I have recently started doing the same. For just a normal multipurpose spray i use a ratio of about 50-50 with vinegar and water and spray. I use bi-carb with vinegar for the tougher things. I’ve been looking around for one of those large plastic salt shakers to make it handy and convenient. Its also great for smelly sink drains…poor in some bi-carb and then some vinegar, get that fizzling and the smell goes away.
