Read for step-by-step instructions:
To repair a liquid damaged and battery acid damage TI-84 Plus Silver Edition you need 91% rubbing alcohol, a soft bristle tooth brush, a Philips head screw driver, a t6 torx, and a towel. Take apart the calculator and clean the residue from the liquid off of the motherboard of the calculator with the rubbing alcohol and let it evaporate. Clean all the non-electrical parts of the calculator with soap and water. Pop the battery contacts out of the calculator case with your fingernails or a flat head screw driver and clean them with the tooth brush and rubbing alcohol. If they are corroded use steal-wool to remove the corrosion and rub dielectric grease on the contacts to prevent future corrosion. Let the calculator parts you washed dry and let the rubbing alcohol evaporate and put the calculator back together.
