Before you start shooting high pressure water at a house there is one vital thing you should know… Please don’t place your tip close to the windows when rinsing. Always keep your tip at least 4 feet back from all glass because anything closer can result in hurt. If you have double-pane windows you should be back at least 5 feet and may want to consider just using the garden hose to rinse them off. They are known to sometimes get added condensation between the panes if the difference in temperatures are just right.

One more thing… that detergent we mixed up has some chlorine in it so we must ensure that any over-spray doesn’t hurt your plants and shrubs that may be around the house. We do this by first spraying straight clean water onto all the plant life. This is something that we have to do through-out the job, so don’t forget.

OK, now that we covered all that, let’s get started.

As I was saying before, we want to start at a corner of the house and do sections at a time, especially in the hot summer sun where the hot air will tend to “bake” our detergent onto the surface.

So with the machine now running and our siphoning hose in our container of detergent already we will start to spray our mixture into the open air away from everything until you start to see a foaming substance coming out or you can smell the chlorine that is in the mix. At that point it’s time to apply it onto the first section of wall. The best place to start is at the bottom corner, working your way up to the top using a back-and-forth motion from side-to-side. The wand should be directed back-and-forth at a rate in which there’s plenty of solution applied to the surface. Keep doing this until you’ve covered a section of about 20-24 feet wide (12-16 feet if it’s being done on a hot sunny day).

Once that’s done, we will now be switching tips and rinsing the detergent off. You may switch the tips out without shutting the machine off as long as the trigger is not being pulled. (switch to your white 40 degree tip when rinsing)

When rinsing, start back at the end in which you started applying the soap. Instead of doing it from the bottom up, you will want to start from the top down. Use the same type of motion as before, but a small slower making sure that you rinse thoroughly and that you get any spots that may need a small extra attention. Just make sure you are no closer than 16 inches from the surface. And remember NOT to get that close to windows (4 ft. minimum distance).

Well, that’s really all there is to doing a house-wash. To complete the rest of the task just follow the same instructions as above until the whole house is finished. If you get to a section that you can’t reach with your wand, just take the tip off and add that extension rod to the end of the wand along with the tip you were using and you should have no problem doing the job as plotted.

Please Note: You will feel more backlash from the wand now that you’ve added more length to it, so be careful with your actions.

If you noticed a few areas need to be touched up with detergent and re-rinsed, just do it while you are in the area before you go to the next section.

When you have really completed the task, be sure to rinse the chemical injector with clean water before storing the unit away until next time. The way this is done is the same way you pulled detergent through it. Set up a 5 gallon bucket in place of the detergent container and let the machine draw the water through the whole system until the bucket is empty. Use a minimum of 3 gallons of clean water and remember that the soap tip must be used to accomplish this.

If you have an ancient masonry surface such as concrete, brick, or stone that looks really green, black or both I am going to share with you how you can clean them up.  There are various methods for each surface type so I am going to discuss them all.

First you have to gather the equipment needed to complete this task.  You are going to need a empty 5 gallon pail, stainless steel bug sprayer, access to water with a hose, muriatic acid or some other masonry cleaner, a scrub brush, steel wire brush, protective gear waterproof gear, gloves,jacket, hood, pants, boots and most importantly eye protection, acid does not feel excellent in your eyes.  Lastly you will need a excellent gas powered pressure washer you can buy one for around 0.00 or just rent one for a day.

Dirty brick and stone walls can be handles a few different ways you can use muriatic acid or a less perilous cleaner such as sure clean or a pressure washer or both together.  If you opt to use a cleaner wet the surface first with a hose.  Next apply cleaner with a hard plastic bristle brush or use the bug sprayer to apply it.  Be sure to dilute the cleaner with water first to make it safer to use, follow the instructions on the cleaner you are using.  Try not to breath in the fumes from the cleaner either, it can make you very dizzy and vomit.  In really dirty area you may have to scrub really hard or use a steel wire brush moderately over the affected area.  If you are using acid it should bubble up on dirty area straight away but it doesn’t work all that well on moss.  After you have scrubbed the wall down hose it off or I recommend using a pressure washer with the fan tip to clean it off.  A pressure washer itself is capable of cleaning most of the surfaces if done properly, but don’t get too close with the tip you blast a hole in your brick or mortar joints if they are aged.

If you are cleaning concrete it can be done much the same way as what you did  the brick and stone wall.  But you must be more consistent with your pressure washer.  If not you will easily see where you have wash and where you have not sometimes giving your concrete an hideous striped look.

If you have an ancient sandstone surface such as a porch or steps that are flat there is another method you should use to clean them.  For this project you will need a rubbing stone or another piece of sandstone that is about the same hardness.  This does require some back breaking work but you will be very pleased with the results when you are done.  Take your rubbing stone a rub it all over the surface till you get a nice sandy grit all over the surface, in dirtier area you may have to scrub a small harder.  Once complete simply sweep the surface or wash it off with a hose. Do not use acid or a pressure washer on sandstone surfaces, they are very easily hurt.

If you are unsure of how to complete this task you should hire a qualified mason or pressure washing contractor to take care of this for you.  Working with acid and pressure washers can be perilous for both you and the people around you.  If you are not careful you can easily hurt surfaces if you do not clean them properly.
