DETAIL GUARDZ Dirt Lock Car Wash Insert — White, fits 3–8 gal buckets, grit-trapping venturi action

The DETAIL GUARDZ Dirt Lock Car Wash Insert is a white, self-locking bucket insert that traps grit beneath the wash screen so your mitt stays cleaner and reduces swirl marks while washing.

Designed for car enthusiasts and professional detailers, this durable insert retrofits standard 3–8 gallon round buckets to keep abrasive debris away from your wash mitt. Its directional channels and venturi-style action pull dirt below the screen each dunk, maintaining safer wash water without pumps or filters. Built from high-strength resin in Canada, the insert combines a secure fit with low-maintenance operation.

How does the Dirt Lock insert keep grit away from my wash mitt?

The insert uses angled, directional channels beneath a perforated screen to guide particulate down and away from the surface. Each dunk creates a Venturi-style flow that helps sweep contaminants underneath the insert instead of back onto your mitt. This reduces the chance of dragging abrasive particles across clearcoat.

• Perforated top screen prevents large debris from resurfacing
• Directional channels funnel grit to the bucket bottom
• Venturi flow improves passive filtration with each dip

Will it fit my bucket and stay secure during use?

The Dirt Lock insert is engineered to fit most round buckets between 3 and 8 gallons with bases around 10.2–10.72 inches. Flexible rubber tabs conform to the bucket wall for a snug fit, while a weighted body keeps the insert seated during aggressive scrubbing. Installation is tool-free — press it down until it locks into place.

• Compatible with standard 3–8 gallon round buckets
• Flexible rubber tabs for a tight, universal fit
• Weighted construction prevents floating or shifting

How durable and easy to maintain is this insert?

Manufactured from premium, high-strength resin, the insert resists cracking and wear in repeated commercial or home use. Because filtration is passive, there are no moving parts to service; simply lift, rinse, and reinstall as needed. The material cleans quickly and withstands detergents commonly used in automotive washing.

• High-strength resin construction for long life
• Simple rinse-clean maintenance — no filters to replace
• Formulated to resist common wash chemicals and wear

Does using the Dirt Lock change my wash routine?

The insert integrates with standard two-bucket or single-bucket methods without added equipment. It lets you continue using your preferred soap and mitt while improving water hygiene and minimizing swirl risk. For best results, dunk and wring your mitt against the insert before each pass.

• No pumps, hoses, or accessories required
• Compatible with your existing mitts and wash soaps
• Works well within two-bucket systems or as a solo improvement
