What is the shelf life of homemade cleaning supplies?

Question

I often make baking soda, vinegar, borax,lemon juice, etc. products for my own home. I am trying to start a small cleaning business. Usually, when I make these for home, I do it on the day I will be cleaning... how long would these supples last if I made them batches at a time?

Answer 1

Most of those ingredients will last months if not years.  The only thing that may degrade is the lemon juice.  But it still must be good for weeks.
