Cleaning shears between plants
Clear off sap and soil before disinfecting blades, especially after cutting suspect tissue.

Before you start
Check the blade faces and hinge for sap, dirt and plant debris. Residue can get in the way of a disinfectant reaching the blade.
How to do it
Wipe or wash off debris. For compatible hand shears, wet the cleaned blades with 70% isopropyl alcohol and follow the product directions. Keep it away from flames and let the blades dry before cutting.
When to stop and recheck
Use a clean tool on the next plant. If you are dealing with a known disease, check which disinfectant it calls for. Replace or sharpen blades that crush stems.
