So today, I cleaned my first deck. It was at my sisters new house ( she bought it from a family member) I wish I took some before pictures, I meant too but I just got caught up and forgot. The deck was extremely neglected. The deck hasn’t been maintained in at least 10-12 years, it was extremely black and green and some parts were nice and fuzzy from all the moss. The deck looks 10x better then when I started. It came out very well but not perfect as I was hoping for. Here are some of the issues i encountered, It looked like some of the wood started to fur up, I’m not sure if that’s from the SH or something else. Problem 2 As I’ll show you in a picture there were some white spots on some of the wooden banisters. I’m not sure what they are from or how to remove them. Also on some of the top rails which are clean it look like some areas are still stained green. It wasn’t coming off with pressure or the first application of SH. Should I just hit it with another coat of SH? The biggest problem for me was it took forever to rinse all the banisters, on all sides and in between them. Once it dried I notice there were
Some spots I missed. I’m pretty sure I hit those areas when rinsing. Do I need a second coat or is it normal to not get every bit of green gone.?
My process: I wet the entire deck,
Soaked everything. Then I DS straight 12.5sh and a little bit of elemonator my DS is about 10-1 at 4gpm I let the SH dwell for about 15 minutes and than I rinsed with medium pressure. After I rinsed, I X jetted Oxalic Acid I let that dwell for 10 minutes and than lightly rinsed. The first picture is after the deck dried. The second is the banisters and the third is just after I rinsed the OX off.
