Puracy wiped out a week-old coffee stain in one spray — Blueland needed two and some scrubbing

I had a week-old coffee stain in a mug that I’d convinced myself was now part of the ceramic. Puracy removed it with one spray and a minute of waiting — no scrubbing, no soaking. Blueland needed two sprays and substantially more elbow grease. The gap wasn’t close. If you’re someone who regularly discovers old coffee cups in places you forgot existed, Puracy is the bottle to keep handy.
