Converting the sprayer to a chemical applicator
Items needed:
1. Fimco 8 Gallon chemical sprayer. May be purchased at agriculture or home and
garden stores or the internet (search word: Fimco 8 gallon sprayer). ($140)
Advantage: it rolls and has rechargeable battery
Disadvantage: only holds 8 gallons, pump is 1 gallon/min.
16 gallon sprayer offered by Northern Tool.
Advantage: holds 16 gallons, has stronger pump @ 2.2 gallons/min. can
accommodate 100+ ft. of hose.
Disadvantage: no wheels, has battery clamps but no battery, requires 12V lawn
mower or jumper battery
2. Seventy-five feet of garden hose. ($20)
3. Hose nozzle ($2)
4. 30 feet (80 feet if using NorthStar tank) 3/8", chemical resistant braided hose. ($10)
5. 4 each small hose clamps for braided hose. ($2)
6. 1 each 3/8" plastic barb coupling (.50)
7. 2 each 1/4" plastic male pipe to 3/8" barbed adapter (.50)
8. 1 each 1/4" female quick connect, 1/4" female pipe threads ($5)
9. 1 each 1/4" male quick connect coupling, 1/4" female pipe threads. ($3)
Building Instructions for chemical applicator
Convert the garden sprayer to a house washing machine.
1. Cut the curly hose off the back of the sprayer, leaving about 6" to reattach the
braided hose.
2. Connect the braided hose to the 6" hose on the sprayer using the 3/8" barbed
fitting and 2 hose clamps.
3. Cut off and set aside, for later use, about 6" of the 3/8" braided hose.
4. Insert the plastic male pipe to barb fitting into the braided hose and secure with a
hose clamp.
5. Screw the female quick connect to the barbed/pipe fitting above
6. Remove the curly hose from the spray gun and replace it with the 6 " braided hose.
Secure with hose clamp.
Note: You may wish to purchase a higher end spray wand that accepts these
nozzles (80 degree, .08)
7. Insert a male pipe to barbed adapter into the other end of the 6" hose and secure
with a hose clamp.
8. Attach the 1/4" male quick connect coupling to the 6" hose.
You have finished converting the garden sprayer to a house washing machine. The
reason for the quick connect is for attaching an extension wand when needed.
Steps 4-8
Making an extension wand
Build a 10 foot extension wand for reaching upper areas of house without the need of
a ladder.
Ultimately, the wand will look like this (S shaped):
Items needed:
1. 10 foot section of thin wall metal conduit (EMT) purchase at hardware or electric
supplier ($4)
2. 3/8" threading tap ($5)
3. one 3/8" ball cock, female pipe threads ($5)
4. two 3/8" close nipples ($1.50)
5. two 3/8" x 1/4" bushing ($1.50)
6. 0ne male 1/4" quik connect coupling ($3)
7. one nozzle assembly as shown below (found at agricultural supply stores or
internet). TeeJet is one brand name ($18)
3/8" male Body
80 degree .08 nozzle
Building Instructions for extension wand
General: use Teflon tape on all joints.
1. Tap 3/8" threads in both ends of the 1/2" EMT
2. insert the close nipples into each end.
3. Using a pipe bender or similar device, make a 45 degree bend within 1 foot of each
end. The bends should oppose each other to form an elongated S.
4. At one end install the ball cock and quick connect coupling.
5. At the opposite end install the nozzle assembly.
Using the quick connect fittings install on the sprayer hose, you may easily switch
between an extension wand and a short wand as you work your way around the job.
Total cost of extension wand: about $29
The chemical formula
Be sure to read and understand. Using the correct chemicals and mixture ratio
is the key to making your business successful.
The amazing house washing machine is designed for washing wood, stucco and vinyl
siding and many other items, such as awnings and yard furniture. These items should
never be cleaned using high pressure.
Before starting any cleaning job, check the weather. The temperature should be at
least 55 degrees. Cold temperatures retard the cleaning action of chemicals. In fact
they may not work at all. The warmer, the better.
If using a Fimco sprayer, the battery charge is good for about 5 refills before requiring
a recharge. Five refills will clean approximately 8000 square feet of siding (3-4
average sized homes). If you feel you’ll need more than 5 refills for the day, plug the
charger in during breaks, lunch or whenever an electric outlet is convenient.
After using the sprayer, run clear water through it to flush any chemicals.
Chemical recipe:
“It’s in the process, not the pressure”. The chemicals you will be using will do the
cleaning for you.
One gallon of mixed solution will clean approximately 200 sq. ft. of surface.
To determine the amount of solution to make use the following formula:
Area to be cleaned / 200
1400 sq.ft./200 = 7 gals.
The basic formula is:
3 oz. AllClean House Wash, plus 8 oz. concentrated Clorox per 1 gallon of water.
Example: Fill the tank with 7 gallons of water then add 21 ounces (about 2-1/2
cups) of AllClean House Wash and 56 ounces (7 cups) of chlorine bleach.
Stir the solution a couple beats and your ready to start washing.
Note: We highly recommend Clorox brand, as the cut-rate brands traditionally
do not have the brightening ability and shelf life of Clorox. You may wish to experiment
with other brands; however, most cleaning contractors are in agreement with us.
Another note about chlorine bleach: Clorox and similar bleaching products are
solutions of water and sodium hypochlorite. The sodium hypochlorite is the bleaching
agent, which over time breaks down and forms water and sodium chloride (table salt).
Generally, the product has a shelf life of about 6 months if left in an unopened original
container. However, once the product is removed from its container and diluted in a
cleaning solution, its effectiveness as a bleaching agent diminishes dramatically; in as
little as 24-48 hours. Therefore, do not make more solution than you will use during
any single day.
A third note about chlorine bleach: Bleach does not clean. It brightens. White clothes,
washed without bleach will be clean, but they'll also be dingy. So, if you want a clean
dingy house, don't use bleach. Also, bleach in a concentrated state is less effective
then diluted bleach in solution. Therefore it is not necessary nor advisable to ever mix
bleach at concentrations greater than a 10:1 ratio (10%). Our mixing instructions
above allow for a 16:1 ratio (7%) of chlorine bleach. By following our mixing
instructions the final cleaning solution will contain less than .2% (that’s
less than 1%) sodium hypochlorite.
About AllClean House Wash
Over the years we have tested and used many, house washing products, all claiming
to be the best on the market. Unfortunately, only one product can be best on the
market. In 1995 we discovered it. This product has consistently out preformed (by a
long shot) any we have used. In fact, we found it so effective that in order to keep it
away from our competitors, we have had it privately labeled, with our company name.
We can do the same thing for you.
It is, indeed, unusual to find a cleaning product that is merely sprayed on and rinsed
off with low pressure, taking dirt, mildew, spider and bug droppings and other stains
with it. Our house wash even emulsifies spider webs; other cleaners won’t touch a
spider web and a 4000 psi pressure washer won't do more than knock them around.
The cleaner is safe and effective on most all surfaces: vinyl, wood, paint, cloth
awnings, metal, lawn furniture, even boats.
Precaution: windows should be rinsed thoroughly, as the cleaner may leave a
film if left to dry.
When you finish the job, stand back and watch it get brighter. You and your customer
will be blinded by the results.
AllClean House Wash is available in case lots (4 gallons per case). One gallon of
AllClean House Wash concentrate will make 40-50 gallons of cleaning solution. One
case contains enough concentrate to wash over 35,000 square feet or about 20
average sized homes.
Wish to have your chemicals privately labeled?
We can do it for an order as small one case.
How to properly wash siding
“It’s in the process, not the pressure!”
There is no need to blast the side of a house with 3000 psi. In fact, pressures
washers leave streaks, break window seals, put hash marks on wood, force water
under the siding and defoliate plants. Pressure washers have a place; cleaning
driveways, cleaning construction equipment and cleaning decks, but not siding. If
you insist on using a pressure washer, it is best to use it for rinsing only. Reduce the
pressure to only a couple hundred pounds by adjusting the regulator valve, unloader
or using a larger nozzle, such as a chemical tip. The chemical injector of a pressure
washer may also be used to apply the cleaning solution, but be forewarned, you will
use an excessive amount of chemical, thus driving your job cost up.
Place your machine so you can wash one side of the house at a time then begin
spraying the siding from the bottom up. If you spray from the top down, clean
streaks will appear on the siding, and you don’t want that to happen.
More than likely you will not be able to reach the eave or soffit without using your
extension. Therefore, the quickest way to perform the job is to spray and rinse the
bottom half, going completely around the house, then attach your extension and go
around a second time to get the top part. Again, apply the chemical from bottom
up. Sorry, some house may require a ladder.
The chemical should have a dwell time, ideally, of about 5 minutes. However, the
chemical could begin to try quicker on a hot sunny day. Do not allow the chemical
to dry before rinsing. Let it dwell as long as possible but rinse before it dries. This
means you will have to spray and rinse sections at a time.
The siding should be rinsed from the top down, with the garden hose using street
pressure. You will be amazed as the dirt, mold, webs and stains disappear before
your eyes with just a souped-up garden sprayer and a garden hose.
Remember the rule: Apply chemical bottom up, rinse top down
When you’re finished, rinse your machine with clear water, pack up your stuff, collect
your money and go to the next job.
