How to wash a VOYJOY seamless knit so it keeps its recovery
A stretch knit is only as good as its spandex, and heat is what tires spandex. Pads out, cold water, no fabric softener, flat or line dry: why each step is there, what happens when you skip one, and what the label sewn into the piece is allowed to tell you.
A seamless knit has one job that matters more than any other, and it is not stretching. It is coming back. The spandex in a VOYJOY short stretches to several times its length every time you sit, and the reason the band is where you left it at the end of a session is that the fibre returned every one of those times. A knit that has stopped returning is a knit that has been worn out, and most of the wearing out happens in the machine, not in the gym.
So the wash is not care in the sense of fuss. It is the part of ownership that decides how long the piece stays the piece you bought, and every step below exists to keep heat and coating away from the spandex. The label sewn into the garment is the document that governs; the steps below are the reasons behind what it says.
Pads out first
Every VOYJOY bra and every padded tank carries a removable pad in each cup, and it lifts out through the opening on the inside of the cup and goes back the same way. Take them out before the piece goes anywhere near water. A pad washed inside a cup folds, and a folded pad dries into its fold; a pad washed on its own lies flat, dries in half the time and goes back the shape it came out.
Two smaller things while the pads are out. Turn the bra inside out, so the band and the straps take the rubbing rather than the face of the knit. And if it is one of the two bandeaus, the silicone strip inside the band wants nothing but water and the mildest detergent: softener on silicone is the fastest way to lose the grip that holds a strapless bra up.
Cold water, and why the temperature matters more than the detergent
Heat tires spandex. Not in one wash, and not so you would see it that day, but a hot cycle relaxes the fibre a little more each time, and the band that used to settle by the end of a warm-up starts settling before you leave the house. Cold water washes a knit worn for an hour perfectly well, because what is on it is sweat and skin, not mud, and both come out at any temperature.
The detergent matters less than people think, so long as it is a plain one. Skip anything that promises softness, brightness or fragrance that lasts, all of which are coatings. And keep the load light: a seamless knit tangled round a towel for forty minutes is being stretched for forty minutes with no chance to return.
Skip the softener
Fabric softener works by leaving a film on fibre, and a film on spandex is the one thing the fibre cannot work through. A knit that has been softened a few times feels softer and holds less, which is exactly the trade nobody wants in a short. The same goes for dryer sheets, which do the same job with heat added.
If the knit feels stiff after a cold wash, it is dry detergent, not a fault in the cloth. An extra rinse takes it out. Softness in a seamless knit comes from the fibre and the knitting, and both are still there under the residue.
Flat or line, not the hot tumble
A tumble dryer on hot is the single hardest thing a stretch knit goes through, and it is where most tired bands come from. Lay the piece flat on a towel or hang it from the band, out of direct sun, and it is dry in an evening; there is very little water in a knit this thin to begin with. A bra dries flat with its cups shaped and its pads beside it.
If the label sewn into a piece allows a machine dry, it allows it at low, and the label is the document that decides. What no label allows is the hot cycle, and the reason is the one this whole piece keeps coming back to: the fibre that returns is the fibre that heat relaxes.

The ribbed bandeau: a silicone strip inside the band does the holding, and it wants water and a mild detergent, never softener.

What the label sewn into the piece is allowed to say
A care label in the United States is written under the Care Labeling Rule, and the Federal Trade Commission's guide to it sets out five things a washing instruction must address.
| What the label says | What the rule requires of it |
|---|---|
| Hand or machine, and a temperature | The temperature must appear if hot water would damage the piece |
| Bleach | Stated as safe, non-chlorine only, or none |
| How to dry | A temperature only "if regular use of high temperature will harm the product" |
| Whether to iron | Only "if a product needs repeated ironing" |
| "Do not", "No", "Only" | A warning against any procedure a buyer might assume is safe and is not |
The maker must hold "reliable evidence to support the care instructions", and the label must stay "permanently and securely" attached and "legible during the useful life of the product". That last phrase is why the label is knitted or sewn into the band rather than hung on a card, and why it is the document to follow when a page here and the label in your hands disagree.
When a knit is simply worn out
Two signs, and neither is fixed by a wash. A band that has stretched over the day and does not come back the next morning is a knit whose spandex is tired; a band that felt tight in the first minute and settled by the end of a warm-up was the right letter doing its job, and the two are easy to tell apart after a night on a chair. The second sign is a seat that has gone thin where it stretched most, which no wash restores.
How long that takes depends on the wash as much as on the knit, which is why no card on this site promises a count of washes or of seasons. Cold, plain, flat, and the pads out first: that is the whole of what we can tell you, and it is most of what the label says too.
The spandex that stretches is the spandex that returns. Everything in the wash is about keeping heat off it.
