How to Clean Sticky, Stained Old Tupperware and Restore to Like-New Condition

Hey there! If you‘re anything like me, you‘ve probably come across some old Tupperware containers in your cabinets that have gotten dingy, stained, or downright sticky over the years. I totally get the struggle – no one wants to throw away perfectly usable stuff, but cleaning gunky plastic ware is no fun either.

Well, you‘ve come to the right place! After trial and error with all sorts of techniques, I‘ve whipped up the ultimate guide to cleaning antique Tupperware and bringing it back to life. Armed with the right methods and a little elbow grease, even the grimmest 1970s Tupperware can become bright and shiny once again.

I‘ll walk you through:

• Assessing if old containers are safe for reuse
• The most effective cleaning solutions for tackling stickiness
• Vintage Tupperware value and collectability
• Steps to make cleaned pieces last for years to come

Let‘s dig in!

Step 1: Is It Safe to Use Old Plastic Ware?

Before attempting to clean up an old Tupperware container, first check that it‘s still in good enough condition to reuse, especially for food storage. Here are the main safety factors to look for:

Age: In general, Tupperware less than 10 years old is likely still perfectly safe to use if in good shape. Once you get over 10-15 years, take a closer inspection before reuse.

Appearance: Check all surfaces for cracks, chips, odd textures, and deterioration. Immediately discard any containers with damage.

Smell Test: Give the Tupperware a sniff check. If you detect chemical or artificial odors, it‘s a red flag the plastic may be breaking down.

Labels: Scan for any indication the product is BPA-free, especially if vintage. BPA is a chemical used in some older plastics that can leach out over time.

Changes in Texture: If the plastic feels sticky, gummy, or oily, it could be degrading and time to let it go. Brittle plastic is also a bad sign.

My rule of thumb is Tupperware under 10 years old that passes the appearance and smell test is likely fine for reuse. Anything older or showing wear should be examined closely or replaced to be safe. Don‘t risk your health – when in doubt, throw it out!

Step 2: How to Clean Sticky, Gummy Plasticware

If your Tupperware checks out for reuse, let‘s focus on getting it squeaky clean! Here are my top tricks for tackling sticky grime:

Baking Soda and Vinegar Paste

One of the best grease-cutting solutions is making a paste of baking soda and vinegar. Here‘s how it works:

1. Add 1 cup baking soda to the Tupperware, coating the interior.
2. Pour in 1/4 to 1/2 cup vinegar and quickly stir into a thick paste.
3. Apply paste over any sticky areas and let sit for 30 minutes minimum.
4. Use a soft brush or sponge to gently scrub residue away.
5. Rinse very thoroughly with warm water – vinegar can leave an odor if not washed out completely.

The chemical reaction between the baking soda and vinegar loosens years of stuck-on gunk. I like to use this method first when reviving an old container, before trying harsher cleaners.

Dish Soap and Warm Water Soak

For food and grease-related stickiness, a warm soapy soak can work wonders:

1. Fill container with warm water and add a few squirts of regular dish soap.
2. Allow to soak 1-2 hours so the soap permeates sticky buildup.
3. Scrub with a soft brush or sponge, starting gentle and increasing pressure for stubborn areas.
4. Rinse thoroughly and air dry.

The warm water helps dissolve residue while the soap tackles oily grime. For tough stains, repeat and extend the soaking time. This inexpensive method usually does the trick!

Rubbing Alcohol or Hydrogen Peroxide

For super tenacious sticky spots, break out the big guns – alcohol and peroxide. Here‘s how to use them:

1. Fill container with enough rubbing alcohol or hydrogen peroxide to coat the interior.
2. Allow to soak 15-30 minutes so the chemicals can penetrate and break down oils.
3. Scrub with a soft brush. Apply light pressure only.
4. Rinse very thoroughly – residual alcohol or peroxide can be harmful.

Thanks to their solvent properties, these strong chemicals can conquer almost any sticky mess. But use sparingly and open windows since fumes can be strong!

Step 3: Removing Stains from Plastic Containers

Now let‘s tackle ugly stains that can mar the look of vintage Tupperware. Here are my top stain-busting methods:

Baking Soda or Lemon Juice Scrub

For light stains, a baking soda paste works wonders. Just mix baking soda and water into a thick paste, then apply and let sit overnight before scrubbing clean. The gritty texture lifts stains without heavy chemicals.

Lemon juice mixed with baking soda or salt forms a gentle abrasive scrub. The acid lifts stains while the other ingredients provide scrubbing power.

Vinegar or Hydrogen Peroxide Soak

To loosen set-in stains, try soaking the container in undiluted vinegar or hydrogen peroxide 1-2 hours. Afterwards, scrub with baking soda paste and rinse. The acids in these common cleaners break down staining compounds.

Sunlight

Believe it or not, the sun‘s UV rays can actually bleach away some plastic stains. Place a lemon slice or two in the container to provide acid, then set outside in direct full sunlight 2-3 days. Just bring indoors daily to avoid outdoor grime buildup.

Mr. Clean Magic Eraser

These magical cleaning wipes use melamine foam that functions as a mild abrasive when wet. Gently rub stained areas when damp to lift discoloration. Take care not to rub too hard on vintage plastic.

Bleach or Ammonia (Use Caution!)

Heavy duty cleaners like diluted bleach, ammonia, or automatic dishwasher detergent can tackle robust stains BUT exercise caution. Start with very diluted solutions and limit contact time to avoid possible damage to plastic. Never mix bleach and ammonia.

With some trials, you‘ll find the right stain-fighting method that restores your Tupperware without harming it. Personally, I stick to gentler solutions whenever possible.

Step 4: Removing Odors from Stinky Old Plasticware

Musty vintage Tupperware smells can definitely put a damper on reuse. Here‘s how to freshen up malodorous containers:

• Baking soda: Sprinkle interior generously and leave overnight before rinsing. Baking soda absorbs funky odors like a charm.
• Vinegar: Fill with undiluted vinegar and allow to soak 1-2 hours before scrubbing and rinsing well. Vinegar kills mildew and bacteria causing smells.
• Air and sunlight: Allow container to air out in sunlight 2-3 days – the UV rays and fresh air help deodorize.
• Hydrogen peroxide: Fill container with peroxide diluted with water at a 1:1 ratio. Let soak overnight before rinsing thoroughly. Attacks stinky grime on a chemical level.
• Activated charcoal: Place charcoal inside container overnight. It adsorbs stagnant odors like magic!

With some experimentation, you‘ll discover the right odor elimination method for your stinky Tupperware. Say goodbye to musty smells!

Step 5: Sanitizing Germy Vintage Containers

Before reusing vintage Tupperware for food, be sure to fully sanitize to destroy possible mold, fungi, and bacteria. Here are safe sanitizing solutions:

• Vinegar: Mix one part vinegar with 3 parts water and wipe/soak container interior. Rinse thoroughly. Vinegar is antibacterial and antifungal.
• Hydrogen peroxide: Use 3% concentration diluted 1:1 with water. Soak container for 2-3 minutes before rinsing to kill germs.
• Boiling water: Fill container with boiling water and let sit 5-10 minutes. Dump out water completely afterwards. Heat kills microorganisms.
• Dishwasher: Run vintage Tupperware through a full heated dishwasher cycle. Use dry setting, not just rinse, so interior reaches sanitizing temperatures.

Once cleaned and sanitized, old Tupperware can safely store all kinds of foods again while looking fabulous!

Step 6: Does Old Tupperware Contain BPA?

What about worries over BPA in vintage plastic ware? Here‘s a quick lowdown:

• Tupperware originally used BPA in their plastic products up until 2010.
• Containers labeled "Tupperware" produced after 2010 are guaranteed BPA-free.
• Heating and wear can increase BPA leaching from older containers over time.
• Consider replacing Tupperware over 10-15 years old with new BPA-free versions to be safe.

While small exposures from old Tupperware are unlikely to pose big risks, women who are pregnant, nursing, or have hormone issues should take extra care.

When unsure, I suggest investing in new BPA-free storage alternatives for worry-free food use. Better safe than sorry!

Step 7: Determining If Vintage Tupperware Is Valuable

Cleaning up vintage Tupperware often uncovers hidden gems! While most old containers are everyday pieces, certain rare finds can be quite valuable to collectors. Here are top factors that increase collectable value:

• Rarity: Hard-to-find colors, patterns, and special editions are most prized. Research your piece to assess rarity.
• Condition: Items in like-new, pristine condition bring big bucks. Signs of use and wear tank value.
• Desirability: Iconic, vintage designs like the 1950s Wonderlier Bowl are hot items among collectors.
• Age: Very old pieces from the late 1940s/early 1950s fetch the highest prices.
• Original Parts: All original components (lid, accessories, labels) boost collectability significantly.

I always research any cool vintage pieces using online price guides before considering selling. With the right rare find, you could make some serious cash!

Step 8: Storing Tupperware Properly for Years of Use

Once that vintage Tupperware gleams like new, be sure to store it correctly so it stays that way:

• Keep away from direct sun, heat sources, and temperature extremes to prevent warping.
• Wash gently by hand with mild detergent and avoid abrasive scrubbers.
• Rinse extremely thoroughly after washing to prevent soap residue buildup.
• Allow to air dry fully before storage to prevent mildew growth.
• Separate stacked items with lining to prevent scratching.
• Store in a cool, dry cupboard away from chemicals, heat, and sunlight.

With proper care, quality Tupperware can serve duty for decades. But improper storage can quickly degrade plastic and necessitate early retirement.

Step 9: When to Toss Unsalvageable Vintage Pieces

Although cleaning methods can rejuvenate most Tupperware, severely damaged vintage pieces should get tossed. Here are signs it‘s time to say goodbye:

• Deep cracking, pitting, cloudiness or heavy scratching.
• Permanent stains that even heavy duty cleaners can‘t tackle.
• Warping that prevents lids from sealing tightly.
• Brittleness, marked discoloration, or strange chemical smells.
• Gummy, sticky texture indicating plastic breakdown.
• No BPA-free labeling on older containers.

Retire any Tupperware showing multiple signs of aging. Don‘t risk your health trying to salvage damaged vintage plasticware. Some stains and flaws simply can‘t be fixed.

Step 10: Making the Switch to Glass Storage Containers

If vintage plastic gives you pause, switching to glass Tupperware is a smart solution:

• Seek out food-grade soda-lime or borosilicate glass options.
• Pick thermal shock resistant types to prevent breakage.
• Ensure any lids are BPA-free with air-tight seals.
• Opt for silicone sleeves to avoid shattered glass.
• Take care handling due to fragility. Avoid freezing or microwaving.

While glass breaks easier, it offers an eco-friendly, non-porous storage solution free of chemicals and leaching worries. Just handle glassware gently and you‘re good to go!
