My piano does not work anymore (read description) what should i do please ?

ok, its a real piano not an electrical one. I was trying to clean it with baking soda and water, and hydrogen peroxide. Now my piano keys do not go down anymore, they are sluggish and stay down and they stick together. I sprayed the solutions on the keys and they went inside in between the keys . The piano keys got soaked becuase i pretty much poured it. Im so stupid i didnt know that was bad so what should i do now ?
