The Ultimate Car Wash Bucket from Griot's $44.99. Sounds like overkill? Maybe, but it does what it supposed to do and sure beats a leaky sheetrock slurry bucket. From the seller:
This truly is the Ultimate Car Wash Bucket. Here are five important and unique features that I think you'll appreciate... It has a lower grill so the heavy debris sinks to the bottom and won't allow your wash mitt to pick it up again. There is a molded-in measuring cup (patented design) in the grill for you to dispense the proper amount of Car Wash each and every time. No more guessing, no more wasting product. The top sieve allows your wash mitt to lay on it without dripping over the side. 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 hash marks in liters and gallons on the inside wall, and has a wonderful form-fitting handle. The bucket is 19" wide, 9" across and a generous 9" deep. The snap-on lid keeps the water from splashing during transportation. The most well thought out wash bucket on the planet. Enjoy the best!

The Most Important Step In Proper Exterior Car Care Is A Safe And Thorough Cleaning
This is the MOST important step for paint preservation, yet many people overlook this crucial element when caring for their finish. Many of the mild scratches you see in your finish are from aggressive washing. The dirt acts like sandpaper, scratching the finish while you're rubbing the surface of your vehicle. Be gentle while washing, and frequently rinse out your mitt or brush during the cleaning process. With Griot's Car Wash, the first thing you'll notice is how slippery it acts between your wash mitt and the paint. This is an important characteristic of our Car Wash and contributes to its ability to lift away contaminants while protecting the finish during your washing therapy. Griots Car Wash is gentle on your wax, yet removes more dirt and road grime than any car wash I've tested. Safe for all paints. We've included a unique measuring scale right on the 16 ounce bottle's label and an easy pour spout to reduce waste. Save some money, buy it by the gallon, and refill your bottle. Our Car Wash is environmentally friendly too.
