Salad dressing spill

I should’ve been more careful with leaving stuff out but my cat knocked over an open bottle of sesame salad dressing onto the laptop keyboard. I cleaned around the affected keys with alcohol and q-tips as best as I could. A few keys still feel sticky and hard to press.

Is there anything else that can be done or should I just take it to a repair shop to get it professionally cleaned? The key caps don’t seem to be removable and I don’t trust myself to open up the laptop.
