I accidentally used a cloth with 40% isopropyl alcohol to clean my laptop keyboard, and several keys stopped working. I left the laptop open for two days, and every key worked normally when I first powered it on. A couple of hours later, some keys had stopped responding again. Is it worth filing a warranty claim, and should I be worried about corrosion or further damage?

A standard warranty usually covers manufacturing defects, not liquid or cleaning-fluid damage. The service center may be able to identify liquid exposure during inspection, so approval is unlikely unless you bought accidental-damage coverage.
Forty-percent isopropyl alcohol contains a substantial amount of water compared with the high-purity alcohol normally used for electronics. If the keyboard is still unreliable after drying, the keyboard assembly or its membrane may already be damaged and could need replacement.
It is still worth contacting the manufacturer to ask about coverage, but describe it as a cleaning-related incident rather than expecting it to be treated as a normal warranty defect. Accidental-damage protection would be the more relevant type of coverage.
The changing behavior suggests there may still be residue or moisture around the keyboard or its connector. Avoid turning it on repeatedly, disconnect the battery if you can do so safely, and have it professionally inspected and cleaned. Corrosion can develop later, especially if the fluid contained impurities.
