Decent, but it's tough on the environment.

TL;DR A 6-gallon rectangular PP bucket that replicates the two-bucket wash method in one rolling unit via a removable divider. The 3-gallon-per-side working volume falls below the standard mitt-clearance threshold, and the OEM built-in grit traps have no community confirmation of effectiveness yet · the product debuted at SEMA 2024 and the owner review base is still very thin. The caster-and-caddy system is the standout feature; the volume is the real limitation.
The Griot's Garage Ultimate Wash Bucket II is a 20.6 × 12 × 12-inch rectangular polypropylene bucket designed to compress the two-bucket wash workflow into a single rolling container. The removable Dirt-Tight divider splits the 6-gallon interior into two 3-gallon compartments · one for soapy wash water, one for rinsing the mitt · each with a dedicated built-in lower grit trap. Standard round grit guards cannot seat in the rectangular footprint. A 3-inch locking caster frame, integrated tool caddy, Secure-Fit snap-on lid, upper grille, and built-in measuring marks complete the system. The concept addresses a real workflow annoyance · moving two separate buckets around a vehicle · but the 3-gallon compartments fall below the 3.5-gallon standard where wash-mitt clearance becomes comfortable on full-size vehicles. Made in the USA. The bucket is new enough (SEMA 2024 debut, only a handful of owner reviews at time of scoring) that no community data on grit-trap effectiveness or long-term durability is available.
Right pick for a detailer who primarily washes sedans or compact vehicles, values the single-rolling-unit workflow, and has limited garage floor space. Skip it if you regularly wash trucks, SUVs, or vans · 3 gallons per side will constrain mitt clearance and force mid-job water changes. A standard 5-gallon purpose-built detailing bucket (such as the Chemical Guys Cyclone system or Adam's Polishes 5-gallon bucket) gives better working volume and community-confirmed grit management at a similar price point.
No chemical exposure pathway from the bucket itself. Constructed from polypropylene (PP #5) rather than the more common HDPE #2: PP #5 is not accepted in curbside recycling in many US municipalities and is more susceptible to UV-driven surface chalking under prolonged outdoor storage when no UV-stabilization additive is disclosed · none is confirmed on the current listing. No BPA-free claim is documented. The environmental score reflects the PP #5 material profile relative to HDPE #2 purpose-built detailing buckets.
No. The Ultimate Wash Bucket II is rectangular (20.6 x 12 inches), and standard round grit guard inserts (Grit Guard brand, Chemical Guys Cyclone, generic 10.5-11 inch) are designed for round buckets and cannot seat flat in a rectangular footprint. Grit management is provided by Griot's own built-in lower grit traps · one per compartment. There is no separately-purchased round insert option for this bucket.
Yes · the Dirt-Tight divider is removable. Without it, you have a single 6-gallon rectangular compartment. However, the built-in lower grit traps are individual to each side, so removing the divider means you have two half-width grit traps across the floor instead of one centered trap. Whether this is adequate depends on your wash workflow.
For compact cars and sedans, 3 gallons per side is workable but below the 3.5-gallon threshold where wash-mitt clearance becomes comfortable. For trucks, SUVs, or vans, 3 gallons per side is likely to require more frequent water changes or force a compromise in mitt submersion. The standard recommendation in the detailing community is 4.5-5 gallons of wash water.
