I bought an inverter for my boat. The unopened box got splashed with sea water. NOT SUBMERGED. I removed the inverter (which was dry) and let it sit for a couple of days just in case. Upon installing, it works fine for 100w USB side but cuts out using 1000w side. No visible corrosion anywhere but I have not opened it up. Should I try a distilled water bath then alcohol bath to pull any salts? Suggestions before I crack it open? - thanks
