To sanitize beer bottles, wash and scrub the bottles using hot water and a strong detergent. The bottles can be rinsed in a sink, or you can use the rinse cycle of the dishwasher. The process takes less than one hour.
Gather the bottles
Place all the beer bottles in a large bin. Put all the bottles on their sides to fit as many bottles into the bin as possible.
Add detergent and water
Add hot water and a powder or liquid detergent to the bin to clean the bottles. Leave the bottles in the detergent solution for at least 30 minutes.
Scrub the bottles
Use a wash cloth or brush to scrub the bottles. You can also use a thin bottle brush to clean the inside of the bottles.
Rinse the bottles two or three times to make sure there is not detergent residue left on the bottles.
