This Patch-Out version of the Sharp Shoot R Wipe-Out bore cleaner is a stronger cleaner than the original foam/aerosol Wipe-Out and has become quite popular with Benchrest shooters over the last few years. The cleaner is applied to the bore in the traditional manner with wet patches. Nylon brushes can be used to “foam” the product and make it work faster. No actual “brushing” is required according to the manufacturer. Wipe-Out Accelerator will also increase the reaction speed with copper and carbon fouling if applied with a patch before the Wipe-Out Patch-Out is applied. 8 ounce flip-top plastic bottle.
