The part of a coin laundry trip that decides its length happens at home, before anything is carried out to a car. Sorting is not a tidiness habit. It is the step that turns a vague pile into a known number of machine sized loads, and knowing that number before you leave is the difference between a short visit and a long one.

Why the sort happens at home and not at the coin laundry
A heap of laundry at home is an unknown quantity. The same heap sorted is a list, and the list reads something like three loads, one of them heavy.
That list is what every other decision rests on. How many machines you need, which drum sizes, how much detergent to bring, and roughly how long the whole visit will run.
Doing the sort at a coin laundry is possible and it is the slowest available way to do it. You are working standing up, on a folding surface, in a room shared with other people, with nowhere to put the piles down while you make them.
The work is identical either way. The only question is whether it happens before the trip or during it, and doing it during it stretches a coin laundry visit by half an hour without a single thing being washed any better.
Colour is the first cut and not the last one
Everyone sorts by colour first, because it is the one laundry rule almost everybody was taught, and it is real enough. Dye moves in warm water, and new or deep colours move most.
Three groups cover it for most households. Whites and near whites. Mid colours, which is most of a wardrobe. Darks, meaning navy, black, deep red and anything strongly coloured.
Anything new gets kept apart for its first two or three washes whichever group it belongs to, because that is when almost all dye transfer happens and it never happens twice.
Colour on its own, though, produces poor loads. A colour only sort will put a bath towel, a pair of work jeans and a thin summer shirt in one drum because they happen to be the same shade, and those three things want different treatment in every other respect.
Fabric weight decides what shares a drum
Weight is the question that gets skipped, and it shows up at the dryer rather than at the washer.
Heavy means towels, jeans, sweatshirts, work trousers and bedding. These soak up a great deal of water, they give it back slowly, and they push lighter things around the drum with real force.
Light means shirts, underwear, thin synthetics, anything finely knitted and anything with a print or a fitted shape you want to keep.
A drum holding both runs until the heavy things are finished, which means the light things spend that entire extra stretch being worked and heated for no reason at all. That is where tired elastic and faded prints come from.
Split heavy from light inside each colour group, and you arrive at a coin laundry with loads that fit a machine instead of loads that merely fit a basket.
Soil level is the question people skip
The third cut is how dirty things actually are, and it makes the largest difference to what comes back out.
Start with the barely worn group. A shirt worn for one office day, a jumper worn over something else, things being washed because they were worn rather than because anything happened to them. These need very little.
Then the genuinely dirty group. Garden clothes, garage clothes, anything greasy, anything that came home carrying grit, sports kit after an actual game, kitchen cloths and pet bedding.
Putting that last group in with the first is how a clean shirt comes out with a grey cast to it. Soil that has been lifted off one garment has to go somewhere, and in a crowded drum a fair share of it settles back onto whatever else is in there.
Keeping the dirty group separate also lets you treat it properly, with a longer cycle and a full dose of detergent, without running the light group that way for no benefit.
Bagging by load so the sort survives the journey
A sort that gets tipped back into one basket at the front door was not a sort. It was tidying.
One bag for each load is the whole method, and the bags themselves do not matter. Laundry bags, pillowcases, supermarket carriers, a bin liner for the heavy group.
Each bag is one machine. That means you arrive at a coin laundry carrying machines rather than carrying laundry, and the loading takes two minutes instead of twenty.
Fill each bag to roughly the size of the load rather than to the top of the bag. A bag you cannot close easily is a load that will not tumble properly once it is in a drum.
The coin laundry on East Oak Street is set up for exactly this kind of load.
Pockets, zips and the two minutes before you leave
This check belongs at home for one plain reason, which is that home is where the bin is.
Go through every pocket on every garment. Tissues are the classic, and one of them will coat an entire load in white fragments that shaking does not remove. A pen is worse and it is usually final for whatever it touched.
Coins, keys, screws and small stones hammer around inside a drum for the whole cycle. They mark the drum, they chip enamel, and they are the ordinary reason a machine suddenly sounds wrong.
Zip every zip. An open zip is a small metal saw running against the rest of the load for thirty minutes, and it is the usual cause of a snagged knit that nobody can account for afterwards.
Fasten hooks, close velcro, and tie long straps and drawstrings loosely to themselves so they do not wrap around everything else in the drum.
Two minutes at home. The same job at a coin laundry is done standing over an open machine with the sorting already undone around your feet.
Common questions about coin laundry
Does sorting really change how long a coin laundry trip takes?
More than anything else within your control. Arriving with bagged loads means machines start filling within a couple of minutes, and loads matched by weight tend to finish together rather than straggling across the afternoon one at a time.
How many piles should I actually be making?
Most households settle on three or four. Colour gives the first cut, weight pulls the heavy things out, and soil level sets the dirty group aside. Past that you start making piles too small to be worth a machine of their own.
Is coin laundry still the right name when places take cards?
The term is older than the payment method and it has stuck as the general name for a self service laundry. Plenty of places now take cards, and people still use the older phrase for the type of place rather than for how anybody pays.
What if I genuinely cannot sort before I leave?
Then sort at the machines and accept the extra time. Even a rough split of heavy from light before anything is loaded is worth doing on its own, because that split is the one that decides how the drying goes.
Arriving at a coin laundry with one unsorted heap
It is worth spelling out what actually happens, because the cost of it is not obvious from the doorway.
You arrive, look for a surface, and tip everything out in a room where surfaces are the scarce thing. The sort takes longer than it would at home, partly because you are standing and partly because you are conscious of how much space it is taking up.
For that whole stretch, no machine is running. Sorting time gets added to the trip rather than absorbed by it.
Then the loads come out uneven, because sorting against a clock gives you piles that are roughly right rather than actually right. One machine goes in half empty and the next goes in packed to the door.
Then the dryers inherit all of it, and drying is the stage where a coin laundry trip either finishes cleanly or drags on. A mixed drum runs at the speed of the wettest heaviest item in it, and everything else sits in heat waiting.
None of this is a criticism of anyone standing at a folding table with an unsorted heap. It is simply the difference between doing the thinking at home, where it is free, and doing it at the machines, where it is not.
The Louisville part
Water here sits on the hard side, and that changes what you do at the sorting stage rather than anything you do once you reach a coin laundry. Mineral rich water blunts detergent, so the genuinely dirty group needs a full dose and a longer cycle, while the barely worn group needs less than most people give it. Overdosing a light load in hard water leaves residue behind in the fibre, and residue is what makes cotton feel stiff and look dull several months later.
Spring belongs in the soil sort too. The Ohio Valley runs a long and heavy pollen season, and anything worn in a garden or left hanging outside comes in carrying a fine yellow dust that transfers onto everything else in the drum. Through those weeks, outdoor clothes are worth their own bag rather than being mixed through a normal load.
Summer humidity acts on the pile before it ever reaches a machine. Damp sports kit or a wet bath towel left in a closed bag in July develops a smell within a day, and that smell is considerably harder to remove than the soil that was there first. Sort anything damp out the same afternoon and put it at the front of the queue.
Winter brings grit. Road salt and street grime collect on hems, cuffs and coat sleeves, and both are abrasive enough that they belong with the heavy dirty group rather than spread through an ordinary wash. Shaking a coat out over a doorstep before it goes in a bag removes a surprising amount of it, and what you shake out never has to be rinsed away later.
Where the sorted loads go
A sort done properly at home only pays off if the machines waiting at the other end are sized to the loads it produced.
The machines at our self-service laundry on East Oak Street hold enough water for a full heavy load to move freely from the first minute, so a bag sorted at home goes straight into a drum that fits it instead of being split apart at the door.
Our machines and the store are cleaned daily.
Our wash and fold service is there for the loads you would rather not stay for.
For general guidance, The American Cleaning Institute publishes a laundry basics guide that is a useful cross-check.
The short version
Sorting at home into machine sized piles is the one thing that makes a coin laundry trip short rather than long. Treat colour as the first cut, then split heavy from light, because weight is what decides how a load dries, then pull the genuinely dirty items aside so their soil does not settle back onto everything else. Bag each load separately so the sort survives the journey, and check pockets, zips and fastenings while you are still standing next to a bin. Arriving with bags that each equal one machine means loading takes minutes. Arriving with one heap means doing the same work standing up while nothing at all is washing.
