It is a real engineering choice rather than a finish: brass holds its dimensions under repeated heating far better, which is exactly what a burner port needs if the flame is to stay the same shape for twenty years. The trade is that brass discolors, and that it cannot be treated the way a steel burner is treated. ### The three things that ruin them - **Dishwasher detergent.** Alkaline, and it strips the surface permanently. - **Abrasive pads and caustic oven cleaner.** Same outcome, faster. - **A wire pushed through the ports.** It widens them unevenly, and an over-opened port gives a lazy, lifting flame that no amount of cleaning fixes. ### What a service actually restores An even ring of blue flame that sits down on the port and holds at the bottom of its range. The simmer is the test, because a burner with narrowed ports will still look fine at full heat and will not hold low. That is why this service ends with every burner taken down to its lowest setting and watched, rather than lit and signed off. ### What it costs A brass burner service starts at $135 for a cooktop or the top of a range. Parts, where a burner is genuinely past cleaning, are quoted separately and shown to you before they are ordered. What this involves Caps, rings and ports cleaned by hand — never with an abrasive or a caustic Ports gauged rather than eyeballed, so the flame comes back even Replacement only for brass that is cracked or eroded, and we show you why Look at what is actually wrong with the burner Discoloration, spill, erosion at the port edge and a crack are four different conditions and only two of them mean a part. Brass darkens with heat and that alone is not a reason to replace anything. Strip, soak and clear Caps and rings off, soaked rather than scrubbed, and every port cleared with a gauge rather than a wire that can widen it. A port opened too far burns as badly as a port half blocked, which is why this is done with a tool and not with whatever is in the drawer. Reseat and check the flame A brass cap has one right position and it is not always obvious. Seated square, the flame ring is even all the way round and sits down on the port; seated proud, it lifts, it clicks and it will not simmer. Say plainly what is worth replacing If a cap is cracked or a port has eroded past the point where it will meter, we say so and show you the burner next to a good one. If it is sound, we say that too, and the visit is a service rather than a parts bill.

Brass discolors with heat — that is what brass does, and on a burner that gets to flame temperature several times a day it happens quickly. It is cosmetic. What is not cosmetic is a crack across the cap, an eroded port edge, or a burner that has lost its shape, and those are visible once it is clean. ### Can I put them in the dishwasher? No. Dishwasher detergent is alkaline and it takes the finish off brass permanently, which is the single most common way these burners get ruined by kindness. Warm water, a soft brush, and time. If something is properly baked on, a longer soak does what a harder scrub should not. ### Is this worth paying for, or should I just do it myself? If you are willing to be patient with a soak and a paper clip, a good deal of it you can do yourself and we would rather you did — it is in the guide on this site. Where the visit earns its money is the gauging: ports that have been opened unevenly by a previous cleaning are the reason a burner will not simmer, and that is not something to judge by eye. ### How often should this be done? On a range that is genuinely cooked on, once a year is sensible and after any significant boil-over is better. The signal to watch for is the simmer: the low flame is the first thing to go when ports start narrowing, long before anything obvious happens at full heat. --- **[Read full article: Brass burner service & rebuild](https://bertazzonimiami.support/services/brass-burner-service/)**
