Frugal? Is it worth it?

Frugal tile cleaner.  I have all the ingredients at home, so...
I chose the baking soda and bleach method.
Did it work?  Yep sure did.  Looks great.
Would I do it again?  NOPE. Even with the window open, the fumes got to me.  Burned my throat.
Next time I will try the vinegar, lemon juice and baking soda.
Now, yes it is frugal, but it is work.  I scrubbed those bathroom tiles for two hours. And it took a couple moppings to get all the residue off.  I have the smaller hall bath to do next.  We well see how it comes out.
Picture is blurry, but you can see the difference 

Left it clean, right is dirty
