This is the Grit Guard, a multi-functional insert designed to fit 12″ diameter buckets. Its primary use is to help keep abrasive dirt, debris, and other crud away from mitts or towels you might use when washing your car.
Loose particulates will fall to the bottom of the bucket, through the grates, and fins at the bottom break up water flow, helping to keep things still and settled.
Drawing your towel or mitt across the top surface can help to extract stuck-on particles.
Chemical Guys says that the Grit Guard can be used for other applications, such as cleaning paint brushes, draining oil filters, or for cleaning car parts, but it’s primarily a car wash accessory.
They say it can fit 3-5 gallon buckets with 12″ diameters. User reviews say that it’s a little too big to fit some 5 gallon buckets, at least at the bottom. You might want to check compatibility before you buy it, or plan to improvise. It looks like the insert can be trimmed to fit slightly smaller diameter buckets.
Chemical Guys sells an optional heavy duty bucket that fits the grit guard, but it sells for $15.
The Grit Guard is available in several color options.
I’ve washed my car by hand before, and it can be tedious. Well, half tedious, half meditative. This looks like it could cut out some of the effort or potential scratches.
I’ve been tempted to order one, and can see the potential for added uses, such as for drying wet mitts or towels.
If you’ve used this, or something like it before, what has your experience been like?
