What to do about these things...

I am working on my chemicals and pressure on different things, using my own deck, fence, house as lab rats. The vinyl siding is in nasty shape. Lots of holes and cracks and stains here and there, but it does look significantly better after being washed. Things dont appear to have ever been cleaned around here. The concrete up front was black. Literally, black. Covered in algae and mold/mildew. The deck was pretty dark and had lots of algae on it too, altho it wasnt 1/4" thick like it has been on the fence and concrete. The entire place has not been maintained you can tell. I just moved here a few months ago so I am getting it cleaned up.

However. Even using low pressure on the house, it has cleaned up well, Ive tried several things and bleach seems to be the best, although about a cup of bleach and a cup of "knock out" HD cleaner from KO Pressure Supply, Inc. (local company) to a gallon of water works well also. Now then. There are greasy spots on the west side of the house, I'm not sure why. It looks like some Vaseline or something. Bleach didn't seem to touch it, so that will have to be wiped off.

There are also some spots on the east side that seem to be glitter and glue or something. How it got splattered on the house is also beyond me. But the bleach/knock out mixture didn't work on that either. It takes the mold mildew and algae tho. There are some light stains that i don't expect anything to take off especially in the condition that this siding is in.

Also on the front, everything cleaned up well. However when I'm done no matter how much i rinse (with low pressure) mud or something runs out from behind or underneath the lip on the siding in spots and leaves a nasty spot. Does this happen to everyone or is it just due to the lack of maintainence on my house? The only way to stop it will be to wait for it to stop dripping and then wipe it up with a damp rag. It rinses away really easy, even when dry but it comes back, so wiping it up is the only option. Just wanted to know if other people have that problem or not.

Also, on the fence and deck ive tried many things, a lil bleach in a gallon of water, oxiclean outdoors in a gallon of water (quite a bit i might add), purple power, simple green, and now, knock out/bleach mix. No matter what i use, i use a size 8 nozzle which with my 4gpm pump give 1000 psi, i get white fur. Even if I'm no where near the surface with the nozzle. I suspect the lack of maintainece, the cheap wood and the fact that is so freggin old alot of the posts are rotten and the last owner of the place didnt bother to remove the old posts they just put new ones up beside the old ones if that tells you anything about the age and condition of things. The newer sections of fence seem to turn out pretty well with little or fur. The brand new tip i am using is causing some streaking, so i need to get a new one.. again. (THATS why it looked like it had been used before! I brushed it off thinking someone just got the wrong size). I've attached pics. :) You can see some of it needs to be gone over again.

One more thing. What do you do when you come to a power meter on the side of the house like in the pic? If you get the lines wet is it gonna fry you or what. Just try not to touch anything?

Thanks ahead of time guys. Im preparing to get started with my own PW biz :)

First off, stay away from bleach on wood - especially other peoples decks and fences.
I would start off by having a plan. What are you trying to accomplish with the wood stripping it?... and why? After you can answer those questions before you start the work - then decide on the chemicals. The strength and dwell time will definitely play a role. How long you let it set can cause furring, but not let those only components fool you; age or wood, type of wood, and the elements that the wood is subjected to are all other options to consider. Do you know what to do next now that you have furring? What do to next before you seal it.

Your house siding - ok the powerlines in that picture you posted I would xjet around it, touching it will probably lead to a short business life - so DONT TOUCH THE WIRES for god sake.
Use some other chemicals besides those you listed you bought at your home center, too expensive and not strong enough.... also add some SH to your mix, for a 1% application out of the nozzle on your siding. Recommended for your situation and also from the ASA.

Hope that helps - good luck.

The knock out contains HC. It is a concentrate, and if mixed the way they tell you to, will make 128 gallons... but... 1 oz to 1 gallon of water just seems too weak. i used about 8oz to a gallon and a just a few oz of bleach. I guess i could cut out the bleach, just figured in a small amount it wouldnt hurt anything and would just kill the mold and mildew.

Im not trying to strip the wood or anything i just want the mold mildew and algae off of it. In one of the pics you can still see about an 1/8" layer of crap on the wood on the 2x4 going across it. The whole thing was like that. I'll have to hit it again i just want to get my procedure down before i run out of things to do on my own fence.

Overall I was happy with how stuff turned out. Im going to try some other stuff tho still.

Sorry its not HC, its Sodium Hydroxide that it has in it. Also says it has Nonionic Surfactants, and Sodium Metasilicate .
