> Shiny patches on a flat or matte wall, in the shape of a scrub or a chair back, are burnishing. Sherwin-Williams and Benjamin Moore describe it as the sheen of the film going up where something rubbed, scrubbed or brushed against it. Flat paint in a hallway, on stairs, beside furniture and around light switches does this most. Abrasive cleaners and paints with little scrub resistance make it worse. You cannot wash the shine back to flat. Sherwin-Williams’ fix, once the spots are there, is to repaint, and to use a tougher sheen where the rubbing happens. Both companies say to wait at least two weeks before you wash new paint, and to clean with a soft sponge and a non-abrasive cleaner, then rinse.

## Burnishing, flashing, or something on the paint?

Sherwin-Williams defines marring, also called burnishing, as an unwanted increase in gloss where the paint was rubbed, scrubbed, or brushed by an object or a person. Benjamin Moore’s definition is the same event, and it adds that the sheen can go up or down. The usual places are the ones that get touched: family rooms, hallways, stairs and doors, plus the stripe a sofa or a chair leaves on a flat wall. It shows up after the paint has been lived with. It does not appear in the hour after you roll.

| | Burnishing | Flashing | Surfactant leaching |
| --- | --- | --- | --- |
| Looks like | A shiny path: beside furniture, at hand height, around a switch | A dull or shiny patch over a repair, or a stripe where the roller overlapped | Tan, brown or clear drips that look wet or sticky |
| When | After weeks of rubbing or washing | As the new coat dries | Days after painting, once moisture hits fresh latex |
| Does washing fix it? | No. More scrubbing polishes it further | No. The film thickness is uneven | Yes. Soap and water, or a hose outside |
| The real fix | Repaint the rubbed area in a sheen that can take the traffic | Repaint corner to corner, often after spot-priming patches | Wash it off. Do not paint over it |

Flashing is an application problem, covered in [flashing and lap marks](https://colorswatchlab.com/guides/paint-flashing-and-lap-marks/). Surfactant leaching is a residue on fresh latex, covered in [surfactant leaching](https://colorswatchlab.com/guides/surfactant-leaching/). If a damp cloth picks up a soapy film and the color under it matches the rest of the wall, you are in that third column, not this one.

## What polishes a flat wall

Both companies list the same four causes. Flat paint was used where people touch the wall, and a higher sheen would have been tougher. The wall gets washed often, especially with an abrasive cleaner. Furniture or other objects rub it. The paint itself has little resistance to scrubbing. Benjamin Moore names family rooms, hallways, stairs and doors as the rooms where this shows. Darker colors are not required for it to happen. Any flat film can take a polish. The ladder of sheens, and why flat hides flaws and also marks, is [the sheen guide](https://colorswatchlab.com/guides/paint-sheen-guide/).

The two companies do not name the identical replacement sheen, so this page does not collapse them into one rule. Sherwin-Williams tells you to choose semi-gloss or gloss rather than flat in high-traffic areas, and a durable formula on doors, window sills and trim. Benjamin Moore tells you to use eggshell, satin, pearl or semi-gloss in high-traffic areas, and to avoid flat there. Read that as a range, not a fight: both are saying the flat film is the one that burnishes, and the next sheen up is there because it can be cleaned with less damage. Room-by-room habits are in [sheen by room](https://colorswatchlab.com/guides/best-paint-sheen-by-room/).

## Cleaning without making a new shiny spot

If the shine is already there, more pressure will not dull it. It will widen it. Benjamin Moore’s cleaning instruction for preventing burnishing is a non-abrasive cleaner, a soft cloth or sponge, and a rinse with clean water. Sherwin-Williams says to check the paint maker’s cleaning instructions first, and to start with a soft sponge and water or a general-purpose household cleaner. Both say to wait at least two weeks after painting before that first wash, so the film can develop its washability. Another Benjamin Moore article on fresh paint is stricter and talks about 30 days. That disagreement, and the bottom-up washing method, is already worked out in [how to wash painted walls](https://colorswatchlab.com/guides/how-to-wash-painted-walls/). Follow the data sheet on your can when it names a time.

Sherwin-Williams does allow a stronger step for a stain that has penetrated: a careful abrasive cleaner and water, or household bleach diluted in water, then a rinse. That is a last try for a mark that will not move, not the weekly clean. Abrasive washing is also on their list of causes. If the stain is in the film, stop. The wash guide explains why a magic eraser and a glass cleaner are the wrong tools on paint.

## When the wall needs paint, not a sponge

Sherwin-Williams says that if the walls are already showing marring, the practical fix is to repaint, with a higher sheen and a more durable paint than the flat that polished. Moving the furniture off the wall is the prevention they pair with that. Benjamin Moore’s page is aimed at not creating the next spot: notice where things rub, clean gently, wait two weeks, and do not put flat paint in the traffic path.

Editorial reading of those two pages: a small dab of the original flat paint on a polished streak often still shows, because the worn film is glossier than the paint in the can. If the shine is a long path, plan on the whole wall from corner to corner, the same way a flashing touch-up often has to be. That corner-to-corner habit is in [flashing and lap marks](https://colorswatchlab.com/guides/paint-flashing-and-lap-marks/).

- Pull furniture far enough that it does not rest on a flat wall. Sherwin-Williams says to rearrange it. Benjamin Moore says to note the contact points.

- In a hallway, on stairs and behind dining chairs, pick a sheen from the range above, not flat, the next time you paint.

- Doors, sills and trim already want a durable sheen. Burning them shiny with a scouring pad is the same mechanism as the wall.

- Give new paint the wait on the can before anyone cleans it. Two weeks is the number both burnishing pages print. Cure, as distinct from dry-to-touch, is [dry time versus cure time](https://colorswatchlab.com/guides/paint-dry-time-vs-cure-time/).


## FAQ

### Why is my flat wall shiny where I wash it?

The rubbing polished the flat film. Sherwin-Williams and Benjamin Moore call that burnishing or marring. It is common with flat paint, abrasive cleaners, and anything that rubs the wall, including furniture. More scrubbing makes the shiny spot larger.

### Can I dull a burnished spot back to flat?

Neither company’s page describes a cleaner that restores the original flat look. Sherwin-Williams says to repaint once the marring is there. Washing removes dirt. It does not undo a change in the sheen of the film.

### What sheen should I use in a hallway so it does not burnish?

Avoid flat. Sherwin-Williams points to semi-gloss or gloss in high-traffic areas. Benjamin Moore points to eggshell, satin, pearl or semi-gloss. Pick from that range based on how flawed the wall is and how often it is washed. Higher sheen shows dents more and cleans more easily.

### How long after painting can I wash without burnishing?

Both the Sherwin-Williams marring page and the Benjamin Moore burnishing page say to wait at least two weeks. A different Benjamin Moore cleaning article says to wait until the paint has cured, and at least 30 days. If your data sheet names a time, use that.

### How is burnishing different from flashing?

Burnishing is wear. It shows up later, in the shape of the rubbing. Flashing is uneven sheen from the way the paint went on, often over a patch or a lap, and it is there as soon as the coat dries. The fixes are different.
