I have a 3 year old deck that was re-stained/sealed last year. Now there is some black mold in spots. The stain itself is in good condition and I do not want to strip it. I only want to remove the mold and then re-seal it. My question is....after I use your cleaner, do I just wait a few days and then seal it? Since I'm not stripping away the stain, do I also need to use the brightner? And..your cleaner won't strip the stain color, right?
THanks for your help!
