TL;DR
Rinse food off a bib before it dries and most of the work disappears. Cloth bibs wash by their care label with cool water first on protein stains, silicone bibs wash in warm soapy water with attention to the pocket fold, and both dry with the catch pocket open so nothing stays wet inside.
Rinse first, always
The single biggest factor in how a bib looks after six months is whether food gets rinsed off while it is still wet.
Hold the bib under cool running water right after the meal and let the bulk of the food go down the drain. Cool, not hot, because hot water sets protein stains from milk, egg, and meat.
For a silicone bib, that rinse is often the whole job. For a cloth bib, it prevents the stain from setting before laundry day.
Keep a small bin or hook near the sink so bibs get rinsed instead of piled.
Cloth bibs: wash by the label
Most cotton and terry bibs wash on a normal cycle with a mild detergent. Bibs with a waterproof backing or a laminated face need warm rather than hot water and a low or air dry, because heat cracks that backing.
Fasten hook-and-loop closures before washing. Open hook strips grab everything in the load and turn into lint magnets, and they wear out faster.
Skip fabric softener. It coats fibers, reduces absorbency, and holds odor, all of which are the opposite of what a bib is for.
Skip chlorine bleach too. It weakens fibers over time and often makes food stains on synthetic blends look worse, not better.
What removes food stains from bibs?
Rinse in cool water, then treat the stain with an enzyme laundry product for protein and food soils, letting it dwell as the label directs before washing warm. Sunlight after washing lightens many fruit and vegetable stains further. Hot water applied first sets the stain and makes it permanent.
Different stains behave differently. Milk, formula, egg, and meat are protein stains that need cool water and enzymes.
Fruit, vegetable, and juice stains are tannin or pigment stains, and they respond to an oxygen-based laundry booster and to sunlight.
Oil-based food, like avocado or butter, needs a little dish soap worked into the fabric first, because that is what breaks up the grease.
Carrot, tomato, and berry pigments may never come out fully. A clean stained bib is still a clean bib.
Silicone and plastic bibs
Wash a silicone bib in warm soapy water with a soft brush, or on the top rack of a dishwasher if the manufacturer says it is dishwasher safe.
The fold at the base of the catch pocket is where food hides. Open the pocket flat, brush the crease, and rinse the whole thing well.
Check any neck fastener, which is often a button-and-hole strip that collects residue at the edges.
Rinse thoroughly, since the bib touches a child's chin and hands constantly.
A white film on silicone is usually hard water minerals or detergent residue. A short soak in diluted white vinegar plus a thorough rinse clears it. Never combine vinegar with bleach.
Drying so nothing sours
Hang silicone bibs with the pocket open so water drains out, or lay them flat facing up. Water trapped in the pocket fold is the reason a bib develops a smell.
Air dry cloth bibs when they have a waterproof backing, and tumble dry on low otherwise. High heat is what cracks a backing and makes it useless.
Do not stack damp bibs in a drawer. That is how the whole stack ends up smelling.
Why does my bib smell even after washing?
A bib that still smells after washing usually has residue trapped somewhere the wash did not reach, such as the catch pocket fold, the hook-and-loop closure, or inside a laminated seam. It can also be detergent buildup in cloth. Rewash with an enzyme product, brush the folds, and dry the bib completely.
Detergent buildup is more common than people think. Too much soap does not rinse out, and the residue holds odor.
Try a wash with a normal dose and an extra rinse cycle. That alone fixes many mystery smells in baby laundry.

What to keep away from bibs
No bleach on silicone, since it degrades the material. No solvents or household disinfectants on anything that contacts a child's mouth.
Never mix bleach with ammonia or with an acid such as vinegar. Both combinations release toxic gas, and no bib job requires either.
Avoid abrasive scouring pads on silicone and plastic. Scratches hold residue.
Do not use fragrance-heavy products near a feeding item. Rinse well after any product you do use.
When to replace a bib
Replace a silicone bib that is torn, cracked at the pocket fold, sticky, or discolored in a way that survives a proper wash. Cracks hold residue you cannot reach.
Replace a cloth bib when the waterproof backing peels or cracks, when the fabric thins, or when a closure no longer holds.
Replace anything with a broken snap or a fraying tie, since loose small parts are a hazard.
Keeping the pile manageable
Rinse at the sink, wash cloth bibs with the regular baby laundry, and wash silicone bibs with the dishes. Splitting them by material makes the routine simpler than treating them as one category.

FAQ
Can silicone bibs go in the dishwasher?
Most can, on the top rack, if the manufacturer says so. Open the catch pocket so water reaches the fold, and place the bib where it will not fold over on itself. Hand washing in warm soapy water with a soft brush works just as well when you cannot confirm the bib is dishwasher safe.
How do you get carrot and tomato stains out of a bib?
Rinse in cool water immediately, treat with an oxygen-based laundry booster on cloth or a soapy scrub on silicone, then dry in sunlight, which lightens pigment stains noticeably. Carrot, tomato, and berry pigments often set permanently, especially in silicone, and a stained but clean bib is still perfectly usable.
Can you bleach baby bibs?
Skip chlorine bleach. It weakens cloth fibers over time, degrades silicone, and often makes food stains on synthetic blends look worse. Use an enzyme laundry product for protein stains and an oxygen-based booster for pigment stains instead, and never mix bleach with ammonia or with an acid.
How do you wash a bib with a waterproof backing?
Wash it warm, not hot, with a mild detergent, and dry on low heat or air only. Heat cracks the waterproof film, which is the part that actually protects clothing. Fasten hook-and-loop closures before washing, and skip fabric softener, which coats the fabric and holds odor.
Why do my baby's bibs smell sour?
Usually milk residue that was washed in warm or hot water, or detergent buildup that never rinsed out. Rewash with a normal detergent dose, an enzyme product, and an extra rinse. Check the catch pocket fold and closure strips, and dry the bib fully before storing it with others.
How often should bibs be washed?
Rinse after every meal and wash the same day for anything wet, greasy, or protein-based. Dry-crumb messes can wait a day. Damp bibs should never be stacked in a drawer, since one sour bib will make the whole stack smell within a day or two.
