Some items have more than their fair share of dirt that obscures their original or near-original appearance. Naturally, cleaning them before listing comes to mind. However, cleaning may do more harm than good for certain items. While you’re after improving the condition of the item, incorrect or excessive cleaning practices may lower an item’s value instead of raising it. We’ve researched nine items you’re better off leaving alone, along with tips for non-invasive cleaning, and what items are dirty enough you shouldn’t source them. ## Why cleaning items is tempting Cleaning items is an important part of a reseller’s process, especially when you are selling on platforms like eBay and Mercari. These marketplaces rely on [**photos of an item**](https://www.sellraze.com/blog/accidentally-professional-a-lazy-resellers-guide-to-photos-that-actually-sell?ref=sellraze.ghost.io) for sale. Buyers gauge listings based on photos and prefer clean items. Restoring items to their original state feels good for a reseller, along with the [**hopes of selling it for a better profit margin**](https://www.sellraze.com/blog/will-washing-thrifted-clothes-increase-resell-value?ref=sellraze.ghost.io). Online shops that specialize in thrifted but clean clothing quickly gain a following from buyers who prefer their items ready to wear. The same goes for clean household items; buyers prefer items they don’t have to clean extensively when they arrive. ## When cleaning does more harm than good But DIY cleaning, with all its good intentions, may ruin an item instead of improving it. For example, using oxybleach on silk will damage the fabric instead of removing stains. Delicate items such as vintage lace may react poorly to bleach. Another example is scraping dirt from a collectible statue. The friction may cause scratches that make the item less desirable and leave permanent damage. Some collectors prefer items with a “lived-in” appearance, especially items coming from famous people. Cleaning them to the point of almost new removes this sought-after quality. Mold and [**heavily-stained items with blood**](https://www.traumaservices.com/blog/how-to-get-blood-out-of-clothes/?ref=sellraze.ghost.io) and other bodily fluids are beyond the cleaning capabilities of the average reseller. These biohazards need a professional who knows the proper way to treat items without causing harm to the object and to the person handling it. Some stains may reveal deeper problems about the item. For example, moth stains and damage indicate an infestation which could spread through the rest of your inventory. Food stains attract insects which may have already damaged the inner parts of bags and shoes. ## 9 thrifted items resellers should not attempt to clean themselves ![a camel-colored suede handbag](https://storage.ghost.io/c/e9/2c/e92c0268-0a3c-45b5-8c3a-b81ee6ef33fd/content/images/2026/06/pexels-godisable-jacob-226636-1936848.jpg) _[Photo by Godisable Jacob from Pexels](https://www.pexels.com/photo/woman-wearing-brown-leather-tote-bag-1936848/?ref=sellraze.ghost.io) 1._ Unless you’re experienced in restoring items, we recommend seeking the help of professionals instead of cleaning these items by yourself. ### Vintage fur coats and accessories Animal fur is notoriously prone to insect infestations, and vigorous scrubbing may cause the fur to shed from coats, boots and hats. Household cleaning products may eliminate the pests but also damage the item. ### Books and other paper items Never attempt to do any liquid-based cleaning for these items. The best you can do for ephemera, stationery, and books is to gently brush dust off them. For torn covers and pages of vintage books, it’s best to see a restorer. ### Silk and beaded garments If you are unfamiliar with silk, leave the cleaning to a professional instead. This is the same with traditional textiles that may no longer be produced today. Delicately-beaded items like gowns and coats should be left alone aside from a gentle brushing. The beads may break in the wash, which may lower its price. ### Vintage leather items with heavy staining Leather gets dry even with routine cleaning. Only a professional can safely get out heavy stains on leather and make sure it stays shiny and supple after. ### Smoke-damaged items Some people mistakenly use air fresheners to neutralize smoke odors in thrifted fabric, only to find out it's making the smell worse. As with the other items on this list, approaching professional cleaners and restorers is the best way to get out deep smoke smells. ### Antique and handmade rugs DIY rug cleaning can be risky: dyes may bleed, rugs may shrink after washing, and they are prone to mold if not dried properly. Professional rug cleaners can check the kind of dye used in the rug and what cleaning agent is best to use. ### Designer items like handbags and purses These items are made of multiple materials where a single household cleaner might not effectively clean. For example, a handbag might be made of different kinds of leather, plus hardware. A cleaner that works on one material may damage or fail to clean another. Improper handling may also cause these items to lose their original shape, which in turn lowers resale value. ### Paintings, artwork, and photographs Surface cleaning, especially with liquids, can do more harm than good to paintings and photographs. A light dusting would be enough. If professional cleaning is necessary, consult a conservator or restorer before reselling the item. ### Electronics Do not attempt to clean the inside unless you are a technician. ## Minimally-invasive cleaning methods for your resale items ![airing out a scarf](https://storage.ghost.io/c/e9/2c/e92c0268-0a3c-45b5-8c3a-b81ee6ef33fd/content/images/2026/06/still-life-waving-fabric-air.jpg) _[Image by freepik](https://www.magnific.com/free-photo/still-life-waving-fabric-air_94944780.htm?ref=sellraze.ghost.io#fromView=search&page=1&position=9&uuid=7da7ca1c-7d2a-496b-a661-8cb806173892&query=bleached+cloth)_ For items not on the list, or for items with minimal dirt on them, you can try cleaning techniques like **brushing dust off with soft brushes**, **vacuuming on low,** and **using microfiber cloths.** These are less likely to damage the items but are also less effective in removing stubborn dirt and grime. **Airing out** helps to remove odors. For some items, a **brief exposure to sunlight** may also help, but make sure to check the label especially on clothes. Always indicate in your listing what cleaning methods were used in the item or state there was no cleaning done. This step is crucial especially to sellers who sell [**NWT items**](https://www.sellraze.com/blog/blog-nwt-meaning-reselling?ref=sellraze.ghost.io). Transparency should always be first in any resale business. If you decide to clean items by yourself, spot test first to avoid possible fading and bleeding. ## Thrift store items to skip sourcing ![moldy fabric](https://storage.ghost.io/c/e9/2c/e92c0268-0a3c-45b5-8c3a-b81ee6ef33fd/content/images/2026/06/rough-outdoors-texture-background-with-yellow-paint.jpg) _[Image by freepik](https://www.magnific.com/free-photo/rough-outdoors-texture-background-with-yellow-paint_10746832.htm?ref=sellraze.ghost.io#fromView=search&page=1&position=47&uuid=3c633184-7b34-4452-87f3-fe36e1747f51&query=mold+in+clothing)_ These items take too much of your time and resources to clean and restore. You’re usually better off not adding them to your inventory. - **Mattresses.** Leave these to the direct buyers rather than purchasing them for resale. Professional cleaning and sanitizing can be expensive. - **Moldy items.** Items like these are often beyond cleaning and restoring. - **Items with a strong unknown smell.**There’s a chance the odor won’t totally come off. ## Should I clean and list this item? Before deciding to clean an item ready for listing, there are several factors to consider. - The amount of time needed for cleaning - Whether it can be cleaned by yourself or by a professional - Will cleaning increase the value of the item? - Will the value outweigh the expense of having it cleaned professionally By taking these things into account, you’ll save time and money while deciding whether you’ll clean and list the item, list it as it is, or not to list it altogether. ## The Verdict Cleaning can help increase or preserve an item’s resale value, but only when done correctly. It can also lower an item’s value when the buyer prefers it on an as-is basis, or when damages occur during cleaning. The goal is the same: maximize profit and minimize wasted time and effort.
