Downstreaming sodium hydroxide

going to apply some sodium hydroxide to some siding, how concerned do i need to be with glass? i’m obviously not going to apply directly but should i tape the glass off or something?

Why are you using SH on siding?

+1 ?

To remove stain

Oh, it’s this for the house you posted about earlier?


I’d tape the glass off, that stuff can be nasty and the extra time covering your butt will be worth it.

I would rather take the time to tape the windows and not need to rather than not tape them and then wish I had.
