I won’t rehash the details of the wine stain remover story I wrote for Wired earlier this year. Suffice it to say that StainRx is a late comer to the party, and they submitted a product to me well after that piece already ran.
Long story short, I put StainRx up against Chateau Spill, my hands-down winner in extensive testing, to see which was best. The results: With a shorter-term wine stain (setting for a few hours before treatment), StainRx was slightly ahead. On the tougher longer-term stain (which I let set for 24 hours), Chateau Spill was the marginal winner. All told, it was about a draw.
Now my hunch is that StainRx — which is marketed primarily as a “blood strain [sic] remover” — is basically the same chemical as Chateau Spill, which is a lab-grade solvent designed to get dye off of scientists’ skin. StainRx looks, smells, and behaves almost the same way, so I figure you’re really getting the same stuff here as in Chateau Spill.
The company says about its product: “We do sell our product in bulk for others to repackage under their label and we repackage for others as well. For over 50 years our product, Erado-Sol has been sold to hospitals, labs and doctors’ offices to remove chemical and biological stains. Approximately 10 years ago we made our laboratory tested product available to the consumer under the name Stain Rx. The product is sold in Spring Fresh Scent and Fragrance & Dye Free solutions.”
Is Chateau Spill the same thing? It’s just a hunch, and there’s no real way to know for sure. I suspect the differences in performance were due to slight variations in the amount of wine that made it onto my test fabric, and the fact that you basically have to douse the product with a nozzle from the StainRx bottle rather than gently spray it on as you do with Chateau Spill. It’s a lot easier to control the amount of product you’re using with Chateau Spill, and you’ll much more quickly go through a bottle of StainRx because of the amount that comes out with each application. (StainRx also makes single-use wipes, which I didn’t test due to their generally limited size.)
At $18 for a 16 oz. bottle, StainRx is cheaper per oz. (by about half) than Chateau Spill, but you’ll use it faster. Which is ultimately a better value? Hell, ask Mathhacker.
