For the bottles, clean and rinse, then bake in the oven. I put the bottles in and set the temp to 350, then turn off and let cool. For the caps, spray with rubbing alcohol and wait 30 seconds. Spray tubing and cane and wand inside and out.
UNSCENTED bleach is an option. Bleach will sanitize, but must be rinsed out with hot water. Look for the bleach with the most chlorine. It is sold in at least two concentrations. Look up the various sanitizers on the internet. Check with local bars and resturants for what they use. I doubt you would be refused if you wanted to purchase a small amount.
