper towels. Fold the
towels over and press to squeeze most of the water out of the pieces.
Let dry completely.
LUBRICATE KEYS
Place all keys bottom-up on a paper bag. Lightly coat the keys, at
a 45 degree angle with Super Lube Dry Film lubricant. Do this from all
4 sides to assure penetration and coverage into the small and critical
guide spaces inside each key. Let dry ( this happens nearly instantly).
DO NOT overdue this step as the carrier solvent may affect the plastic.
LUBRICATE KEYBOARD
Mask off the laptop with paper and scotch tape. Apply lubricant (as above in LUBRICATE KEYS) to the keyboard and let dry.
All right, you now have perfectly cleaned and lubricated keys, keyboard, and rubber components.
REASSEMBLE
Place all rubber components into the keyboard.
Install keys with wires. Make sure wire is secured in the key,
usually snapped into place. Place ends of wire in the guide slots
adjacent to the key location as you align the key. Firmly press down to
snap the key into place.
Install the rest of the keys by aligning and firmly pressing down.
Thank You
