Ok, so its for use in food handling. You will see they use vinegar, not 37% acetic acid.
You need to follow that. Your acid is 10X too strong. Many cheap ( home brand) bleaches, if diluted with tap water, will give you what you want. It just depends on what the starting PH of the bleach is. It is governed by how much caustic they add to it to stabilize it.
