Several readers have asked how to get those difficult stains out of their favourite pair of grey sweat pants.

We all know how much we love our comfy sweats so I’ve written a simple step-by-step guide on how to remove those stubborn stains from your sweatpants without damaging the fabric or making them unwearable.

All you need is a few common household ingredients!

This technique works well on everything from workout clothes to fancy dinner wear. It’s even gentle enough for delicate fabrics like silk!

In addition, this recipe is safe for almost all washable fabrics. The ingredients are inexpensive and kept in most home pantries. It’s also simple enough for any homeowner to complete in less than an hour.

Steps To Get Stains Out Of Grey Sweat Pants

Step 1: Hit the Dollar Store (or similar) for cleaning supplies Next, you’ll want to hit up your local dollar store or big-box discount retailer and pick up the ingredients listed below.

This is where you find good prices on quality products because they are marketed directly to consumers. The bottles I linked here will do just fine if you don’t have access to a dollar store but these items are often available at even lower costs at warehouse clubs like Sam’s Club or Costco.

Don’t forget that many of these grocery stores sell generic brands which can be just as good as name brands!

One gallon of distilled white vinegar, $1 Two or three-gallon bucket, $3/5 One box of Borax, $4 One-gallon rubbing alcohol (80% isopropyl), $2 Medium to large tub with a water spigot, free from your sink.

Step 2: In a container big enough to hold the sweatpants and one gallon of white vinegar, mix 1.5 cups of distilled white vinegar with 4 cups of hot water

The vinegar will form a mixture that is thinner than the original volume of liquid.

This is because some of the water has been used to carry non-polar molecules into the vinegar which are then separated from polar molecules by phase equilibrium.

Phase equilibrium describes how polar and non-polar molecules interact when mixed together in different proportions.

Step 3: Soak Sweatpants in Vinegar Solution After you’ve made your solution, it’s time to get your sweatpants nice and wet!

Fill up your tub with enough hot water to cover your pants completely. As you pour in the hot water, add in one cup of vinegar for every five gallons of water.

Step 4: Add Borax Once the pants are in the tub, go ahead and add in a few scoops of borax powder.

Borax is a naturally occurring mineral typically mined in the USA and used here in laundry detergents and in cleaning solutions like this one!

Again, you want to use around 1 to 2 cups per five gallons of water. This gives our mix just enough cleaning power without making it overly harsh for delicate fabrics.

Step 5: Let it Sit Give your pants time to soak for at least an hour or until they are soft and pliable again. If these stains were old or especially stubborn then you’ll want to let them sit overnight instead.

But don’t leave them soaking for longer than 12 hours because the natural properties of vinegar can damage fabrics.

Step 6: Rinse and Dry Once your pants have soaked for a while, take them out of the tub and rinse thoroughly with cold water.

I left mine in a tub outside to air dry overnight but you can also use the spin cycle on your washing machine to get things moving along quickly. In both cases, be sure that no clothing items are sitting directly against each other as they will become stained from residual vinegar residue.

Conclusion

In short, one gallon of distilled white vinegar will clean between 3-5 loads of laundry depending on how much you’re cleaning at once.

Vinegar is naturally anti-bacterial which means it’s able to kill something like 99% of bacteria that gets into the fabric!

This makes it great for washing workout clothes or any other garments that regularly get soaked with sweat during use.

The best part is that you can do this same process over and over again without damaging the fabric because vinegar only works to remove dirt!

Happy laundering!
