I have purchased new 750 mL brown plastic bottles from a local Beer Brewing supply shop for use in a root beer project.
Does any one have suggestions on what needs to be done to these bottles prior to the first use to "clean" them?
What about subsequent cleaning between batches?

Thanks.

Wash them out in the sink to get rid of plastic residue and dust and whatever else might have got in. Then sanitise them. You local brewery supply shop should have sanitiser like B-T-F available. Get a bucket from your local Home Depot, mix up a batch of B-T-F and soak the bottles for the required time. Shake them out set them up and go to bottling. You can wait for the bottles and caps to dry a bit.
