I think a wipe in between plants with an antiseptic wipe is sufficient. I think that is the RHS advice to clean between plants, they might recommend a substance, but I don’t think you need to leave them soaking in anything.
Here’s what I found on the RHS for you
Quote
“ Apply a suitable disinfectant such as Jeyes fluid, Citrox or Propellar to all used blades. To successfully kill pathogens, leave for 15-20 minutes before wiping off
Dry with an old towel and then oil, remembering that any brush or cloth should also be disinfected
Don’t forget your boots, remove contaminated soil and disinfect the soles”
