So from what I've heard, cleaning products are in a REAL shortage. So, I'm here to help you with basic ingredients you CAN find, so you can make your own.
First off - spray bottles. I highly recommend brown glass over plastic. The bottles pictured are available and (as of publishing of this post) in stock on Amazon. Grab your link here: Brown Glass Spray Bottles.
Now that you've got your bottles, let's talk cleaner options.
It really comes down to vinegar or vodka in my book. Vodka is more for drinking in our house, but either solution will work! Please note the vinegar I am using is distilled white vinegar.
Requires 1 part water (preferably filtered), 1 part vinegar, plus your favorite essential oils if that's your thing - it can make it smell better! Basically pour in 1 part water (eg 8 ounces), 1 part vinegar (eg 8 ounces) and anywhere from 10-20 drops of essential oils of your choice. I personally use Rocky Mountain Oils Immune Strength (their version of Thieves - but they have free shipping on EVERY order $25+ and there's not a consultant/sales model). Buy it here if you're interested: Immune Strength Essential Oil Blend. Always spot treat an area before using, although vinegar based solutions are known to be friendly to all surfaces except marble!
Requires 1 part water (preferably filtered), 1 part vodka - (for CDC compliance, vodka should be at least 120 proof), and 20-30 drops of your favorite essential oil (optional). Same as above, but substitute vinegar for vodka!
Best of Both - Vodka Vinegar Blend:
If you have the means, some suggest this is the best option! 3 parts vodka (eg 12 ounces), 1 part vinegar (eg 4 ounces), and 20-30 drops of your favorite essential oils. Mix in a glass bottle, and remember to spot test!
I hope that helps! There are a lot of other options out there that involve soaking lemon peels in vinegar for two weeks, etc, and I think those are perfectly good formulas, but these give you blends you can use as soon as they're mixed.
