Disinfecting Tools

Disinfecting Tools, Equipment, Pots, Flats, and Benches - by Gary W. Moorman, PSU Cooperative Extension Dept. of Plant Pathology.


"Your disinfecting solution can contain any of the sanitizing products such as Green-Shield, Physan 20, Triathlon, Zero Tol or chlorine bleach (10% solution). Be sure to follow the manufacturer’s directions when using any commercially prepared materials. If you are using a 1 to 9 bleach solution, remember that it requires a 30-minute soak in order to be effective. Also - while chlorine bleach is an effective sanitizer, please note that there will be a 50% reduction in strength of a chlorine solution after just two hours. Therefore, you should prepare a new solution each time you plan to sanitize." (Quoted from PSU Dept of Horticulture The Vegetable and Small Fruit Gazette Vol 6 No.1 Jan. 2002)  When using cholrine bleach rinse metal objects to prevent corrosion.


Another option is to soak a hand tool in a 70 - 80% solution of alcohol, ethanol or isopropanol, for 10 - 15 minutes to disinfect the tool. Alchohols are bactericidal and fungicidal. Prescott, Harley, & Klein's Microbiology, McGraw Hill 2008, p159-160.
