Remember to take note of what temperature the onesie needs to be washed at. This is usually indicated by a number ranging from 0-95 degrees Celsius and can also indicate the washing cycles it should go through or the type of detergent to use.

2. Choose The Right Detergent

When picking out the best detergent for your baby’s onesie, always go for natural detergents that are formulated specifically for the baby’s sensitive skin. Avoid harsh chemicals and opt instead for gentle detergents that are free of dyes and fragrances.

3. Choose the Right Temperature

When it comes to washing a onesie, using the right temperature is key! If you’re washing the onesie in a washing machine, make sure you set the temperature according to what is indicated on the label. Generally, it’s best to stick with a lukewarm or cold cycle for baby clothes.

These are just some of the tips on how to wash a onesie correctly. With proper care and maintenance, your baby’s onesies will last longer and stay looking their best.

How to Wash a Onesie in 10 Easy Steps 

Step 1: Check the Label

Before you start washing your onesie, make sure to check and read the care label thoroughly. It’s important to know what type of fabric it is made out of so that you don’t damage it during the cleaning process.

Before Washing Onesie Check Care Label

Depending on the material, some fabrics may require hand-washing or dry-cleaning instead. Most onesies are machine washable, though, so make sure to check the label first.

Step 2: Pre-treat Stains 

Before you begin washing your onesie, it’s important to treat any stains or dirt marks that may be on it. Use a mild detergent and gently scrub the fabric in a circular motion with a soft cloth or brush.

Step 3: Set the Machine 

Set your washing machine on a gentle cycle with cold water. Make sure to also set the spin speed on low so that it doesn’t damage the fabric or cause it to shrink in the wash. The machine should also be set to a gentle or delicate cycle setting if available.

Step 4: Load the Onesie 

Once you’ve set the machine settings, it’s time to load your onesie into the washing machine. If you have a mesh laundry bag, use that, as it will help protect the fabric and keep it from getting tangled in other items.

Step 5: Add Detergent 

Add a mild detergent to the machine according to the instructions on the label. It’s important not to use too much detergent as this can cause excess suds, which can damage your onesie. Detergent also helps to remove any stains and dirt.

Step 6: Wash Cycle 

Start the washing cycle and let it run for a few minutes. Make sure to check on your onesie every now and then to ensure it’s not getting tangled up or snagged on any other items in the machine. Adding a small amount of white vinegar to the wash cycle can help keep colors from fading over time.

Step 7: Rinse Cycle 

Once the wash cycle is finished, start up the rinse cycle and again let it run for a few minutes. This will help remove any excess detergent or dirt that may have been left behind. Rinsing your onesie will also help make sure that the fabric is soft and smooth after it’s been washed.

 Rinse for Few Minutes to Remove Excess Detergent

Step 8: Spin Cycle 

When the rinse cycle is finished, start up the spin cycle to remove excess water from your onesie. Make sure to set this on low to avoid any damage or shrinkage due to too much spinning. You may have to do this cycle more than once if your onesie is still very wet.

Step 9: Dry Cycle 

Once the spin cycle is finished, it’s time to start the dry cycle. Set the machine on a low heat setting and let it run for an hour or two. To protect your onesie from shrinking, you can also hang it up on a drying rack or line dry it if possible.

Step 10: Final Touch 

After your onesie is completely dry, give it one more check to make sure that it’s not wrinkled or misshapen in any way. You can also give it a final press with an iron if needed.

And there you have it! Following these steps will ensure that your onesie will last you for years to come. Now you’re ready to flaunt your stylishly comfortable outfit in style!

5 Maintenance Tips for Cleaning Your Onesie

Onesies combine style and comfort, making them one of the most popular items of clothing. However, as with many pieces of clothing, proper maintenance is essential to ensure that your onesie remains in top condition and lasts for years to come.

Here are 5 simple tips to help keep your onesie looking its best:

  1. Read the care label. Before you start washing a onesie, be sure to read the care label carefully for any specific instructions from the manufacturer on how to properly clean it. Following these instructions will protect your onesie and help keep it looking its best for longer.
  2. Check for color bleeding. To check if colors are likely to run, turn the onesie inside out and soak it in cold water for 10 minutes. If you notice any color bleeding, use a separate detergent for colored clothing or choose a color-safe bleach if necessary.
  3. Separate your laundry. Unless your care label specifies otherwise, always wash similar colors together to avoid the risk of colors running onto other items. It is also a good idea to zip up or close any zippers on your onesie before washing it.
  4. Use the right detergent. Choose an appropriate detergent for your onesie. For synthetic fabrics, choose a detergent formulated specifically for delicate fabrics, such as those labeled as “for hand wash” or “for delicate fabrics”. If the onesie is made from natural fibers, such as cotton or wool, you should opt for a detergent specifically designed for those materials.
  5. Wash with cold water. Hot water can damage delicate fabrics, so it is best to use cold water when washing your onesie. For an extra-gentle wash cycle, try a delicate, hand-wash, or wool cycle if your washing machine has one.
Use the Right Detergent

Following these simple tips will help keep your onesie looking its best over time and ensure that you get the most out of it. With proper care and maintenance, you can enjoy wearing your favorite onesie for years to come!

Hi, my name is Loren. I live with my husband and 4 lovely kiddos in the Eastern part of San-fransisco. I have a smart beautiful,curious 6 year old daughter, a handsome 11-year-old son, an intelligent and tech geek 15 years old son and a creative, artistic 12-year-old stepson. With each of my kids being five years apart, I feel that I’m now continually phasing in and out of each stage of parenting! I’ve learned a lot about the way children learn and behave, especially in a school setting with regards to curriculum. I enjoy sharing that insight through my writing and hope that it can help others.
