Just got my hands on this parts cleaning brush and wow, it's a game-changer for my garage projects. The stiff polypropylene bristles absolutely destroy built-up grease on my old motorcycle engine. No more scrubbing forever just to see minimal results.

The handle feels solid in my hands - not too heavy but sturdy enough for serious scrubbing sessions. I love that it's PVC so grease wipes right off (unlike those nasty wooden handles that absorb all the gunk).

Used it with some degreaser yesterday to clean some transmission parts, and the brush reached into all those impossible little crevices that normally drive me crazy. The stainless steel ferrule seems durable - no rust or bending like cheaper brushes I've tried.

Only warning: these bristles MEAN BUSINESS. Don't use this on anything delicate unless you want scratch marks. But for heavy-duty metal parts? Absolute perfection.

Bonus discovery: works amazingly on my grill grates too! Way better than those flimsy wire brushes that shed bristles everywhere.
