I have cut my supplies down to the bare minimum. At this time I only am using vinegar, comet and occasionally bleach.
In an old windex bottle I have a mixture of 1/3 vinegar to 2/3 water. I use this for mirrors and windows. I also use it for wiping down the kitchen table and counters.
Comet is super cheap and I think it works best if you have a stain on the counter top or in the tub. Now if you have certain types of countertops you will probably have to clean with something else.
When I mop the kitchen floor I either do a mixture of vinegar and water or bleach and water. Just depends on how dirty I feel the floor is. If I think it is really bad I drag out the bleach.
I also use comet for the toilet bowl. I use my vinegar spray for the exterior of the toilet and the bathroom sink.
I have started looking into all the things I can do with baking soda, it is super cheap and great for many cleaning projects.
