How to treat Gladiolus corms?

BML

I've just lifted some Gladiolus corms with a number of small white round attachments. Looking at a video on the Web I note that the presenter made up a solution of I know not snapped the stem of the corm and dipped the corms in the solution.  They then pulled off the small white round things and treated them with the solution as well and then I lost the video.  Could anyone advise me what, if anything the corms should be treated with and what happens to the small white attachments, do they grow into anything?

They grow into more corms 

Sorry - can't help with the solution.

The solution will have been some sort of fungicide I expect.  Not really needed as long as the corms are clean and dry when you store them somewhere cool, dry and frost free.  The little white bits are offsets and, given the chance, will grow to full flowering size if planted again next spring.

Here's what the RHS says about caring for gladiolus, from planting in spring to lifting in autumn - https://www.rhs.org.uk/Plants/152241/Gladiolus-Green-Star-(L)/Details

I have a relative - https://www.rhs.org.uk/Plants/182096/i-Gladiolus-murielae-i/Details which I now leave in the ground as winters here are shorter and usually mild enough to risk it.
