macdaddy36 Posted June 27, 2022 Share Posted June 27, 2022 How do you clean water test tubes after use? Should I just thoroughly rinse them out? Link to comment Share on other sites More sharing options...
Scapexghost Posted June 27, 2022 Share Posted June 27, 2022 Mix white vinegar and distilled water. The exact ratio isn't too important but you should use much more water than vinegar. Rinse with this solution and let dry completely. Link to comment Share on other sites More sharing options...
Scapexghost Posted June 27, 2022 Share Posted June 27, 2022 *poor a couple ml of the solution into the tube, cap it, and then shake vigorously. Link to comment Share on other sites More sharing options...
Brian Posted June 27, 2022 Share Posted June 27, 2022 Shop Aquariums Co Op and purchase test strips. When I used them I just rinsed 3 or 4 times tap water and let air dry. Link to comment Share on other sites More sharing options...
