The Story
Living in Miami Beach means living with humidity. And humidity means mold in the bathroom. I could have called maintenance, waited 3 weeks, and had someone spray the same stuff I can buy for $10. Instead, I bought Moldex.
It works. Spray it on, mold dies, wipe it off. But the RMR-86 has 42,000 reviews and people post before/after photos that look like magic. It literally removes the stains in seconds. The Moldex kills the mold but doesn't remove the staining as fast.
For $5 more, the RMR-86 is the move. But honestly, at $10, the Moldex got the job done. This is one of those 'both options are fine, I just want the satisfaction of watching mold disappear in 15 seconds' comparisons. Sometimes the research nerd in me wants the optimal solution even when the adequate solution is sitting right there working perfectly fine.
The Lesson
In Miami, mold spray is not optional. It's a lifestyle product. Budget accordingly.
