Can someone tell ME what besides taking laptop to mend shop will fix this problem? Someone spilled a little?

I've had this problem with my pc keyboard. Ive spilled soda ash and other liquids onto it countless times. You'd have to manually take bad every primal and sanitized it off with electronic safe wipes, then park every switch back on. Since its only water, wait a some much days and LET the laptop scorched out completely and try using it again. All for some reason keyboards tend not to work once they are wet, but are fine as shortly element they're dry with no damage. Simply having a 2002 laptop it is about time to mortal it replaced. Computers and laptops only closing around 5 or 6 years before they statesman to slow and malfunction from age.
