Somewhere around month four, your silicone cup starts tasting faintly of dish soap. Or you chop a beetroot on the mat and it turns a shade of pink that doesn't rinse out. Either way you think: well, that's that, it's had a good run.
It hasn't had a good run. It's fine. Both problems are the same problem in different clothing, and both come out with a box of bicarb you already own.
Why silicone hangs onto things
Silicone loves oil. Not poetically. Chemically.
Fats, oils and the aromatic compounds in garlic, coffee and last night's curry cling to the surface instead of sliding off the way they do from glass. Detergent lifts most of it. What stays behind is a film, thin enough to be invisible and thick enough to taste.
That film is the smell. Your silicone hasn't gone off. It's wearing a jacket.
Stains run on the same mechanism. Turmeric pigment grabs the oily layer rather than the silicone underneath it. Take away the layer and the colour mostly leaves with it.
The normal wash, which covers most days
Dishwasher: top rack for anything you drink out of, either rack for Chop. That's the section. Ninety percent of your silicone will never need more than this.
By hand: warm water, normal dish soap, soft sponge, then rinse for longer than feels reasonable. Under-rinsing sits behind almost every "my cup tastes like soap" message we get. The fix is thirty extra seconds at the tap.
Air dry it. Silicone doesn't water spot, so you can walk off and leave it.
When it smells like something you ate
Warm water, a tablespoon of bicarb, thirty minutes, rinse well.
Bicarb is alkaline, which is exactly what breaks down the greasy film your detergent couldn't shift. Half an hour handles a normal offender.
For a cup that's taken an oat flat white every morning since March, give it an hour and rub a bicarb paste around the inside first.
White vinegar does a similar job at one part vinegar to four parts warm water. Pick one. Used together they cancel each other out and you've made expensive salty water.
When it's the colour of dinner

Beetroot. Turmeric. The tomato sauce that sat on Chop while you went looking for a container lid.
Mix bicarb with a splash of water until it's a paste, work it in with your fingers, leave it a minute, then run the piece through the dishwasher. Most colour goes on the first attempt. Anything stubborn needs a second.
Then there's the free option nobody mentions. Sunlight. Rinse the piece, leave it outside for an afternoon, and UV fades whatever's left.
It works on tomato especially well and costs nothing except remembering to bring it back in before dark.
Keep well away from it: bleach, oven cleaner, scouring pads, anything sold as a heavy duty degreaser.
These don't attack the stain, they attack the silicone. You'll trade an orange patch for a dull tacky one, and that swap is permanent.
What it handles, and where the edge sits

Flexible doesn't mean invincible. Here's the honest map.
Cold is a non-event. Iced coffee, spritzes, anything sitting over ice for three hours. Silicone doesn't sweat the way glass does, so your hand stays dry and the cup stays where you put it down.
Knives on Chop are the entire point of Chop. Use a normal slicing motion. Hack at the same two centimetres for a year and you'll score it, the same as any board.
Everything else, the drops and the kids and the outdoor table and being carried around a party by someone on their third drink, is what the material was built for.
Putting it away
No special shelf required. Stack cups inside each other. Chop lies flat, hangs on a hook, or rolls into a drawer without holding a crease.
One rule: dry first. Silicone won't grow mould, but two damp cups stacked in a closed cupboard for a week will come out smelling like the cupboard, and then you're back at the bicarb.
Questions we get
Is silicone dishwasher safe? Yes. Top rack for drinkware keeps it away from the heating element. Chop is happy on either.
Can it go in the microwave? Food-safe silicone, like STYLD., can.
Why does my cup taste like soap? You're rinsing it for about four seconds. Almost everyone is. Rinse it properly, and if the taste is still there, do the bicarb soak.
Does silicone leach anything into food? Premium food-safe silicone doesn't. Every STYLD.® piece is BPA, BPS and phthalate-free. The worry usually comes from cheap silicone padded out with plastic fillers, which is a different material sold under a borrowed name.
How long will it actually last? Years, with no real decline. It doesn't chip, crack or cloud, so there's no slow ugly middle age the way there is with plastic. When it finally goes, silicone recycles through specialist streams rather than your kerbside bin.
Can I use bleach? No. It eats the surface and leaves a dulled, slightly tacky finish that never comes back. Bicarb handles everything you were hoping bleach would.
