🔎 Disclosure: Heads up, babe: some links here are affiliate links, which means you might throw a tiny commission my way if you buy (zero extra cost to you). Only things you’d actually use and love get shared on this site.

1. Leave The Washer Door Open For At Least 1 Hour After Every Load

Okay babe, quick question.

Ever opened your washer the next morning and thought, “Why does it smell like a damp towel monster lives in here?”

Airflow is your bestie here:

• Crack Door Open: Leave the washer door open for at least 1 hour
• Let Steam Escape: Allow trapped moisture to dry fully
• Make It A Habit: Do this after every single load

👉 Here’s How You’ll Do It: As soon as your load finishes, pull clothes out and leave the washer door open for at least 1 hour.

How I Made It Easy: Consider a small door stopper wedge to keep it slightly open safely.

2. Wipe The Rubber Door Seal Dry With A Clean Towel

Girl, that rubber seal hides secrets.

Water sits in those folds and mildew shows up like it pays rent, and we are not allowing that.

Give it a quick swipe:

• Pull Back Seal: Gently lift the rubber edge
• Dry With Towel: Wipe out trapped water completely
• Check Corners Carefully: Remove tiny lint bits

👉 Here’s How You’ll Do It: Grab a clean towel, pull back the rubber seal, and dry every fold right now.

How I Made It Easy: Consider a pack of microfiber cloths for quick seal wipe-downs.

3. Remove Wet Clothes Within 15 Minutes Of Cycle Ending

Let’s be honest, babe.

Leaving wet laundry overnight feels harmless, but mildew loves that cozy dark drum, yikes.

Break the cycle fast:

• Set A Timer: Use phone alert when wash starts
• Transfer Immediately: Move clothes to dryer within 15 minutes
• Rewash If Forgotten: Run quick rinse if clothes sat too long

👉 Here’s How You’ll Do It: Set a phone timer for when the cycle ends and move clothes right away before you scroll.

How I Made It Easy: Consider a loud kitchen timer to keep laundry on track.

4. Run A Hot Empty Cycle With Vinegar Once A Month

Time for a little reset moment, bestie.

A hot empty cycle with vinegar clears hidden residue and keeps smells from creeping in, FYI.

Keep it simple like this:

• Add Vinegar To Drum: Pour one cup directly inside
• Select Hottest Setting: Choose heavy or sanitize mode
• Keep Washer Empty: No clothes during this cycle

👉 Here’s How You’ll Do It: Pour one cup of white vinegar into the drum and run the hottest empty cycle available.

How I Made It Easy: Consider a heat-safe measuring cup just for cleaning cycles.

5. Clean The Detergent Drawer With Warm, Soapy Water Weekly

That drawer gets crusty fast, babe.

Leftover soap buildup traps moisture and smells funky, and nobody wants that surprise.

Freshen it up weekly:

• Remove Drawer Fully: Slide it out carefully
• Wash With Warm Water: Use mild dish soap
• Scrub Small Corners: Clear sticky residue

👉 Here’s How You’ll Do It: Take the detergent drawer out, wash it in warm soapy water, and dry it before sliding back in.

How I Made It Easy: Consider a small detail cleaning brush to scrub drawer corners.

6. Use The Correct Amount Of Detergent For Each Load

More soap does not mean cleaner clothes, girl.

Too much detergent leaves residue behind and that sticky film feeds mildew, which is rude.

Measure it right:

• Follow Label Guide: Check load size instructions
• Use Measuring Cap: Avoid guessing amounts
• Reduce For HE Washers: High-efficiency machines need less

👉 Here’s How You’ll Do It: Check your detergent label and measure the correct amount for your next load instead of eyeballing it.

How I Made It Easy: Consider a marked detergent dispenser cup for accurate measuring.

7. Avoid Overloading The Washer With Heavy Towels

I know, stuffing it full feels productive.

Overloading traps moisture between thick towels and creates damp pockets that mildew loves.

Keep loads balanced:

• Leave Space On Top: Allow room for water movement
• Wash Heavy Items Separately: Do towels alone
• Shake Towels Before Washing: Spread fabric evenly

👉 Here’s How You’ll Do It: Next time you wash towels, fill the drum only three-quarters full and let them move freely.

How I Made It Easy: Consider a laundry sorting basket to separate heavy loads easily.

8. Dry Around The Door Frame And Hinges After Washing

Those edges get ignored, babe.

Moisture hides around hinges and frames, and mildew creeps in quietly if you ignore it.

Detail dry the area:

• Wipe Door Edges: Use dry cloth around frame
• Check Hinge Area: Remove trapped droplets
• Dry Bottom Lip: Focus on lower rim

👉 Here’s How You’ll Do It: After each load, run a dry cloth along the door frame, hinges, and bottom rim.

How I Made It Easy: Consider a slim cleaning cloth wand for tight hinge spaces.

9. Clean The Drain Pump Filter Every 30 Days

Okay bestie, this one sounds scary but it’s not.

A clogged drain filter traps lint and moisture, and that combo equals mildew party time, nope.

Stay on schedule:

• Locate Bottom Panel: Open access door carefully
• Remove Filter Slowly: Twist and pull gently
• Rinse Under Sink: Clear lint and debris

👉 Here’s How You’ll Do It: Open the bottom panel, twist out the drain filter, rinse it clean, and put it back securely.

How I Made It Easy: Consider a shallow drain pan to catch leftover water neatly.

10. Keep The Laundry Room Door Open To Improve Air Circulation

Air circulation matters more than you think, girl.

Stuffy laundry rooms trap humidity and make mildew show up faster than you can blink :).

Let the room breathe:

• Open Door Daily: Keep it cracked when possible
• Run Ceiling Fan: Improve airflow inside
• Avoid Storing Wet Items: Keep damp towels elsewhere

👉 Here’s How You’ll Do It: Leave your laundry room door slightly open during the day to let fresh air circulate.

How I Made It Easy: Consider a small box fan to boost airflow in tight laundry spaces.
