This big bucket is perfect for washing your vehicle, boat, RV, or ATV. Since many premium shampoos, like Pinnacle Bodywork Shampoo, call for one ounce per 3-4 gallons of water, you need a large bucket to get the proper ratio. The bucket is also perfect for transporting and organizing detailing tools. You can fit a lot of supplies in a 5 gallon bucket! The 5 Gallon Grit Guard Wash Bucket accommodates any size wash tool and holds enough soapy water to clean large vehicles, boats, and RVs. Use our 10 inch Boar's Hair Wash Brush with Telescopic Handle to easily wash big trucks, SUVs and vans. To further protect your vehicle from wash-induced swirls, use a non-alkaline shampoo with adequate lubrication. Wolfgang Auto Bathe is a great option; it will not strip wax and it contains natural oils to lubricate and protect the paint.
