Pickling is a method of preserving foods by fermenting them in an acidic liquid, called the pickling brine. This helps preserve the food by inhibiting bacterial growth. Pickling can impart unique flavors to foods that are quite different from the original fresh ingredients. However, one downside to pickling is that the acids in the pickling brine can cause stains on clothes, countertops and other surfaces. These pickling stains can be tricky to remove. With some effort and the right techniques though, you can get pickling stains out of fabric, wood, plastic, glass and other materials.

What Causes Pickling Stains?
The main culprit behind pickling stains is acetic acid, which is the main acid used for pickling. Acetic acid is a weak acid found in vinegar. Other acids like citric acid from lemon juice or lactic acid from fermentation may also be used for pickling and can cause stains.
When these acidic pickling liquids come into contact with fabrics, wood, plastic, glass and other surfaces, they can bond with the material. This causes discoloration and staining. The stains happen because the acids alter the chemical structure of the stained material.
Some common ways pickling stains can happen include:
- Spilling pickling brine while preparing pickled vegetables like pickles, relish, etc.
- Transferring pickled foods between jars and brine drips out.
- Eating pickled foods and accidental spills/splatters happen on clothes or countertops.
- Using equipment for pickling and the brine residue stains them.
- Pickling brine splashing out during the fermentation process.
- Touching pickled food and then touching a surface, transferring pickle juices.
The longer the pickled acid is left on a surface, the worse staining becomes. This is because the acid has more time to react with the material. So it’s important to treat pickling stains as soon as possible.
Removing Pickling Stains from Fabric
Pickling stains on fabric can appear as light yellow, brown or orange discoloration. The stained area may feel stiff or crunchy too. Follow these methods to remove pickling stains from clothes, tablecloths, towels and other fabric items:
Rinse With Cold Water
Rinsing the fabric with cold water can help dilute and flush away some of the staining acid. Do this as soon as possible after the stain happens. For best results, hold the fabric under cold running water or soak in cold water for 15-20 minutes. This helps stop the acid from fully setting into the fabric.
Baking Soda Paste
Making a thick paste of baking soda and water can help draw out pickle stains from fabric. Baking soda is a mild alkali which can neutralize and react with the acidic pickle stain.
Add 1-2 tablespoons of baking soda to just enough cold water to make a spreadable paste. Apply this paste over the stain generously. Let it sit for at least 15 minutes before rinsing. The baking soda paste may need to be reapplied and sit longer for tough set-in stains.
White Vinegar
Though vinegar is acidic, diluting it significantly lowers the acidity. A vinegar rinse can help remove pickling brine stains. Mix 1 part white vinegar with 3 parts cold water.
Soak the stained fabric in this vinegar solution for 30 minutes. Then rinse thoroughly with fresh water. Repeat if needed for stubborn stains. Don’t let fabrics sit in full strength vinegar as that could worsen staining.
Salt
Making a salt paste is another home remedy to lift pickle stains from fabric. The salt helps draw out and absorb the staining acids.
Mix 1 teaspoon salt with just enough warm water to form a thick paste. Rub this paste over the stain and let it dry completely. Rinse off the salty paste thoroughly. Repeat as needed.
Lemon Juice
Lemon juice contains citric acid, which can help remove pickle staining by reacting with the acids in the brine. Mix equal parts lemon juice and water. Apply it over the fabric stain.
After 30 minutes, rinse thoroughly with clean water. For tough stains, rub sliced lemon over it before rinsing. The vitamin C in lemons acts as a mild bleach to lighten stains.
Hydrogen Peroxide
Hydrogen peroxide is another mild bleach that can help lift pickled food stains. Mix 1 part 3% hydrogen peroxide with 2 parts water.
Spray this over the fabric stain. Let it bubble and fizz on the stain for 10-15 minutes. Then rinse thoroughly. Hydrogen peroxide works best on white fabrics. Use caution with colored fabrics as the peroxide can lighten the surrounding color too.
Laundry Detergent
For medium to heavy pickle stains that remain after trying other remedies, laundering with detergent may be required. Check the fabric care label instructions first.
Pre-treat the stain by rubbing a small amount of liquid laundry detergent or detergent paste directly on it. Let it sit briefly, then wash normally with detergent in the warmest water allowed for that fabric. Avoid using fabric softener as it can set in stains. Air dry in sunlight if possible to further lighten stains.
Bleach
If pickle stains on white clothes remain after washing with detergent, using bleach is an option. Check that the fabric is safe for bleaching first though.
Soak the fabric in a dilute bleach solution made with 1 part bleach and 4 parts cold water for up to 30 minutes before washing normally. Chlorine bleach works best for removing set-in stains on sturdy white fabrics. Be very cautious using bleach on colored fabrics as it can create white spots or alter the color.
Dry Cleaning
For delicate fabrics like silks, woolens, or fabrics where other methods are unsafe, take it for professional dry cleaning. The chemicals that dry cleaners use can help lift out set-in pickle stains without risking damage to the fabric.
Removing Pickling Stains from Wood
Spilled pickling brine can soak into wood surfaces like cutting boards, tables, floors and leave behind alkaline staining. Here are some simple methods to remove pickle stains from wood:
Baking Soda Paste
Just like with fabric, a baking soda paste helps draw pickle stains out of wood. Make a paste with 1-2 tablespoons baking soda and just enough water.
Rub it over the wood stain using a soft cloth or sponge. Let it sit for 10-15 minutes before rinsing clean. Baking soda is mildly abrasive so rub gently to avoid scuffing wood finishes.
Vinegar
Full strength white vinegar can help remove pickle discoloration from finished wood surfaces. Dip a sponge in white vinegar and wipe over the stained area. Allow the vinegar to penetrate for 5 minutes before wiping clean with a damp cloth.
Vinegar may damage some wood finishes like shellac though. Test vinegar on an inconspicuous spot first to check that it doesn’t strip or discolor the finish.
Hydrogen Peroxide
Hydrogen peroxide can lighten pickle stains on wood surfaces just like on fabrics. Mix 1 part 3% hydrogen peroxide with 2 parts water. Apply it over the stain with a sponge.
Let it fizz and lift the stain for 10 minutes before wiping clean with a damp rag. Be cautious using it on wood furniture with finishes as it can lighten surrounding areas too.
Oxalic Acid
For tougher wood staining, oxalic acid is an effective remover. It is a stronger acid that reacts with the staining acids.
Make a solution of 1 tablespoon oxalic acid powder dissolved in 1 cup warm water. Wear gloves when using oxalic acid as it is toxic. Use a sponge to apply it over the wood stain. Rinse thoroughly after 5 minutes.
Scrub with Salt
For light surface stains on unfinished wood, scrubbing with salt can help scour away the discoloration. The coarse grains provide gentle abrasion.
Sprinkle salt over the stained area and use half a lemon to rub the salt into the wood. The salt scrubs while the lemon juice bleaches. Rinse clean afterwards. Avoid using salt on finished wood as it could scratch the finish.
Sand and Refinish
If stains have penetrated deeply into unfinished wood, the only way to completely remove them is refinishing. Use medium grit sandpaper to sand away the top layer of stained wood fibers.
Wipe sanded wood with a cloth dampened in vinegar or hydrogen peroxide to lighten any remaining stains. Allow wood to fully dry before applying new sealant, stain or finish.
Removing Pickling Stains from Plastic
The porous, absorbent texture of plastic makes it prone to staining from pickled foods. Acidic pickle brine can bond with plastic to create yellowish, clouded marks. Here’s how to remove them:
Baking Soda and Vinegar
This classic combo of bases and acids can dissolve pickle stains on plastic. Make a paste with 2 tablespoons baking soda and 1 tablespoon water. Spread paste thickly over the stain. Let sit 5 minutes.
Sprinkle over a few tablespoons of white vinegar and let it foam and fizz on the paste for another 2-3 minutes. Wipe clean afterwards with a soft cloth and warm water.
Dish Soap
For light stains, rubbing with dish soap using a soft brush or sponge can help scrub them away. Apply a few drops of dish soap over the stain and scrub gently. Rinse clean afterwards.
The surfactants in dish soap help lift staining oils. Avoid abrasive scrubbing as it could scratch plastic surfaces.
Bleach
On white plastic surfaces like cutting boards or storage containers, bleach can lighten or remove pickle discoloration. Make a 10% bleach solution – 1 part bleach diluted with 9 parts water.
Wear gloves and apply it over the stain with a sponge or soft cloth. Let it sit briefly before rinsing. Be very cautious using bleach on colored plastic as it can alter the color.
Hydrogen Peroxide
Similar to its use on fabrics, hydrogen peroxide can naturally bleach plastic surfaces. Mix 1 part 3% hydrogen peroxide with 2 parts water.
Spray or wipe it over the stained area and allow to bubble for 5-10 minutes before rinsing. It works well on white plastics but test first on colored items to check for color change.
Isopropyl Alcohol
Rubbing alcohol contains isopropyl alcohol which can help dissolve staining on hard plastics like cutting boards, tupperware and more.
Dip a soft cloth in undiluted isopropyl alcohol and rub it over the stain. Allow it to penetrate for 2-3 minutes before rinsing clean. Don’t use alcohol on softer plastics as it could damage them.
WD-40
WD-40 also contains solvents that can break down residue staining on plastics. Spray or wipe it directly over the stain. Let it penetrate briefly before wiping clean with a soft rag.
WD-40 leaves an oily residue though so wash the plastic afterwards with dish soap and water. Avoid using it on plastics that come into contact with food.
Removing Pickling Stains from Glass
Glass jars, drinking glasses, windows and other glass items can all develop clouded, yellow stains when exposed to pickle brine. While etching can permanently damage glass, these methods can remove pickle stains from glass:
Baking Soda and Vinegar
As with plastic, baking soda combined with vinegar can help lift pickle stains off glass surfaces.
Make a paste of 2 tablespoons baking soda and 1 tablespoon water. Spread over the glass stain. After letting it sit briefly, spray white vinegar over the paste. Let fizz for 2-3 minutes before wiping clean.
Salt and Lemon
For light surface stains on glass, rubbing with salt and lemon can naturally scour them away. Sprinkle salt generously over the stained area. Use half a lemon to rub the salt into the glass.
The abrasive salt scrubs while the lemon juice bleaches. Rinse clean afterwards. Avoid using salt on decorative glazed glass as it could scratch the surface.
Hydrogen Peroxide
The bleaching properties of hydrogen peroxide can also lift stains off glass surfaces. Mix 1 part 3% hydrogen peroxide with 2 parts water.
Apply it over the stained area with a soft cloth. Let it sit 5-10 minutes, allowing it to bubble and lift the stain before rinsing clean.
Ammonia
For tougher stains, stronger alkalis like ammonia work well. Mix 1 tablespoon clear ammonia with 1 cup warm water.
Submerge any small glass items in the solution or wipe it over larger surfaces. Let it sit briefly before rinsing thoroughly with clean water afterwards. Use ammonia in a well-ventilated area.
How to Prevent Pickling Stains
While pickled foods are delicious, the brine can certainly cause annoying stains. Here are some tips to avoid pickling stains in the first place:
- Wear an apron or protective clothing when making and handling pickled items.
- Cover countertops with layers of newspaper or towels when bottling pickles.
- Work over a tray, pan or sink to contain spills.
- Transfer pickled foods between jars over a bowl to catch drips.
- Seal jars tightly and store properly to avoid leaks and spills.
- Clean up any pickling spills, splatters or drips immediately.
- Wash hands, clothes, and surfaces after handling pickled foods.
- Use plastic, stainless steel or glass containers instead of porous wood when fermenting foods.
- Choose finishes like polyurethane that resist staining for surfaces that will contact pickled foods.
Taking precautions when pickling and being diligent about cleaning can help minimize the chance of permanent staining. But even with the best efforts, mishaps can happen. Using the stain removal methods outlined above though, you can successfully get out pickling stains!
