Rated 5 out of 5 by Anonymous from Highly recommend for Mildew blocker and cleaner I love it! It immediately takes off any traces of mildew without scrubbing. Any spider poop comes off easier after this has been put on also. I will definitely be keeping this on board!!

Will this work on “pink mold”

Asked by: Outlookdon

Hi. 303® Mold & Mildew Cleaner + Blocker works very nicely in removing these types of stains. However, if the stain has deeply penetrated the surface, perhaps a stronger product or method may be needed. Once the stain has been successfully removed, 303 MMCB would prevent the stain from coming back. Hope this helps!

Can this be used on an outdoor rug? Also, I'm interested in the 303 fabric protectant afterwards, as well as something to prevent cushions from fading in the sunlight. Would that be the aerospace protectant? What should I use on my metal patio furniture?

Asked by: LASP

Yes, 303 Mold & Mildew Cleaner can be used on an outdoor rug. As far as the cushions you can use 303 Fabric Guard to add or extend water repellency and stain resistance, while prolonging the original UV resisting of the fabric. On the metal parts, we recommend looking into our 303 Speed Detailer. Hope that helps!
