Hmm. Good idea. Except the print on the bottles is very small... still could probably do it with my Lumix camera.
Ironically, the modern version has something like 30% more fluid than the older one. Which I'm sure would tickle CR all the more. "Thirty percent more of 1/2 strength product means how much???".
Can't recall how much I paid for the 19% Pine-sol, though. I try to keep all my Costco receipts but am not too keen on sifting through ten years of them just to find the one for the Pine-sol. The 8% stuff was purchased recently with a $2.50 off coupon. So the price per ounce of pure Pine-oil might be roughly the same. Had I known I already had a half gallon of double-strength, I'd probably have passed on the 8%. But with Costco I could always return it, if I cared that much about it.
I guess Clorox figured that most people wind up diluting the product with water anyway. And maybe more solvent in proportion with pine oil works better for some applications. Still, with the move to 2x and 3x detergents, wonder if some bright MBA at Clorox will get the idea to come out with an "ultra 2x" formulation that boasts, get this, a 19% concentration and bills it as more economical as well as being more environmentally friendly.
The more things change, the more they stay the same.
