Because standard gasoline or diesel containers don’t seal properly, they mean that any product inside will vaporize once opened which leaves them open to contamination by water and other impurities even when sealed back up again. However, with our specially designed bottles your home made bioethanol won’t evaporate meaning you get more mileage out of each refill while ensuring it remains free from dirt and debris too! Plus if stored correctly (in a cool, dry place), our bottles can last up to five years which means you won’t need to keep buying new ones every time you want bio ethanol for your fireplace.
