  • KEEPS DIRT AT THE BOTTOM: Directional channels trap grit and debris below the insert so your wash mitt stays in cleaner water, reducing swirl marks and scratches during car washing.
  • UNIVERSAL BUCKET FIT: Fits most standard 38 gallon round buckets (10.210.72" base). Flexible rubber tabs create a snug, secure fit for home users and professional detailers.
  • SELF-LOCKING, STAYS PUT: Simply press into place, no tools needed. Weighted, durable construction keeps the insert locked at the bottom, even during aggressive washing.
  • ADVANCED DEBRIS FILTRATION: Venturi-style flow pulls dirt underneath the screen with each dunk, continuously filtering wash water without power or accessories.

Description

Our patented design utilizes the motion of your hand to pump and trap debris underneath the screen. The Dirt Lock has a complex Venturi filtering system that manipulates the flow of water in a downward direction. This allows dirt particles to collect underneath the screen without a way for it to re-enter into the clean water. In short, every time you pump your hand in the bucket you are cycling the dirt underneath the screen and replenishing clean water above to help prevent swirl-marks and scratches on the painted surface. ONE Dirt Lock will filter your wash water like you have never seen before. Protect your car and eliminate the main cause of swirl marks on your paintwork! Proudly Made In Canada. Fit's inside nearly any 3,4,5,6,7 or 8 gallon standard round wash pail with it's flexible, self-adjusting, rubber locking grips. The Dirt Lock manipulates the flow of water by creating a high pressure underneath the filter and a low pressure above. This results in a tunneling effect and pushes the debris safely underneath the screen and provides much cleaner water above to reuse on your vehicles paintwork! The Dirt Lock comes equipped with rubber grips and also a self-locking feature. Simply push the dirt lock inside almost any 3,4,5,6,7 or 8 gallon round wash bucket and it will automatically adjust itself for the perfect fit. The Dirt Lock is molded from a special plastic resin that sinks like an anchor in the bucket! The Dirt Lock is the ultimate bucket filter to ensure your vehicle is as safe as possible from swirl-marks and scratches. It's locked and loaded with every detail possible to ensure your vehicles finish is maintained to the highest standards. Feel confident knowing you have a proven bucket filter to keep your investment safe. Clean your polishing pads safely and gently within seconds! Simply attach the pad washer attachment into your Dirt Lock bucket filter, place your dirty pads onto the supplied hook and loop handle, spray with our pad cleaner to break down polish and wax, pump pads on the attachment and your done within seconds! Use the Scrub And Pump attachment for added cleaning power with your Dirt Lock bucket filter. Simply push the attachment into place and use it to scrub wash mitts, brushes, hand applicator pads and more! The Dirt Lock scrub and pump attachment works on a spring loaded system to pump cleaner water up and cycle dirty debris safely underneath the screen and out of harms way. The soft rounded scrubbing ridges allow you to scrub and pump away dirt and grime! The Dirt Lock Scrub Wall attachment is a vertical extension of the Dirt Lock’s pressurized cleaning power. Simply snap the attachment into your Dirt Lock bucket filter to easily clean your wheel brushes, wash mitts and more without having to sacrifice hardly any bucket space. Simply scrub your wash media on the side of the Scrub Wall. The debris is now behind the scrub wall screen and is pumped and trapped below the filter to provide cleaner, filtered water for reuse.

Does what's advertised
Color: Blue
I went to home local Lowe's and picked up two 5 gallon buckets one for my dirty water and other for clean water. Having this actually does as advertised it pulls all the dirt and traps it at the bottom of the bucket. Good price and easy to use and fits without issues. It's a bit hard to remove but that says it's doing its job. Don't want it moving around while using it ... show more

Down with grit (literally)
Color: Black
Keeps dirt and grit down at the bottom of your bucket, where gravity deposited it, when you dunk and refresh your wash mitt or sponge or brush into the sudsy water. The durable plastic vanes are designed to keep any swirling water in the upper part of the bucket from disturbing the water at the very bottom layer. Dirt that came off your car sleeps on the bottom until you rinse out the bucket after the wash. Works beautifully. Fits standard 3.5 gallon or 5-gallon buckets. ... show more

Dirt Guard for Bottom of Wash Buckets
Color: Black
Arrived in good condition, in a timely fashion, at a reasonable price (compared to other sites), and works. For 5-gallon size wash buckets. Helps keep dirt out of wash sponges and rags by allowing dirt to settle to bottom and minimizes paint being scratched by it--makes a difference! Wished I bought one of these decades ago. Would do it again. What else is needed? ... show more

Work great - Could Use Better Grips
Color: Gold
I tried spraying water full force at these at the top and then at the bottom, and it was easy to see how much the top lets through but the bottom doesn't. These are a great design and actually do trap dirt. They're awkward to pull out of your bucket, however, as the finger grips are tiny and the the solid design means the traps really stick tight to the edges. ... show more

Surprised how good this is, very high quality
Color: Red
I’ve been using a different bucket insert for the past year and didn’t realize what I was missing out on until I bought this Detail Guardz insert. Quick side comment - this thing is PERFECT in a Buc-ees bucket. It fits like it was made for it, and I’m not just being dramatic, Buc-ees buckets have a bump on the bottom that prevents you from using inserts that have a support leg in the center. The Detail Guardz insert doesn’t have this issue and the rubber gaskets fit like a glove. Perfect combo. As mentioned I was previously using a different insert and every single time I emptied the bucket the insert would fall out which annoyed me. The Detail Guardz insert albeit heavier, does not have this issue at all, it fits like a glove because the rubber gaskets and won’t fall out even if I tried. They clearly did not cut corners designing this thing, it’s hard to tell from pics but each “rib” on the insert has a flared shape so that dirt falls to the bottom easily but won’t as easily come back up even with agitation. They even included push tabs in the center that allow you to grip the insert to remove it but still blocks dirt from floating back to the top. Overall very happy with the quality of this. Lastly I’ll mention, if you’re familiar with Obsessed Garage they only use the absolute best of the best and this is the bucket insert they use. For people familiar with OG you’ll know that’s the best piece of evidence you need to know this insert is legit. ... show more

The best of all
Color: Black
What a great product this is. I finally got around to using it today and I wish that I had one a long time ago. I hadn't used it because it wasn't fitting any of my buckets. So I finally went to Home Depot and bought the orange bucket everybody talks about and it worked perfect. Absolutely perfect. Go ahead and buy one. You'll be glad you did and while you're at it, you might as well buy a couple of those side guards that go into this to rub your sponge or mitt on what a great product those are too ... show more
