Summer is the season of backyard barbecues, beach days, ball games, and popsicles on the porch. It's also the season of stains. The good news? Almost every classic summer stain comes out if you know what you're dealing with and act fast.


Here's your complete summer stain removal guide, organized by the culprits you're most likely to meet between Memorial Day and Labor Day.

The Golden Rules of Summer Stain Removal

Before we get into specific stains, four rules apply to nearly everything:

  1. Act fast. The longer a stain sits, the deeper it bonds with the fabric. Treat stains within hours, not days.
  2. Blot, don't rub. Rubbing pushes the stain deeper and spreads it wider. Always blot from the outside of the stain inward.
  3. Don't overload the washer. No matter what the stain is, a stuffed drum works against you. Clothes need room to move so water and detergent can flow through the fibers and flush the stain out. In an overloaded machine, pre-treated stains stay put and can even transfer to other items. For stained loads, fill the drum no more than three-quarters full.
  4. Skip the dryer until the stain is gone. Heat sets stains permanently. Air dry and re-treat if you can still see any trace.

Grass Stains

Grass stains are protein and chlorophyll working, which is why plain soap often isn't enough.


How to remove grass stains:

  1. Pre-treat with an enzyme-based stain remover or liquid laundry detergent rubbed directly into the stain. 
  2. Let it sit for 15 minutes. 
  3. Wash in the warmest water the fabric allows.


Pro Tip: For white fabrics, a soak in oxygen bleach can lift stubborn green residue. Avoid ammonia or degreasers, which can set the chlorophyll. 

Sweat and Deodorant Stains 

Those yellow underarm marks aren't just sweat, they're a chemical reaction between sweat and the aluminum in many antiperspirants. 


How to remove sweat stains:


  1. Make a paste of baking soda and water.
  2. Work it into the stain with your hands or soft brush.
  3. Let it sit for an hour before washing.
  4. For set-in yellowing on white shirts, soak in a mixture of hydrogen peroxide, baking soda, and water for 30 minutes.


Pro Tip: During the summer, wash sweaty clothes soon after wearing them. Letting them sit in a hamper accelerates yellowing and odor.

Sunscreen Stains  

Sunscreen protects your skin but can wreak havoc on fabric. The oils leave greasy marks, and a common ingredient, avobenzone, can react with minerals in hard water to leave rust-colored stains. 


How to remove sunscreen stains:


  1. Blot away excess sunscreen with a paper towel.
  2. Sprinkle cornstarch or baking soda on the spot to absorb the oil.
  3. After 30 minutes, brush off the cornstarch or baking soda.
  4. Apply liquid dish soap or a degreasing stain remover.
  5. Wash in warm water.


Pro Tip: Avoid using chlorine bleach on avobenzone stains. It can make the discoloration worse.

Ice Cream and Popsicle Stains   

Dairy stains are protein stains, and sugary popsicle drips consist mainly of dyes. 


How to remove ice cream stains: 


  1. Rinse with cold water first (hot water cooks the protein into the fabric).
  2. Pre-treat with enzyme detergent
  3. Wash as usual.


Pro Tip: For brightly dyed popsicle stains, follow up your cold water rinse and enzyme detergent wash with an oxygen bleach soak if color remains.

BBQ Sauce, Ketchup, and Mustard   

Condiment stains combine oil, sugar, and strong pigments. 


How to remove BBQ sauce and ketchup stains: 


  1. Scrape off any excess condiment.
  2. Flush the back of the stain with cold water
  3. Work in liquid detergent or dish soap.
  4. Rinse and repeat before washing.


Pro Tip: Mustard's turmeric pigment is especially stubborn. Treat it quickly and consider an oxygen bleach soak for whites.


Watermelon, Berry, and Fruit Juice Stains   

Fruit stains are tannin stains, and they set quickly in the sun.


How to remove fruit stains: 


  1. Flush immediately with cold water from the back of the fabric.
  2. Stretch the fabric over a clean bowl and carefully pour hot water through the stain from about a foot above (for durable fabrics only).
  3. Pre-treat any remainder and wash.

Sand, Dirt, and "Mystery Beach Grime"   

Fruit stains are tannin stains, and they set quickly in the sun.


How to handle it: 


  1. Let mud and sand dry completely.
  2. Shake or brush off as much of the dried dirt and sand as possible before washing.
  3. Pre-treat visible dirt marks with detergent before a normal wash.


Pro Tip: Though it can be timely, letting mud and sand dry completely before washing is an important step. Washing wet sand just grinds it into the fibers.


When to Call in the Professionals


Some summer stains are best left to the pros, especially on delicate fabrics, structured garments, or anything labeled "dry clean only." If you've treated a stain twice and it's still hanging on, stop before you damage the fabric. Professional cleaners have specialized solvents and techniques that can rescue garments home methods can't.
