Have Chemical Guys come up with the grit guard killer? The Cyclone Dirt Trap bucket insert sits at the bottom of your bucket(s) while you wash filtering the water non-stop. It's the filter that never stops. The cyclone Dirt Trap help eliminates wash swirls and scratches with Chemical Guys Cyclone Dirt-Trap Filtration Technology. The round wash screen separates abrasive dirt and silt from clean and soapy wash water through nearly 300 cyclonic dirt funnels. Separating dirt from clean and soapy water keeps nasty abrasive grit off of your wash wash mitt, and therefore it's going nowhere near your paintwork for a scratch-less car wash. The cyclone funnels of the Dirt Trap separate dirt through centripetal force and push it through tiny holes underneath the wash screen. The dirt remains trapped underneath the funnels and cannot easily flow back up through the tips once the mitt is pulled out from the water. The one way Cyclone Filtration system is a passive filter that never needs replacing and does not rely on moving parts, no disposable filters, and requires no maintenance or energy to set up, use, or store. In summary, it's next step in safe car washing technology. The Chemical Guys Cyclone Dirt Trap is tailored to fit snugly at the bottom of any car wash bucket for superior filtration and dirt stopping power. Comes in one standard size and fits nicely in a 12" diameter bucket - which is generally the standard bucket size anyhow.
