After the oil is heated, pour it into the mixing bucket. The bucket must be completely dry and free of any residue. The residue of any substance left behind can upset the delicate reaction and ruin the batch of biodiesel.
We like to use recycled 5 gallon spackle buckets or restaurant supply buckets. If you're going to use a bucket made out of other materials, you'll need to test it first to make sure it can withstand the biodiesel reaction.
