FEYNLAB® Rubberized Clay Sponge Just as effective as traditional clay bars, the Feynlab rubberized polymer sponge effectively removes above surface bonded contaminants. When used with Feynlab Prime, this clay sponge will safely remove paint overspray, rail dust, brake dust, and other bonded contaminants from the surface of automotive paint, glass, moldings, chrome and smooth plastics. The rubberized polymer sponge is proven to last 3x times longer than conventional clay bars. Say goodbye to constantly needing to flip the clay bar after each section! Just clean it in your wash solution and keep rolling. This sponge fits perfectly in the palm of your hand for an exceptional user experience. Also, with this technology you can drop your sponge on the shop floor because simply rinsing the sponge with clean water will put you right back in business! This sponge can be used over and over again to restore brilliance to automotive surfaces. We also recommend that brand new sponges be “broken in” on glass before using on Automotive paint. This removes the transportation barrier from the manufacturing of the clay, and will reduce marring. Directions: Wash with Feynlab® Pure Wash and dry your car thoroughly to remove as much dirt, grime, and other contaminants as possible. Dilute Prime 1:15 for use as clay lubricant. Note this is different than the dilution specified on the bottle. Spray a significant amount of Feynlab Prime on the sponge and car paint. Slide the sponge with the rubberized polymer portion facing the surface gently back and forth over the lubricated area using little to no pressure as possible while still maintaining control of the sponge. Add more lubricant if the sponge sticks while you’re trying to slide it. Keep moving sponge over area until the surface feels smooth. Dry area using a clean microfiber towel. Repeat on the rest of the vehicle and it is now ready to add your favorite protectant! *Note* While Feynlab Prime is recommended, you may use your clay lube of choice. Frequently Asked Questions What is a clay sponge? A clay sponge is a rubberized polymer block that removes bonded contaminants from car paint. The Feynlab® Rubberized Clay Sponge uses polymer material instead of traditional clay to grab embedded particles like brake dust, tree sap, and industrial fallout. The sponge design offers better grip and control during decontamination work. Clay sponge vs traditional clay bar - what's the difference? Clay sponges use rubberized polymer while clay bars use natural or synthetic clay material. The polymer construction makes the clay sponge more durable and reusable across multiple detailing sessions. Sponges also provide easier handling with their block shape versus the malleable clay bar format. What contaminants does a hand sponge remove from car paint? The hand sponge removes brake dust, tree sap, road tar, industrial fallout, and paint overspray bonded to clear coat. These contaminants embed into the paint surface and cannot be removed through regular washing. The Feynlab® clay sponge grabs these particles while preserving the underlying paint finish. How long does a clay bar sponge last? A clay bar sponge typically lasts through multiple detailing sessions when properly maintained. The rubberized polymer material resists tearing and can be rinsed clean between uses. The Feynlab® clay sponge maintains effectiveness until the polymer surface becomes too smooth to grab contaminants effectively. Is sponge clay safe on clear coat? Sponge clay is safe on clear coat when used with proper lubrication and light pressure. The polymer material removes contaminants without scratching when kept wet with clay lubricant or soapy water. Always work in straight lines and rinse the sponge frequently to prevent trapped particles from marring the finish. What finish do clay sponges leave on paint? Clay sponges leave paint surfaces smooth and contaminant-free with the original gloss intact. The decontamination process removes embedded particles that cause rough texture, revealing the clean paint underneath. The Feynlab® clay sponge prepares surfaces for polishing or coating application by creating a perfectly clean foundation. Where can I use a bar sponge on cars? Use the bar sponge on all painted exterior surfaces including panels, bumpers, and trim pieces. The polymer material works safely on clear coat, single stage paint, and painted plastic components. Avoid using on soft surfaces like convertible tops or unpainted rubber trim pieces. How do I maintain my sponge bar after use? Rinse the sponge bar thoroughly with clean water to remove trapped contaminants and lubricant residue. Store in a clean, dry location away from direct sunlight to prevent polymer degradation. Check the surface before each use and replace when the polymer becomes too smooth to effectively grab particles. For lubrication during use, consider our clay bar lubricant.
