​​FREE Recipes or Guidelines

for Soft-Washing & Roof Cleaning



These formulas are general guidelines.  ALWAYS try a test area, FIRST and out of sight.  Ask when the home or building was last painted.  Some soft-washers will not wash a home or building if it was painted under a year ago.  Many soft-washers carry cans of spray paint in white, off-white or gutter touch-up paint to touch up affected surfaces.  Educating your customers prior to providing your service will prevent costly misunderstandings.  For example, algae does not easily adhere or grow on a slick and shiny surface.  Once streaked gutters are cleaned, they may appear not as glossy because the damage occurred to the surface prior to brightening and cleaning the gutters.   Please keep your recipes simple.  Before adding anything to your recipe, EXHAUST yourself finding out whether or not it will negatively react with the sodium hypochlorite or anything else including your equipment.  Just because someone else is posting that they use a certain chemical does not mean that it is safe or that they ACTUALLY use it.   Extremely Important Tip:  ALWAYS take before and after pictures of EVERY JOB including dead plants and previously damaged property or roof tile .  Having photographic evidence of dead plants, property damage, broken tiles or shingles before you arrived or against a dirty home or building prior to providing your services will save you thousands of dollars in replacing plant life or repairs that should not have been your responsibility.

Do you need a fragrance to cover or mask the smell of sodium hypochlorite?  
Do you want to buy it direct from the manufacturer?
Pressure Washer Products is different!  
We were the FIRST ones to carry the sodium hypochlorite stable surfactants.  
Mix the fragrance and a surfactant and watch your savings grow  
Many companies are using fragrances supplied by companies such as Horizon Aromatics, Chemia, Nilum or FloraChem to mix in with surfactants.  
All of the fragrance companies will be happy to sell directly to you.  (We verified your new relationship!)  Cut out the middle man.  Most of the names of these fragrances are going to sound familiar.
Fragrances range from $0.25 to or more per pound.  (Much like high quality perfume and cologne, the more you pay to the manufacturer of the fragrances, the stronger the fragrance may be or better job the fragrance does of masking the sodium hypochlorite odor.)

Tile Roof Washes: 
In a 100 gallon container, thoroughly mix the following:
50 gallons of 10-12% FRESH Sodium Hypochlorite
49 gallons of cool water (NEVER hot water)
8 ounces (1/4 quart) to 64 ounces of Slo Mo Softwash Surfactant

Shingle or Composite Roofs:
In a 100 gallon container, thoroughly mix the following:
30 gallons of 10-12% FRESH Sodium Hypochlorite
69 gallons of cool water (NEVER hot water)
8 ounces (1/4 quart) to 64 ounces of Slo Mo Softwash Surfactant
Metal Roofs: 
In a 100 gallon container, thoroughly mix the following:
20 gallons of 10-12% FRESH Sodium Hypochlorite
79 gallons of cool water (NEVER hot water)
8 ounces (1/4 quart)  to 64 ounces of Slo Mo Softwash Surfactant 
Rinse QUICKLY and hit it with a water based wax or water based tire dressing for a wet look

Neutralize Sodium Hypochlorite:   This topic is fairly simple because all of us studied this in chemistry and in our kitchens or back yards.  It makes the most sense to use water to neutralize SH.  Water is the absolute best neutralization treatment for diluting the salts produced from the SH degrading just about instantly when it is applied to an algal bloom, dirty or hot surface.  Water is inexpensive.  I've studied the internet and found companies selling additives to help protect plants or help them grow when softwashing.  Some products are marketed to help manage SH or salt burns on plants by neutralizing SH with gypsum or weak acids or even 'green' products with fertilizers disguised as neutralizers.  Rinse water should be just water.  Educate your property owner ahead of time and ask them to help protect their plants by turning on the sprinklers or watering the plants/grass that evening and the next few days.  An informed customer is a satisfied and cooperative customer whom will remember the level of care provided by your company.  

We do not suggest any special additive except for Slo Mo Softwash Surfactant or Hang Tite.  BEWARE of these potential dangerous reactions when using corrosive chemicals in your basic recipe.  One of our customers reported that his helper thought he was adding a plant wash to his 100 gallon mix tank and it reacted with the contents blowing the tank lid up about 75-100 feet in the air.  The tank over-flowed and began to melt. 

Beware of sales pitches that push you into believing that Sodium Hypochlorite can be made stronger.  Nothing out there makes SH stronger.  SH stable products, such as Slo Mo Softwash Surfactant or Hang Tite, added to a SH solution will only help your SH recipe 'work' better by bonding to the SH, breaking the surface tension and do a better job cleaning by not running off.   Slo Mo Softwash Surfactant and Hang Tite even help with horizontal surfaces.  Once Sodium Hypochlorite has degraded due to heat, UV rays, organic material or time, nothing can be added to make it stronger.  Get rid of the degraded SH or use it on an application requiring a weaker mix.

Keep your recipes simple.  
House-washing including Vinyl Siding, Brick, Hardie Plank or Siding and Stucco:  Use a watered down version of the roof wash by adding more water and using your soft wash system OR your downstream chemical injector or X-Jet on your pressure washer.  (Downstream injector:  Extend the length of your 1/4" injector pickup hose to allow you to drop it into your roof wash vat.  Most downstream injectors will pick-up a solution that will be up to 20% of your roof wash mix.  Use your 0030, 0040 or 0050 to apply soapy mixtures under eaves many stories up without needing a ladder or yellow noodle extension wand.  X-Jet:  Place roof wash mix in your container and allow the X-Jet to a diluted ratio of your mix to the house.)
If you need to remove a large number of spider webs or eggs that usually require brushing, use a more concentrated version of the House-wash Mix to DISSOLVE the spider webs and eggs.
Irrigation Rust:
(Not for Rust from Metal Rust, Like Chairs or Tables or Rust Stains from Vehicle Radiators) 
Oxalic Acid Powder or Granules 99% (Purchased locally in a 50 pound bag, white powder;  Active ingredient in Rust-Aid) 
Mix 8 ounces up to 1 pound of Oxalic Acid per 1 gallon of  WARM or HOT Water
Add Slo Mo Softwash Surfactant, Hang Tite or Dawn dish soap to use as a wetting agent even for horizontal surfaces
Mix Thoroughly
Use a pump up sprayer to apply to irrigation rust.  When it hits the rust, it should bubble up (similar to using hydrogen peroxide on a flesh wound)
Let DRY completely between coats for best results

Cedar Shingles, Wood Siding, etc. (2 STEPS) 
DO NOT USE Sodium Hypochlorite or Bleach.  Sodium Hypochlorite or Bleach will permanently damage the wood breaking down the cellulose or structure of the wood and remove the natural colors and tones.
     6 ounces of Sodium Percarbonate per gallon (Sodium   Percarbonate purchased locally in a 50 pound bag, white powder)
     1 ounce of Caustic Soda or Sodium Hydroxide (Purchased locally in a 50 pound bag, white powder, granules or flakes)
     Slo Mo Softwash Surfactant
     DO NOT USE SAME SPRAYER FOR BOTH STEPS.  Combination of two chemicals in first and second steps will cause combustion to occur.
     6 ounces of Oxalic Acid Powder or Granules 99% per 1 gallon of  WARM or HOT Water  (Purchased locally in a 50 pound bag, white powder;  Active ingredient in Rust-Aid)
     Slo Mo Softwash Surfactant
Gutter Cleaning:  Streak Lightening: 
Use PWP's Streak Lightening, available in 5 gallon buckets and larger, per Label Recommendations 
Streak Lightening is available in 5 gallon buckets, 10 gal, 15 gal, 20 gal, 25 gal, 30 gal and 55 gallon containers. 
CAUTION:  TriSodiumPhosphate or TSP is a white powder often used to etch the layer of gloss on painted or shiny surfaces and frequently used as a cleaning and degreasing agent in paint preparation.   
Avoid adding TSP to your soft-wash mixes for two primary reasons:
1.  If left to accidentally dry on glossy surfaces such as windows or shiny gutter or garage doors, TSP will cause permanent damage to the shiny surfaces and 'De-Gloss' paint or glass and stain metal and cement surfaces.
2.  Use of TSP will give the possibility of violating the Clean Water Act or CWA.   If evidence of pollution by TSP or other pollutant by your company's services cause a fish kill, waterway plant death, eutrophication of nearby bodies of fresh or salt water, you may be held liable.  It is rare but can cost thousands in fines as warnings are almost never heard of.   Many states only allow the sale of a TSP substitute.  (We strongly disagree with scaring our customers into a sale....we believe in educating them.) 

Two Types of DEGREASING Require Two Types of DEGREASERS:

1.  PWP's Stampede Degreaser:  Petroleum Oil and Greases (Gas Stations, Drive Thru's, Heavy Equipment and Driveway Stains)

2.  PWP's FOG Away:  Fats, Oils and Greases from Food By-Products  (Restaurant Rear Entrance, Barbeque Grill Drippings on Deck, Sun Tan Oil and Restaurant Exhaust Hoods)

Stampede Degreaser and FOG Away Degreaser are available in 5 gallon buckets, 55 gallon drums (larger the container, the greater the savings) and tote quantities at our facility.
