Hello; Probably not a bad idea at some point in the future especially when the parasite issue is fixed. I was thinking of the day to day use of equipment which will be necessary while the weeks long treatment of the ich is ongoing.
If you bleach such things as nets right now they will have to be de-toxed in something such as PRIME before used again. Then if used in the infected tank will have to be bleached again.
Not sure how effective it was but a fish shop back in the 1960's use to have a rack of tanks with small containers hanging on the outside. Those small containers had what I think was a solution of MB (may have been some other chemical) in which the catch net were kept. After catching a fish for sale the nets were stuck back into the solution. I figure it was something that at the least killed off bacterial and fungal pathogens and maybe the vulnerable stages of ich?
