As per @BigOnYa recommendation via a YouTube video I decided tonight is the best time to carry out the cleaning of my JoyCons.
2x cotton earbuds.
1x can of electronic contact cleaner.
Here is the video that @BigOnYa shared.
For those who wants a quick rundown.
1. Detach both JoyCons (of course).
2. Moisten up them buds with the cleaner.
3. Under the analog there is a rubber skirt, pull it up.
4. Clean the heck out of it, I go in circular motion.
The bud did turned slightly black in color, dust & dirt I guess? After that for extra measure cause I love being extra I sprayed on under the thumb surface then I rotate the stick in circular motion for 30 seconds as per the video.
Leave it to dry for 5 mins then I re-attached and gonna try out the analog tomorrow.
I will still purchase a HORI Split Pad Pro as @Silent_Gunner recommended cause that looks so comfortable to hold and I found a cute black/gold Pikachu edition, why not?
I love you all!
