There's a lot of fancy gardening supplies out there, I like using some that aren't the most conventional (they're not made for gardening at all! in fact, you probably own most of them already).
Let's just dive right in with the list and skip the jibber jabber. There's ten but since I try not to have favorites, they are not numbered.
Dish soap is a miracle worker in the garden.
You can use it for a lusher, greener lawn (it kills moss but not grass! Please do your research for formula first)
I use it in particular in my bug killing spray! IT KILLS THE DREADED SPOTTED LANTERN FLY THAT'S INVADING AMERICA AND KILLING TREES!!!! Also when I bring plants in for the winter, I like to give them a good dunk in soapy water to kill any bugs and actually enhance the soil.
How does it enhance the soil do you ask? Did you know that the older soil gets, the more water just runs off it? This is called hydrophobic soil. Hydrophobic soil has waxy molecules that keep the water from getting absorbed and the plants from being hydrated. 1 tsp Dish soap (preferably Dawn in the case of pests but any organic/biodegradable will do for this one) per 3 liters of water will give it a nice soak and break down the waxy pieces and change hydrophobic soil into brand new stuff!

Don't get me wrong, this is by no means a complete list of non-garden items and it probably won't be my only list I post.
If you have anything to add please comment! I love to hear new tips and tricks! Also check out some new additions to our inventory!
