Tommy I wouldn't use it for hypo personally

Use a stiff brush

If you are having to agetate excessively you should clean it with a washer first.
With a 2% pretreatment before you wash

And a 3 to 5% for the spores and remaining lichen colonies.

I have done 1000s of meters like the above and never needed to use a crb.

I don't know if any of the rubber seals or plastic on it would react with the hypo either.
