Welcome to Day 21 — and the final space of Week 3. Three full weeks of intentional decluttering, one space at a time, and today we’re tackling your car!

I know. It’s not the first place that comes to mind when you think about decluttering your home. But here’s the thing — your car is one of the spaces you spend the most time in every single day. Errands, school runs, appointments, adventures, the sing-alongs and the conversations that happen when everyone is looking forward instead of at each other. For a family with a toddler, the car is genuinely where a lot of life happens. And it deserves to feel as calm and intentional as the rest of your home.

The Most Overlooked Space in This Challenge

The car accumulates in a way that’s almost imperceptible until suddenly it isn’t. Receipts from three weeks ago. Water bottles that have been rolling around since Tuesday. Snack wrappers. A book Ollie carried in and never carried back out. The particular collection of small debris that comes with having a toddler in the backseat and living a full and active life.

None of it arrives all at once. It just quietly gathers, day after day, until the car stops feeling like a calm and functional space and starts feeling like somewhere you’re just passing through rather than somewhere you actually want to be.

A decluttered car changes that. And it takes less time than almost any other space in this challenge.

Our Car Organization Approach

I want to share what actually works for us, because I think the specific details are genuinely useful here.

Tossits car garbage bags are my absolute secret weapon for keeping the car clean with a toddler. Rather than a bin that can get gross, tip over, or have leaks — which is a very real concern when your passenger consumes approximately one applesauce pouch per car ride — Tossits are individual, leak-proof disposable bags that hang right in the car. They’re genuinely brilliant for toddler families and one of those products that once you try it, you wonder how you managed without it.

A woven bin in the backseat corrals Ollie’s books and toys so they have a designated home rather than migrating freely around the back seat and floor. Just like toy rotation at home, I rotate what’s in the bin every couple of weeks so it feels fresh and engaging. A car that has a small selection of genuinely interesting things for Ollie is a car that makes longer drives so much more manageable.

And then there are the stickers. Ollie’s car seat has accumulated the most wonderful collection of stickers from all of our adventures — the library storytime, various outings, little moments that left a sticker behind. I’ve decided those are staying exactly where they are. They’re a little record of everywhere we’ve been together, and I love them completely.

How to Declutter Your Car Today

Give yourself 20 to 30 minutes for this one. It goes quickly and the result — climbing into a clean, calm car tomorrow morning — is immediately and completely worth it.

Step 1: Take everything out. Every single thing — from the seats, the door pockets, the cup holders, the glove compartment, the trunk. Lay it all out so you can see what you’re actually working with. This step is always a little surprising.

Step 2: Vacuum or wipe down every surface. Seats, floor mats, cup holders, the dashboard. A clean car feels completely different from a tidy-but-dusty one. Take the time to do this properly — it makes such a meaningful difference.

Step 3: Sort everything honestly. Trash goes immediately. Items that belong in the house go in a pile to take in. Items that genuinely belong in the car get a designated home. Be honest about what actually needs to live in the car versus what has just been living there by default.

Step 4: Invest in a car garbage solution. If you have a toddler and don’t have a system for car trash — today is the day to get one. Tossits car garbage bags are genuinely our favorite solution for exactly this situation. Leak-proof, individual, no bin to clean. They make keeping the car clean so much more manageable day to day.

Step 5: Create a designated spot for your toddler’s things. A small woven bin, a backseat organizer, or even a simple tote — something that gives their books and toys a consistent home so they’re always contained and always findable. Rotate what’s in it every couple of weeks to keep it feeling fresh.

Step 6: Keep the glove compartment functional. Registration, insurance, a pen, a small first aid kit — the glove compartment should hold only what genuinely belongs there and needs to be accessible in the car. Clear it out and restock with intention.

Step 7: Establish one simple rule going forward. The rule that keeps a car clean is the same one that keeps any space clean: things come in, things go back out. Trash gets taken in when you go in. Items that belong in the house travel with you when you leave. One simple habit maintained consistently is all it takes.

The Car You Deserve to Drive

Tomorrow morning, when you climb into a clean and considered car — when the cup holders are clear and the floor is vacuumed and Ollie’s books are in their bin and there’s a fresh Tossit ready to go — I hope you notice how differently it feels to start the day. Your car is part of your home. It deserves the same intentionality and care as everything else we’ve decluttered over the past three weeks.
