This truly is the Ultimate Car Wash Bucket. Here are five important improvements over the last one that I think you'll appreciate... We now have a lower grill so the heavy debris falls to the bottom and won't allow your wash mitt to pick it up again. There is also a molded-in measuring cup (patent pending) in the grill for you to dispense the proper amount of Car Wash each and every time. No more guessing, no more wasting product. We have also redesigned the top sieve so that your wash mitt can lay fully on it without dripping over the side of the bucket. The 2" casters are included so you can push the bucket around with your foot if your hands are full. The heavy-duty molded plastic tub holds a massive six gallons of water, has a wonderful form-fitting handle, and has measurements in liters or gallons on the inside wall. The bucket is 19" wide, 9" across, and a generous 9" deep. The snap-on lid keeps the water from splashing during transportation to the wash site or seals out dust when storing your washing supplies. The most well thought out wash bucket on the planet!
