Baby dribble may look clear — but that doesn't necessarily mean it will always dry clear on fabric!

Our Bibbilyboo waterproof dribble bibs are made with a super-absorbent cotton-rich top layer designed to draw moisture away from your baby's clothes, with a soft waterproof backing underneath.

And because that top layer is doing a lot of absorbing, it can occasionally develop stains or colour changes during use.

You might notice yellow or orange patches, pink or reddish marks, darker areas or even patches that look lighter than the surrounding fabric.

So what's causing them — and can you get rid of them?

💧 What's Actually Going Onto a Dribble Bib?

Although we usually just call it "dribble", a bib worn throughout the day can come into contact with much more than saliva.

This can include:

• Saliva
• Milk residue
• Reflux or spit-up
• Tiny traces of food
• Skin creams and lotions
• Natural oils from the skin
• Microorganisms naturally present on the skin and in the mouth

Once these substances are absorbed into fabric, they can leave behind residues or interact with the fibres and dyes.

That's why a bib can be perfectly clean and its original colour when new, but gradually develop staining during wear.

🩷 Why Has My Bib Turned Pink?

This is probably the strangest one — and understandably it can be alarming when a pink or reddish patch suddenly appears on a bib!

Pink staining doesn't necessarily mean that pink dye has somehow appeared in the fabric.

One possible cause of unusual pink or reddish staining on textiles is pigment-producing microorganisms.

Certain naturally occurring bacteria can produce coloured pigments under the right conditions. Moisture, temperature and pH can all influence pigment production, and some bacteria are known to produce pink or red pigmentation.

A frequently discussed example is Serratia marcescens, which can produce a pink/red pigment and has been documented causing pink staining on fabrics.

That does not mean that every pink bib stain is caused by bacteria, and it's impossible to identify the cause of an individual stain from colour alone. Food, milk, skincare products, dyes and other residues can produce similar marks.

If you're repeatedly seeing unexplained pink or red staining on items that come into contact with your baby's mouth or milk — particularly bottles, feeding equipment or expressed breast milk — speak to your healthcare professional for advice rather than assuming it's simply a fabric stain.

💛 What About Yellow or Orange Dribble Stains?

Yellowish staining is much more familiar to most parents.

Saliva and other bodily fluids contain proteins and other organic compounds. Add in tiny amounts of milk, reflux, food or skincare products and those residues can become much more noticeable once they have dried.

A bib can therefore develop a yellow, cream, orange or brownish mark even though the moisture that originally went onto it looked completely clear.

Leaving a heavily saturated bib damp for long periods can make staining more difficult to remove, so regular changes during particularly dribbly days can help.

🤍 Why Does a Patch Sometimes Look Bleached or Lighter?

Not every colour change is actually a "stain".

Sometimes repeated exposure to moisture, washing products, skincare ingredients, food, sunlight or other substances can affect the appearance of a coloured textile itself.

This can create an area that looks lighter, faded or bleached rather than leaving a darker mark on top of the fabric.

Unfortunately, if the actual dye in a fabric has been permanently altered rather than something being deposited onto the fibres, stain removal won't restore that colour.

This is also why we recommend avoiding chlorine bleach and harsh stain-removing products on your Bibbilyboo bibs.

🍼 Dribble Bibs vs Feeding Bibs

Our dribble bibs are designed primarily for:

• Everyday dribbling and drooling
• Teething stages
• Light reflux and spit-up
• Keeping clothing underneath dry

They're not designed as feeding bibs for bottles, breastfeeds or weaning meals.

Milk, formula and brightly coloured foods can create much tougher stains, particularly on a soft absorbent textile.

For meals and weaning, our full-coverage waterproof feeding bibs are a much better option.

🫧 How to Treat a Fresh Dribble or Milk Stain

The sooner you tackle an organic stain, the better your chances of removing it.

1. Rinse promptly

If you notice a heavily soiled area, rinse it in cool water rather than allowing the residue to dry into the fibres.

2. Wash according to the care instructions

Wash your bib with your normal suitable detergent following the temperature and care instructions on the product.

Avoid chlorine bleach and aggressive stain treatments, which can damage the fabric, alter its colour or affect the waterproof components.

3. Don't apply high heat to a stain you're trying to remove

If a stain is still visible after washing, avoid repeatedly exposing it to high temperatures while you're trying to treat it.

4. Try natural sunlight

One of our favourite tricks for stubborn organic baby stains is wonderfully simple: sunshine!

After washing, leave the damp bib in natural daylight.

Sunlight can help break down some of the compounds responsible for organic staining and can be particularly effective on yellowish milk, food, reflux and dribble marks.

You may need to repeat the wash-and-sunlight process for a stubborn stain.

🌞 The Sunlight Trick Works on Other Baby Laundry Too

It's worth trying on:

• Muslins
• Sleepsuits and vests
• Cot sheets
• Reusable nappies
• Feeding bibs
• Those spectacular baby poo explosions every parent eventually encounters!

🧺 How Can I Help Prevent Staining?

A few simple habits can make a big difference:

• Change saturated bibs regularly. Don't leave the same very wet bib against the skin all day.
• Rinse obvious marks promptly where possible.
• Don't leave damp, used bibs screwed up in a bag or laundry basket for days.
• Use a feeding bib at mealtimes to protect your dribble bibs from stronger food and milk stains.
• Follow the washing instructions and avoid harsh bleaching products.
• Rotate your bibs during particularly dribbly stages so each one has time to be properly washed and dried.

💙 Does Staining Mean My Bib Has Stopped Working?

Usually, no.

A surface stain doesn't automatically mean there's anything wrong with the waterproof backing or absorbency of your Bibbilyboo bib.

These bibs have a tough job: they're sitting right underneath a very dribbly little mouth and absorbing moisture that would otherwise be soaking into your baby's clothes.

Some evidence of that hard work can occasionally remain behind!
