They’re the easiest to clean because you can bleach them. People also associate them with looking clean and sanitary. If you want something that disguises stains, it’d end up looking like the upholstery on a subway or bus.

Hotels use white bed sheets exactly because they stain easily

With a white sheet it’s very easy to spot if they weren’t cleaned properly.

Having the wash all the same color also makes it easier because you don’t worry about bleeding colors and fading, and you can use bleach to clean them and remove stains.

They clean-looking, bleachable, easy to buy in bulk, and there’s a flip side to what you mentioned: when they are dirty or stained with weird substances, that is *easy to see.*

It’s to show off that they are clean and unstained.

Would you want to sleep in a hotel bed covered in wacky patterns like the floor of funhaven, so you can’t tell if it’s ever been cleaned?

On top of practicality, for a long time bed sheets only came in white. That is part of why people would embroider on them so they looked less plain. That is why the January sales of bed linens are called White Sales

Yes and no. White shows stains more than colors, but colors are not harder to stain. You just see it less.

On the other hand, if you want to get rid of stains, treatment with things like lots of chlorine bleach and similar chemicals can take out almost anything. Unfortunately, that almost anything includes any colors in your sheets that are supposed to be there.

Additionally, those same caustic chemicals will kill most bacteria, mold, and mildew, so the next person to use those sheets is protected from whatever nastiness the last customer might have gotten on those sheets.

I also suspect that some customers might be suspicious of colored sheets on the grounds that it is harder to see the stains. With white sheets, a glance can tell you the sheets are clean.

Because if a white sheet ain’t white, you know it’s dirty.

The exact reason we don’t make car interiors out of white fabric.

Bleach. You just use bleach. Kills most stains, stuff is back to white. Try that on dark fabric and its ruined.

You can also check easily if something is dirty. Helps clients feel safe, makes housekeeping aware of nastyness.

Exactly because of this… Every stain can be easily seen, so it looks clean and you can be sure hotel staff washed it.

Harsh chemicals can be used on white sheets to bleach away the stains. A lot more care has to be used in cleaning other colored sheets.
