How safe is it?
Washing soda is quite strongly alkaline so you should not let it be in contact with your skin. Use rubber gloves when dealing with it. It is classed as an irritant and is particularly irritating to the eyes.
You should also avoid breathing the dust. As it is usually supplied as a crystal, this isn’t hard to do. Once it is dissolved in water it doesn’t give off toxic fumes.
