How to disinfect cell/tissue culture surfaces
- Use 70% isopropanol to wipe all the surfaces
- Additionally use 70% ethanol if you worked with viruses
- Use 10% bleach if you spilled virus.
- First clean the surface with tissue papers
- Clean with 70% ethanol and dry with tissue papers
- Clean with 10% bleach (You should incubate metal surfaces with 10% bleach no more than 5 minutes)
- Wipe with tissue papers
- Clean with excess 70% ethanol to remove all the residual bleach
- Both ethanol and isopropanol are very effective at 70% concentration, higher and lower concentrations are less effective.
- 70% ethanol is effective against most viruses except non-enveloped viruses
- 70% isopropanol is not effective against viruses but better disinfectant than 70% ethanol for bacteria, yeast and etc.
