I've got the jug right here in front of me. There's no bleach in it. What
are the contents of the jug you have?

I'm looking at their website. And the official documentation. Not the lying
label. The MSDS is the only real way to tell what any product has in it.
The labels are always disguised with laymens terms.

Sorry, but I've used bleach & water AND I've used JOMAX+BLEACH+WATER ..
.. .. the JOMAX blend is much quicker-acting and thorough without a
doubt. Try just a quart of it for yourself and I think you will see
there is a difference.

I have some lumber that came with some green mold. I may just do that.

Watch the weather forecast. Do this when 3 or more days of dry weather is
anticipated. Use a powerwasher with bleach added. You don't need extreme
pressure. Wait 8 hours. Rinse well. Wait 3 days. Apply your Tyvek or
whatever.

If the mold is actually growing on the backside of the sheathing and on the
studs, you may have to replace it due to your sensitivities. Pull one sheet
off on the worst area you find to find out.

If you were, you would not be breathing now. Maybe more sensitive than the
general population is more appropriate?

When I was young, I was overly sensitive to "cedar" pollen during cold
weather snaps. Actually is juniper ashe in south central TX. Made me
miserable. My body has adjusted to it over the years. Have averted from
"allergy" medication.
