Frequently Asked Questions
Where Are Psycho Wrench Products made?
Psycho Wrench products are made by hand right here in the USA down in Texas, where the sun’s hot, engines are loud, and we don’t fake a damn thing. Packed with American grit and a touch of chaos.
How often can I use the Knuckle Scrub Down Soap?
Use it anytime your hands are dirty, or you just need to freshen up. Grandma always said, you can never be too clean. “Don’t Be A Heathen!”
Why we use no chemicals?
We’re not trying to slam other brands; we’re just calling it like it is. Most products out there are loaded with synthetic fillers that wreck your skin, and leave behind more problems than they solve. We got tired of that noise. So, we built Psycho Wrench with clean, high-performance ingredients that work. No gimmicks. No chemical garbage. Just a solid, all-natural formula that keeps your hair healthy and strong.
