Yes that doesnt look amazingly sterile, especially if you use the same hose over and over, the oil builds up inside the tube?It's actually a little more work than I though.. I don't have a dedicated spot for a lab so I spend a lot of time bleaching counter tops then leaning them with dush soap then rinsing with distilled water and wiping down with alcohol then I spread out painters paper. Then kinda the same process for the equipment I use.. making the dope is quick and easy. Then cleaning everything and putting up..
