Earlier this year I discovered a new product that’s not only surprisingly effective, but also does more than the manufacturer claims. It’s called Concrobium Mold Stain Eraser, and as the name suggests it’s designed to remove kill mold stains on all kinds of surfaces. It’s completely non-toxic, non-corrosive and has no odour, and it works fast enough that you can see it removes staining. The real surprise is that this stuff is also the best way I’ve ever seen to remove grey, weathered staining from old, exterior wood. If you’ve got an old, bare-wood deck you want to brighten, this stuff is amazing. It’s the best deck wash I’ve ever used.
Preparation Instructions for Concrobium Mold Stain Eraser
The product comes as two powders that you mix with warm water. Let the mixture sit for 10 minutes, then slosh it on your outdoor wood. Without any scrubbing at all, the surface gets bright and new looking. It’s really rather fun to watch. Simply rinse it off when you’re done.
Washing with Concrobium Makes Wood Grain More Vibrant
Unlike every other deck wash or bleach product I’ve used, Mold Stain Eraser leaves the original wood grain patterns vibrant and visible, instead of bleaching the whole surface to blandness. I’m amazed, and after a couple of decades testing products and tools, that doesn’t happen very often.
As frequently is the case with brand new products, store clerks in the big box stores probably have never heard about the product.

Nobody likes to scrub and sand old wood, and I hope this advice gets you up off your knees and onto a deck chair with a cool drink your hand.
