Caring for bamboo straw/lid to help prevent mold:

1. All you need is to rinse them out under the tap after everyday use or shake in a jar of warm soapy water if you like. Every month or so, you can boil a pot of vinegar water mix and soak the straws for a few mins if you want a super thorough clean! Always let your bamboo straws dry fully. They dry very quickly!

HOW TO ENGRAVE SILICONE SLEEVE:

Glowforge: uncertified material 700/90/670 or 600/75/675 lpi. Jiffy corn bread box makes a cheap easy filler to hold the sleeve in place while engraving! Just remove the crumb tray and place the box w/sleeve in the bed of the Glowforge!

Mira 9 90 watt: 400/40/604 lpi

Thunder Nova 35/80: 400/40/604 lpi

Scrub silicone sleeve with a toothbrush, water and dawn dish soap after engraving and you are good to go!

As far as taking the silicone sleeve on and off the glass tumbler, water and a little dish soap goes a long way and makes this process super easy!
