Ok, here's the job we did today. DEFINITELY a learning curve on this one. Thought I'd share my experience.

First job with the new SWS skid.

First off, I hit with a 2% mix of CH. Strained through a paint sock and basket strainer. I had no CH leftover in the basket after I ran water through. (Don't know if that's supposed to happen, but it did to me.)

Added GW a little on the heavy side since it was a 14/12 pitch. Non-walkable.

The thick cedar shakes GUZZLED the solution. I hit the whole thing 2x.

The job took me 8 hours from start to finish. If I were to do it again tomorrow - it would take me 6.

I didn't realize the battery on the SWS cradle skid would die so quickly - I only had one. I have used my old Pressurewashstore.com special pump for 3 days on 1 battery charge, but the SWS skid motor eats batt juice for breakfast! So I had to go and buy batteries in the middle of the job. Also realized later that I didn't need to beach wash until the end of the job. I was doing one zone at a time, then bleach washing immediately after. Wasted a ton of time doing that.

I am going back tomorrow to scrub/wash 3 skylights and a window (probably a gutter or two as well). They have terrible CH residue splatters on them, despite my best attempts to keep them rinsed constantly. I had less problems with CH residue this time, but still need to dial it in.

Maybe I'm crazy for doing this, but I used my 100 gallon tank to "one-batch" my CH. I had the 100 lb pail of CH and mixed in the amount for each load. Then, once I realized I bought the wrong venturi style hose end sprayer for my bleach wash (not enough flow to stream tip the top of the roof) - I loaded my 50 gallon tank with BW mixed.

It seemed to work pretty well, except for the time it took for the bleach to clear the hose and switch to BW and back again. But on the upside it was SUPER easy to simply run my 50 gallon tank through my system at the end of the day, wash down the truck and leave it in there to keep it bleach neutral.

Anyone else do this? Am I crazy to lean toward keeping BW in my 50 gallon tank permanently??

Overall, I was impressed with the total clean results about a 7 out of 10. There was still a lot of staining and spotting on the cedar that it didn't seem to cut fully - especially when you got up close (see pics). Homeowner was happy, but I told her I'd still come back in a few weeks and check on the progress and re-treat if it wasn't coming as clean as I'd like. I'm pretty anal about how something looks with my name on it. I want it to look AWESOME. When I was done - it just wasn't quite there.

Anyways, hope my experience helps someone new out there someday.
