video Removing stain from the side of the house using Oxiclean.

[+Warwagon MVC]

Want to take the stain off the side of your house? How about 1 1/2 cups per gallon  of Oxiclean. Spray down the side of the house and let it sit. Then come back later and pressure spray it and watch the magic happen.

Looks like wood paneling and a stain is going to soak in deep, in the wood.

 

Sanding or replacement or paint it, is all that will fix that.

That was just the first treatment

One should be careful pressure spraying wood panelling on a house. you damage the surface of the panelling and the water goes deep into the wood. 

 

there's special "house cleaners" you spray or put on the side of the house and leave for a bit before you hose it off with a regular hose, or even just leave on in some cases. 

 

if a stain sticks to the panelling you need to paint anyway as the pain is no longer doing it's job. paint should be thick enough to prevent stuff to soak into and through it, so most stuff, even on raw(rough, not smoothed) panelling and regular rain will get rid of most stuff, a hose and regular cleaning brush should get rid of the rest.

I use a mixture of Chlorine bleach and dishwasher detergent mixed with water.

You might be removing a waterproofing/mould proofing agent that the wood was treated with.

Nope they first started it to remove mold

then your house needs to be stripped of paint, wood treated if necessary, and then painted again anyway. 

 

any professional painter will tell you to not use a pressure washer to clean paint of a wall. sure if you're doing the work yourself and the wood is solid(if it has mold you're probably out on that already) then you can use a pressure washer as a do it yourself replacement, but then you have to wait for several weeks with good sunny weather for the wood to dry properly not just on the surface but all the way in before you can paint it again. 

 

professionals will use some form of sand or media blasting. quick, safe can be done without hurting even soft wood(as long as it's good enough to still be used and don't have to be replaced anyway), and of course it's dry so they can't paint right away.

We are not stripping paint, paint is different, this is 20 years of repealed applications of Olympic cedar tone stain. The siding is solid cedar, which is relatively impervious to moisture because it has a naturally higher occurring oil content.. Pressure washing is acceptable if using the proper pressure setting.

"acceptable" never preferred since it will force water deep into the woods, even on high density and high oil woods. on high oil woods it's even more important to wait untill it's fully dry internally before reapplying anything.
