Here is a great way to keep all your cleaners organized under the sink. Buy a short shower curtain rod and install it under your sink, make sure it is in there tight. Then, place all of your cleaners that use a spray nozzle on to rod.
This rod keeps all the cleaners up off the bottom of the cupboard, leaving room to for other things. I have a cleaner caddy under there that I have all of my cleaning tools in, such as sponges, brushes, and steel wool.
Note: I haven't had any trouble with the rod slipping down, but I thought that if I did start to have that problem I could fix it by buying the cups that hold the closet bar in place and use those to also hold the shower curtain rod in place.

I always take one metal rack out of my oven because I usually don't need it in there. I store it under my kitchen sink standing it vertically and leaning on the drain pipes.
An ordinary sink has what I call a "hell hole" under it. Sure, you can buy expensive organizers, but when money is tight, consider these means of organizing things.
I recently found an under sink rack on clearance. Previously all of our cleaners and things were in a crate under the sink and took up a lot of space and were difficult to get to.
I like to use the cardboard cartons from a 6-pack of beer bottles to hold various items. Occasionally DH buys the 4-packs of larger bottles and those work well for larger items.
I was sorting out my cupboard under the sink, which is full of assorted cleaning stuff, aerosols etc. and general clutter. I wanted some plastic boxes to tidy things into before putting them back.
Vinegar, baking soda, dish detergent; that's about all the cleaning products I use in my kitchen other than a few SOS type pads.
