Knowing how to clean sunglasses properly matters more than most people realise. A few seconds of wiping with a shirt, tissue or paper towel can leave microscopic scratches across the lenses, while the wrong cleaning product can damage coatings that cannot simply be replaced. This is particularly important with premium sunglasses, where optical lenses, anti-reflective treatments, mirrored finishes and polarised coatings can require more careful handling.
The good news is that cleaning sunglasses safely does not require complicated products or expensive equipment. The safest method is simple: rinse away loose particles, use a small amount of suitable lens cleaner or mild dish soap, rinse again, and dry with a clean microfibre cloth. The important part is understanding why each step matters and knowing which common shortcuts should be avoided. If you are still choosing your next pair, understanding how to choose sunglasses for your face shape can also help you focus on frame proportions rather than simply choosing based on appearance.
The Two Minute Method
The safest way to clean sunglasses is also one of the simplest. Instead of trying to remove dust by rubbing the lenses immediately, use water to loosen and wash away particles first. This reduces the risk of dragging grit across the lens surface and is especially useful when cleaning expensive optical frames.
What you need
You only need a few things to clean sunglasses safely. Start with clean, lukewarm or room-temperature water and a clean microfibre lens cloth. If the lenses need more than a simple rinse, use a lens-cleaning spray specifically designed for coated optical lenses, or a tiny amount of mild, lotion-free dishwashing liquid diluted with water.
The microfibre cloth should itself be clean. A cloth that has collected dust, skin oils or particles inside a pocket or bag can simply transfer those contaminants back onto the lenses. It is worth washing your microfibre cloths regularly and keeping them somewhere clean rather than loose in a handbag, gym bag or car.
Step by step
Begin by washing your hands so you do not transfer grease to the lenses or frame. Hold the sunglasses under a gentle stream of lukewarm or room-temperature water and allow the water to rinse away loose dust and particles. Avoid hot water, as excessive heat can affect certain lens coatings and frame materials.
If there are fingerprints, sunscreen marks or oily residue, place a very small amount of mild dish soap on your fingertips, dilute it with water and gently clean both sides of the lenses. Do not scrub. Let the water and soap do the work, then rinse thoroughly so no residue remains.
Shake off excess water carefully and use a clean microfibre cloth to dry the lenses with gentle, straight movements. There is no need to apply pressure. If you use a dedicated lens-cleaning spray, spray the product onto the microfibre cloth rather than directly onto the frame whenever the manufacturer recommends this approach. This helps prevent liquid from entering hinges or other small components.
For premium collections such as Garrett Leight sunglasses, taking a few extra seconds to clean the lenses correctly is preferable to repeatedly polishing them with whatever cloth happens to be nearby. The aim is to remove contamination, not polish the surface aggressively.
What to Never Use
Many scratched lenses are not damaged because the owner used an obviously dangerous chemical. They are damaged because an everyday object was used as a cleaning cloth. The surface of a lens can look perfectly smooth while carrying tiny particles capable of creating fine scratches when pressure is applied.
Shirt hems, tissues and paper towels
Your shirt may seem like the obvious solution when your sunglasses suddenly become dirty, but clothing is not designed to clean optical lenses. Shirt fabric can hold dust and particles, while rougher fibres can create fine scratches over time. Paper towels and tissues have a similar problem. Even when they feel soft, their fibres and texture are not necessarily suitable for coated lenses.
The bigger issue is the habit of wiping a dry lens. If there is sand, dust or grit on the surface, rubbing it across the lens can create abrasion. Rinsing first is one of the easiest ways to avoid this, particularly if you are wearing your sunglasses regularly outdoors.
Household glass cleaner, alcohol wipes and hand sanitizer
Glass cleaner for windows is not the same thing as optical lens cleaner. Household cleaning products can contain ingredients that are unsuitable for sunglasses coatings, frames or lens treatments. Alcohol wipes and hand sanitiser should also not be treated as universal lens-cleaning solutions, particularly when the lens manufacturer does not specifically approve them.
When in doubt, use water and a clean microfibre cloth, or choose a lens cleaner designed specifically for eyewear. Avoid experimenting with kitchen, bathroom or automotive cleaning products simply because they are marketed for glass or shiny surfaces.
Polarized and Mirrored Lenses Need a Lighter Touch
Polarised and mirrored sunglasses deserve the same basic cleaning method, but extra care is sensible because their optical performance and appearance depend on specialised lens construction and coatings. Polarisation itself is not something that can simply be polished back into place if a lens is damaged, while mirrored finishes can show marks, coating damage or abrasion particularly clearly.
Never try to remove a stubborn mark from a mirrored lens by increasing pressure. Rinse it first, use an appropriate lens-cleaning solution if needed and dry gently with a clean microfibre cloth. If the coating appears to be peeling, bubbling, discolouring or developing unusual patches, stop trying to clean it and have the lenses assessed professionally.
Looking After the Frame
Cleaning sunglasses is not only about keeping the lenses clear. The frame also comes into contact with sunscreen, sweat, skin oils, dust and humidity, particularly around the nose and temples. Regular gentle cleaning helps preserve both the appearance and the mechanical condition of a quality frame. The shape of the frame matters too: a pair that suits your proportions is more likely to become an everyday favourite, which makes proper maintenance even more worthwhile.
Acetate
Acetate frames can be remarkably durable, but they still benefit from careful cleaning. Use lukewarm water and a mild cleaning approach rather than aggressive chemicals or abrasive cloths. Avoid prolonged exposure to high heat, especially in places such as a closed car on a hot day, because excessive heat can affect the shape and finish of acetate.
If you own a statement frame from Cutler and Gross (Kingsman), the material and finish are part of what gives the frame its character. Cleaning should preserve that finish rather than attempting to make the acetate look artificially polished.
Metal and titanium
Metal and titanium frames can generally be cleaned with the same gentle approach, but moisture should not be left sitting around joints or small openings. After washing, pay attention to the bridge, temples and areas around the hinges. A clean microfibre cloth can remove remaining moisture without putting unnecessary pressure on the frame.
When choosing between different frame shapes, it can be useful to look beyond colour and styling. Our guide on which Garrett Leight frame fits your face explores how frame proportions can work with different facial shapes, which is particularly useful when investing in a pair you expect to wear for years.
Nose pads, hinges and screws
Nose pads, hinges and screws collect oils, sweat and product residue more easily than larger surfaces. Water and gentle cleaning are usually enough for routine maintenance. Avoid forcing a cloth into a hinge or trying to scrape away dirt with a pin, toothpick or other sharp object.
If a screw is loose, a hinge feels stiff or a nose pad has become discoloured or damaged, professional adjustment is safer than attempting a repair with household tools. Small components can be replaced or adjusted without risking damage to the entire frame.
Scratches: What Can Be Fixed and What Cannot
A genuine scratch in an optical lens generally cannot be cleaned away. Cleaning removes dirt, grease and residue from the surface; it does not restore material that has already been scratched. Fine marks may sometimes be difficult to see in normal lighting, but that does not mean they can safely be polished out at home.
Whether a scratched lens can be replaced depends on the frame, lens type and manufacturer or optician. For valuable sunglasses, replacing a damaged lens is usually a much safer approach than trying an internet remedy that could make the damage worse.
Why toothpaste and baking soda make it worse
Toothpaste and baking soda are frequently recommended online as DIY solutions for scratched glasses, but they are abrasive materials. The idea is to polish away a microscopic layer of the lens, yet this can damage optical surfaces and coatings rather than restore them. Even if a scratch appears less visible for a short time, the lens may have been permanently altered.
The same principle applies to car polish, abrasive compounds and other household polishing products. Sunglasses lenses are optical components with specific coatings, not ordinary pieces of glass that should be sanded or polished at home.
Storing Them So the Frame Stays True
Good storage is part of cleaning and maintenance because it prevents many of the situations that create scratches in the first place. Keep sunglasses inside a protective hard case whenever they are not being worn rather than placing them loose in a pocket, bag or car compartment.
Always place the sunglasses with the lenses facing upward when a case or surface allows it, and avoid putting other objects on top of them. Do not leave premium frames exposed to extreme heat for long periods, particularly inside a parked car. Heat can affect certain materials, coatings and frame geometry.
Keep your microfibre cloth clean as well. A dirty cloth can turn an otherwise careful cleaning routine into repeated surface abrasion. Washing it according to its care instructions and storing it with the sunglasses in a clean environment makes a surprisingly large difference.
Beach, Car and Gym: Where Frames Actually Get Ruined
Everyday environments are often more damaging to sunglasses than the act of cleaning them. At the beach, salt, sunscreen and sand can accumulate on the lenses and frame. Never wipe sand away while the lenses are dry. Rinse thoroughly with fresh water first, then clean gently.
The car presents another problem: heat. Leaving sunglasses on a dashboard or inside a closed vehicle can expose both frames and lenses to temperatures far beyond what they experience during normal wear. The gym brings sweat, skin oils and moisture into contact with the frame, particularly around the nose pads and temples. Rinsing and gently drying the sunglasses after heavy use is better than allowing residue to build up.

When to Hand Them to an Optician
An optician should be your first stop when a lens is genuinely scratched, a coating appears damaged, the frame is visibly bent or the hinges no longer operate correctly. Professional eyewear specialists have the appropriate equipment to assess whether a lens can be replaced and whether the frame can be safely adjusted.
This is especially relevant when you are unsure whether a mark is dirt, a surface coating issue or an actual scratch. Trying increasingly aggressive cleaning methods can turn a minor cosmetic problem into permanent damage. If a quality frame has developed a problem that water and gentle cleaning cannot solve, stop experimenting and have it inspected.
Frames Worth the Care: Garrett Leight, Cutler and Gross, Mr Leight
Quality eyewear deserves a maintenance routine that reflects the materials and craftsmanship behind it. Mr Leight, for example, is known for combining refined design with carefully considered materials, making proper storage, gentle cleaning and professional adjustment worthwhile parts of owning the frame.
The broader Garrett Leight collection offers another example of why everyday eyewear care matters. A well-made frame is designed to be worn repeatedly, but regular exposure to fingerprints, sunscreen, sweat, dust and changing temperatures makes simple maintenance essential. The same applies when browsing Garrett Leight glasses for optical styles: clean lenses and a correctly aligned frame are part of the experience of wearing them.
Premium sunglasses are ultimately an investment in something you use repeatedly, so the best maintenance routine is also the simplest one. Rinse away particles before wiping, use a clean microfibre cloth, choose products made for optical lenses, avoid abrasive household hacks and store the frame in a protective case. These small habits take only a few minutes, but they can prevent the scratches, coating damage and frame problems that are far harder to undo.
