TL;DR
Personal care items collect a mix that ordinary household cleaning never meets: skin oil, product residue, keratin and moisture. That combination forms biofilm, a sticky bacterial layer that surface wiping leaves behind. The fix is nearly always the same shape -- soak in warm soapy water, agitate with a small brush, rinse thoroughly, and dry completely before storing.
Why Personal Items Get Dirty Differently
Household dust is mostly fibers, skin flakes and outdoor grit that sits loosely on a surface. Personal items collect something stickier.
Every day, a hairbrush picks up sebum from the scalp along with whatever styling product went on that morning. A makeup sponge absorbs oil-based product and holds it in a moist interior. A toothbrush holder catches drips that pool in a base with no drainage. In each case the soil is oily, warm and wet, which is the exact condition bacteria and mold need.
The result is biofilm. It is why a toothbrush holder feels slimy rather than dusty, and why a rinse alone never fixes it. Biofilm has to be physically broken with friction, which is why a small brush appears in almost every method below.
What Is the Universal Method for Cleaning Grooming Tools?
Soak the item in warm water with a small amount of gentle soap or shampoo for ten to fifteen minutes, agitate with a soft brush to break the film, rinse until the water runs clear, then dry completely with the bristles or opening facing down. Never store a damp grooming tool in a closed drawer.
The drying step is the one people skip, and it is the one that decides whether the item stays clean.
Hair Tools and Heat Tools
Brushes and combs need the loose hair pulled out first, since soaking hair-packed bristles just makes a wet mat. A comb or a pointed handle works well for lifting the layer out. After that, a soap soak clears the greasy film that makes a brush feel tacky.
Heat tools are different because they must never be submerged. A flat iron or curling wand carries baked-on product on the plates, and the safe method is unplugged, fully cool, with a barely damp cloth and gentle pressure. Hair dryers fail for a third reason entirely -- a clogged rear filter starves the motor of air and causes overheating, so that filter needs regular clearing.
Oral Care and Anything That Goes in Your Mouth
Retainers, mouthguards, denture cases and water flosser reservoirs share one rule: heat destroys them. Hot water and dishwashers warp thermoplastic appliances out of shape, and a warped retainer no longer fits.
Use cool or lukewarm water, a soft brush, and a cleaner intended for the appliance. Skip regular toothpaste on clear appliances, because its mild abrasives scratch the plastic and the scratches then hold stain and odor.
Anything that goes in the mouth also belongs to a dentist's care instructions rather than general cleaning advice, so follow the guidance that came with the appliance if it conflicts with anything here.

What About Coated Lenses and Soft Stones?
Two categories punish the wrong product hard. Eyeglass and sunglass lenses carry anti-reflective and scratch-resistant coatings that alcohol and ammonia degrade, which is why a glass cleaner leaves them hazy and streaky forever after. Warm water, a drop of dish soap, and a clean microfiber cloth is the correct method.
Soft gemstones and porous materials are the other. Pearls, opals, turquoise and coral are damaged by ultrasonic cleaners, acids and even prolonged water contact. Pearls in particular should be wiped with a damp cloth and never soaked.
How Often Should These Items Be Cleaned?
Cadence depends entirely on contact. Items that touch broken skin or the mouth need cleaning after each use. Items that touch clean skin and product can go weekly. Storage containers and holders need a monthly strip-down because they collect what drains off everything else.

FAQ
How often should you clean makeup brushes?
Brushes used with liquid or cream products benefit from weekly washing, since those formulas hold moisture and feed bacteria. Brushes used only with powder can go two to four weeks. Wash with gentle soap, rinse until clear, reshape the bristles, and dry flat with the head hanging over an edge.
Can you put personal care items in the dishwasher?
Generally no. Dishwasher heat warps thermoplastic retainers and mouthguards, loosens glued brush ferrules, and degrades silicone. Hard plastic holders and some non-electric tools may tolerate a top rack cycle, but hand washing with a small brush is safer and more thorough.
Why does my toothbrush holder get slimy?
Water runs down the brush handle and pools in the base, where it stays warm and undisturbed. That mixture of moisture, toothpaste residue and bacteria forms biofilm. The fix is a weekly wash with a bottle brush, a thorough rinse, and letting the holder dry fully before use.
What should never be used on eyeglass lenses?
Avoid ammonia-based glass cleaners, alcohol, acetone, and paper towels. All of them damage or scratch the anti-reflective coating on modern lenses. Use lukewarm water with a drop of dish soap and dry with a clean microfiber cloth kept free of grit.
Is it safe to clean jewelry in an ultrasonic cleaner?
Only for hard, solid stones like diamonds in secure settings, and only if the piece has no glued components. Pearls, opals, turquoise, emeralds and any treated or fracture-filled stone can be damaged. When in doubt, a soft brush with mild soapy water is the safer route.
How do you get rid of odor in a razor or shaver head?
Odor in a razor is usually trapped skin cells and soap scum. Rinse the head under hot running water after each use, tap out the water, and let it dry in open air rather than in a shower caddy. For electric shavers, follow the manufacturer's cleaning cycle instructions.
