Compatible with all DEF fluids, it restores engine power and fuel efficiency by maintaining the selective catalytic reduction system. Ideal for diesel vehicles prone to crystallization from low-speed or stop-and-go driving, it should be used every 5,000 miles to prevent costly emissions system failures. ## Description RISLONE® DEF CRYSTAL CLEANTM Diesel DEF & SCR Emissions System Cleaner is a propriety blend of DEF (Diesel Exhaust Fluid) / AdBlue® compatible cleaning agents and surfactant detergents specifically designed to be safe to use and work on SCR (Selective Catalyst Reduction) systems. DEF Crystal Clean gives a cleaning effect on the entire SCR system by working to dissolve the white crystal deposits that form in the tank, pump, heater, sender, lines, injector, decomposition tube / reactor and mixer. These deposits can interfere with the normal operation of the SCR emissions system and engine, increasing fuel consumption and reducing engine power. This reduced power can lead to operating in limp mode where the vehicle will drive slowly, or become undrivable. This process restores function and with regular use maintains efficiency of the SCR. DO NOT ADD TO DIESEL FUEL TANK. INSTRUCTIONS: DEF Crystal Clean is specifically designed to only be installed in the Diesel Exhaust Fluid / AdBlue tank which usually has a blue cap. Do not add to the diesel fuel tank. * Light Truck or Mid-Size to Large SUV - 5 to 9 gallon tank capacity install full bottle into DEF tank. *Car or Small SUV - 3 to 5 gallon tank capacity use approximately 1/2 bottle. *Medium and Heavy Duty Diesel Trucks - 10 to 20 gallon tank capacity use 2 bottles. Pour DEF Crystal Clean into mostly full DEF tank or add and fill tank with diesel exhaust fluid. If light is still on after 250 miles or a few days of driving, second application may be required, or mechanical attention is needed. NOTE: Works with all approved diesel exhaust fluids. Some vehicles use a special filling adapter to install DEF / AdBlue into the tank. For those vehicles use special funnel or pour into mostly empty DEF / AdBlue bottle and install in system. ## Features - Excellent for diesel vehicles driven regularly at slow speeds, low loads, short durations or make frequent stops as these are more prone to having the problem of crystallization deposit build up in the SCR system. - Regular use every 5,000 miles not only keeps the system clean, but works to prevent the white crystallization issues from returning. - Will not void manufacturer’s new vehicle warranty. Specifically designed and safe to use on vehicles which have DOC catalytic converters, DPF particulate filters, SCR selective catalytic reduction devices, ASC ammonia slip catalyst or DEF / AdBlue systems. - Works with all AdBlue, Aria 32 (Automotive Nitrogen Oxide Liquid Reducing Agent), AUS 32 (Aqueous Urea Solution), BlueHDi, BlueTEC, Cummins, DEF UREA, Duramax, EcoDiesel, PowerStroke, TDI Clean Diesel, and many more. - DEF Crystal Clean is specifically designed to only be installed in the Diesel Exhaust Fluid / AdBlue tank which usually has a blue cap. Do not add to the diesel fuel tank. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CRSVRXXQ | | Best Sellers Rank | #54,234 in Automotive ( See Top 100 in Automotive ) #75 in Fuel System Cleaners | | Brand Name | Rislone | | Customer Reviews | 4.7 4.7 out of 5 stars (29) | | Global Trade Identification Number | 10078615047847 | | Included Components | (6) DEF and SCR Treatment | | Item Form | Liquid | | Item Type Name | Diesel DEF & SCR Emissions System Cleaner | | Item Volume | 11 fluid ounces | | Item Weight | 6.1 pounds | | Manufacturer | Bar's Products | | Material Features | Automotive | | Model Number | 4784-6PK | | Number of Items | 6 | | Part Number | 4784-6PK | | Scent | Unique | | Size | 11.8 Fl Oz (Pack of 6) | | Special Features | Concentrated | | Specific Uses For Product | Automotive | | Surface Recommendation | Automotive | | Unit Count | 70.8 Fluid Ounces | | Warranty Description | Please see manufacturer | ## Product Details - **Brand:** Rislone - **Item Form:** Liquid - **Material Feature:** Automotive - **Scent:** Unique - **Specific Uses For Product:** Automotive ## Images ![Rislone 4784-6PK Crystal Clean Diesel DEF & SCR Emission Cleaner, 6-Pack - Image 1](https://m.media-amazon.com/images/I/813ZGvcnD2L.jpg) ## Frequently Bought Together - Rislone 4784-6PK DEF Crystal Clean™ Diesel DEF & SCR Emissions System Cleaner, 11.8 oz (Pack of 6) - Rislone 4780-6PK Diesel DEF Treatment | Prevents AdBlue/DEF Fluid Crystallization, 8 oz (Pack of 6) - Rislone® 4744-4PK DPF Clean™ Diesel DPF, Exhaust & Emissions System Cleaner, 16.9 oz, 4-Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/604398632-rislone-4784-6pk-crystal-clean-diesel-def-and-scr-emission](https://www.desertcart.hr/products/604398632-rislone-4784-6pk-crystal-clean-diesel-def-and-scr-emission) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-15*
