Haven't tried it. It looks from the product info like a citrus equivalent of the vegetable oil-based Gunzilla cleaner. Gunzilla's acquired an enviable record in the sandbox for improving functional reliability. I find it one of the best carbon cake softeners going. Like PrOlix, it also dries to leave a thin lube film behind that is not wet at all. It also penetrates super effectively for getting under copper and lead to make them easier to brush out, or even for loosening rust. It's also non-toxic.
Like PrOlix, Gunzilla also is not a copper solvent, though the company now makes a companion product that is. It's for those not wanting to wait for penetration to loosen deposits.
