How to Clean Antifreeze Out of Carpet?

When it comes to cleaning antifreeze out of carpet, it’s different. You can’t treat it like any other stain. At the end of the day, antifreeze is a greasy product no matter how you see it. Moreover, you don’t want antifreeze poisoning.

So, here are the steps you need to follow to clean antifreeze out of your carpet-

Step 1: Remove Excess Antifreeze

Remove as much antifreeze as you can. This will make the cleaning process much easier. You can do it with a paper towel or a clean white rag. 

But avoid putting any extra pressure or rubbing on the carpet to prevent it from spreading even more. Continue soaking up the antifreeze until the paper towel will no longer absorb.

However, make sure to do it fast. Once the antifreeze gets deep into the fibers of the carpet, there’s no going back. Then you’ll have to bring in a professional carpet cleaner. And if you don’t want to spend a lot of money, avoid it.

Step 2: Pour Hot Water Over the Stain

Hot water is great for removing caramel stains and other kinds of stains. Sometimes it’s all you need. While that won’t be the case in this situation but it will help to lay the base.

First, put paper towels or clean rags around the stain.  Then slowly begin to pour hot water over the stain.

But make sure you don’t pour all of the water at the same time. That’s going to make the mess even bigger. Continue pouring the water for 3 to 4 minutes and you’ll see the stain has lightened up.

Finally, vacuum the carpet to dry it out.

Step 3: Apply a Degreasing Carpet Cleaner

Make sure you read the instructions manual before you apply the degreasing carpet cleaner. It’s not every day that you use a degreasing carpet cleaner so read the instructions manual to know how you can use it. After that, mix it with water.

Before you apply the cleaner on the stain, (assuming it’s not a small area) do a patch test. Apply a small amount of the carpet cleaner to an unnoticed part of the carpet. 

Stop immediately and clean up the area if you notice any discoloration or damage on the carpet.

If the patch test is okay, then you can proceed. Properly mix the carpet cleaner with the carpet fibers. Don’t rush while you apply the carpet cleaner. 

After you’re done, grab a newspaper because you need to wait for 10-15 minutes.

Step 4: Apply a Vinegar Solution

The vinegar is for removing both the smell of the antifreeze and the degreasing carpet cleaner. For making the solution, you need ⅓ cup of vinegar and 2-3 cups of water. 

You don’t need distilled water for the solution. But if you’re willing to go the extra mile then who are we to stop you, right?

Pour the solution in a spray bottle and start spraying it on the stain. Now don’t go all out with spraying the solution. Only use so much that it’ll dampen the carpet. 

You see, using too much vinegar will only make the process longer as you have to clean that too.

Step 5: Sprinkle Some Baking Soda

The baking soda is also for neutralizing the smell. Trust us, you don’t want to skip this step. Simply sprinkle some baking soda over the stain and let it sit overnight.

Step 6: Rinse and Dry

First of all, pour a little clean water over the area. This will help to dilute the cleaner and other things you used. After 2-3 minutes of waiting, wipe the water with a clean cloth or a paper towel.

It’s time to dry it out after the area has been rinsed. Don’t forget that you need to dry out the carpet as soon as possible. But if you’re fond of fungus and bacteria in your carpet, you can let sit for as long as you want.    

Although you can turn on the fan to dry it out quickly. You can also use a few silica gels instead of a fan. Those do a good job of soaking up liquids.

No matter what you do, don’t use a hairdryer on your carpet. That can do some very bad damage to your carpet.
