There's no doubt about it: Figuring out how to organize that messy area under your kitchen sink once and for all is a tall task. From your army of household cleaning solutions to your dishwasher detergent and back-up sponges, it's one of those pesky areas of your home that is prone to collecting clutter — which can make keeping it neat and tidy feel downright impossible.

In order to conquer the chaos at last, you'll need to think strategically. These organizing tips, plus must-have tools and organizers, will help you streamline your under-sink storage space in no time.

How to Organize Your Under-Sink Space, Step-by-Step

1. Empty out the entire cabinet.

The best place to start is with a clean slate, so begin by removing everything and giving your under-sink area a thorough wipe-down. With everything out, you can see how much under-sink storage space you actually have. (It's been a while since you've seen it all, right?) This will help you visualize how much space you're working with and allow easier measuring for the organizers you might want to buy. You can also review expiration dates, check for dried-out wipes, and combine half-empty bottles to save even more space.

2. Install a waterproof liner.

Since the area under your sink could come into contact with water or other liquids, cover the base of your cabinet with a waterproof layer of adhesive vinyl paper ($6; target.com) or leftover laminate flooring ($1; lowes.com). This can help prevent costly damage from occurring in case of a burst pipe. If you notice some water damage, stop what you're doing and inspect for leaks. Small drips can turn into bigger problems if they're not handled immediately and properly.

3. Pare back your inventory.

With all of your products out in the open, take stock of your inventory. Ask yourself what you should keep, what you can toss, or even what you might need to refill.

To cut back on under-sink clutter, most people can get by with this short list of only the most essential cleaning supplies and tools:

Rather than buying individual bottles of each cleaning product, consider trying an all-in-one soap concentrate that you can use to create every cleaning solution you need just by varying the measurements. For example, this starter kit from Branch Basics makes all-purpose cleaning, bathroom cleaner, streak-free glass cleaner, laundry detergent, and dish soap.

4. Organize your under-sink area by grouping like items together in drawers or bins.

Rather than lining up bottle after bottle of cleaning solution along the bottom of your under-sink area, make them look more organized by corralling them into a durable under-sink organizer.

But if you're going for an even more streamlined look, concealing the clutter in a set of mesh drawers or stackable wire drawers is your best option — just don't forget to save some room for all your loose rags and sponges, too. These drawers also have removable separators if you wanted to divide supplies by task or room.

5. Create more under-sink storage space by hanging smaller items from hooks.

Lastly, install removable hooks ($4; walmart.com) inside the cabinets under your kitchen sink to keep lightweight, smaller items — like gloves and dish scrub brushes — up and out of the way, while still being easily accessible.
