Professional Guide to Evolving Elements House Wash Mix

Professional Guide to Using Evolving Elements House Wash Mix

Evolving Elements House Wash Mix is designed for professional exterior cleaners who want predictable, repeatable results on Australian homes. This guide explains when to use it, how to dilute it, how to boost it with sodium hypochlorite (SH), and how it compares with High Grip Soap and Surfactant Soap.

What Is Evolving Elements House Wash Mix?

Evolving Elements House Wash Mix is a professional-grade softwash additive formulated specifically for Australian conditions. It is designed to:

  • Increase wetting and penetration on painted surfaces, cladding, eaves and gutters
  • Generate stable foam for visual coverage and dwell time
  • Lift organic soiling, traffic film and general grime
  • Work effectively as a stand-alone detergent or as a booster with SH
  • Rinse clean without leaving heavy residue when used as directed

Unlike generic dish soaps or hardware-store detergents, House Wash Mix is built for the real world of house washing: mixed into tanks, run through pressure washers, downstream injectors or proportioners, and used on a variety of substrates in changing weather.

When Should You Use House Wash Mix?

Use House Wash Mix whenever you need controlled foam, improved cling and better cleaning than plain water and SH alone can provide. Common applications include:

  • Standard house washes: painted weatherboards, render, Colorbond fascia, eaves and soffits
  • Pre-wash on dirty homes: break surface tension so your SH can penetrate evenly
  • Rinse assist: help lift loosened soil and surfactant residue off the surface
  • Non-SH cleaning: light dust, cobwebs and atmospheric grime where you do not want to use SH

For highly polished, very sensitive, or specialty substrates, always spot test first and follow your own site-specific risk assessment.

House Wash Mix vs High Grip Soap vs Surfactant Soap

Evolving Elements offers several surfactant systems for different tasks. Here is a simple comparison to help you choose the right product for each job.

FeatureHouse Wash MixHigh Grip SoapSurfactant Soap
Primary UseGeneral house washing, pre-wash and SH boostingMaximum cling for steep roofs, verticals and high dwellHigh-dilution surfactant for economical bulk cleaning
Foam LevelModerate to high, easy to see coverageVery high, thick “grippy” foamModerate, efficient rinsing
Cling / Dwell TimeBalanced cling for walls and eavesMaximum dwell on roofs and stubborn areasLower cling, faster release and rinse
Typical Use With SHYes – designed as a house wash boosterYes – especially for roof cleaningYes – where high dilution and economics matter
Typical Dilution (Detergent in Mix)Stronger than Surfactant Soap, milder than High GripMore concentrated per litre of solutionHighest dilution ratios, very economical per job
Best ForEveryday house washing, balanced performanceRoofs, heavily soiled facades, stubborn traffic filmLarge areas, price-sensitive work, maintenance cleans

If you primarily wash roofs and want extreme cling, consider pairing High Grip Soap with SH. For large, frequent jobs where economy is critical, Surfactant Soap at high dilution is often the best choice. For the majority of standard house washes, House Wash Mix offers the right balance between performance and cost.

How House Wash Mix Works (In Simple Terms)

House Wash Mix is built around professional surfactants and wetting agents. On the surface, it does three main things:

  1. Reduces surface tension: This allows your solution to spread out, penetrate surface pores and contact more contamination instead of beading up and running off.
  2. Forms controlled foam: The foam acts as a visual guide for coverage and slows the run-off, giving your chemistry more dwell time to work.
  3. Helps lift and suspend soil: Loosened dirt, oils and organic residue are held in solution so they can be rinsed off rather than re-deposited.

When combined with SH, House Wash Mix helps deliver the oxidiser evenly, improves cling, and reduces the likelihood of “zebra stripes” and missed patches.

Dilution Guidelines for House Wash Mix

These dilution guidelines follow the official Evolving Elements ratios: 1:25, 1:50 and 1:75. The charts below show the approximate amount of House Wash Mix required per 20 L batch.

1. Dilution Without SH (Detergent-Only Cleaning)

Use these ratios when you want to clean light grime with no sodium hypochlorite, for example maintenance cleans or sites where oxidisers are not desired.

Soiling LevelRatioHouse Wash Mix (per 20 L)WaterExample Use
Light dust / cobwebs1:75~260 mLTop up to 20 LMaintenance wash, lightly soiled façades
Standard grime1:50~400 mLTop up to 20 LGeneral house washing, fascia, eaves
Heavier grime (no organics)1:25~760–800 mLTop up to 20 LDirty exteriors requiring a stronger detergent load

Apply, allow a short dwell time, gently agitate if required and rinse thoroughly. Adjust these guidelines to match your equipment and your own field experience.

2. Dilution With SH (Boosted Softwash)

Use these ratios when House Wash Mix is added to sodium hypochlorite (SH). The detergent ratio remains 1:25, 1:50 or 1:75 – you simply adjust your SH volume according to the level of organic growth and your local requirements.

Soiling LevelDetergent RatioHouse Wash Mix (per 20 L)SH (approx. 12.5%)WaterExample Use
Light organic growth1:75~260 mL2.0–3.0 LTop up to 20 LLight mildew, shaded walls
Moderate organics1:50~400 mL3.0–4.0 LTop up to 20 LStandard house wash with organic staining
Heavy organics*1:25~760–800 mL4.0–6.0 LTop up to 20 LSevere mould, mildew and heavily affected surfaces

*Always confirm substrate compatibility, avoid application during high heat or strong wind, and prevent the solution from drying on the surface. Adjust SH levels to meet local regulations and your own method statements.

Step-by-Step Application Method

The following is a general workflow for using Evolving Elements House Wash Mix as a boosted softwash solution with SH. Adapt to your own equipment and safety procedures.

1. Site Assessment and Safety

  • Walk the property and identify sensitive plants, oxidisable metals, stripped coatings and potential water ingress points.
  • Check weather conditions – avoid high wind and strong direct sun where possible.
  • Wear appropriate PPE: gloves, safety glasses, suitable footwear and clothing.
  • Confirm drainage paths and avoid run-off into stormwater where regulations require containment or control.

2. Mix Your Solution

  • Decide whether you are working with detergent-only or SH-boosted solution.
  • Measure House Wash Mix into your tank according to the selected ratio (1:75, 1:50 or 1:25 for a 20 L batch).
  • Carefully add SH if using it, following your handling procedures.
  • Top up with water to the required volume, recirculate or gently stir to ensure an even mix.

3. Protect Surroundings

  • Wet down surrounding plants, lawns and any sensitive surfaces before application when using SH.
  • Cover or mask items that cannot be exposed to SH or cleaners.

4. Apply the Solution

  • Apply from the bottom up on walls to reduce streaking, using your softwash lance, low-pressure system or pump sprayer.
  • Aim for a uniform, foamy layer – House Wash Mix should give clear visual coverage.
  • For heavily soiled areas, slightly increase dwell time, but do not allow the solution to dry on the surface.

5. Dwell Time and Agitation

  • Allow a typical dwell time of 5–10 minutes depending on conditions.
  • On stubborn spots, gently agitate with a soft brush or pad.
  • Reapply lightly if sections start to dry, especially in hot or windy weather.

6. Rinse Thoroughly

  • Rinse from the top down with low to moderate pressure, avoiding damage to paint, sealants or cladding.
  • Rinse plants and surrounding areas again after cleaning when SH has been used.
  • Check for streaks or missed patches and spot-treat if required.

Performance vs Cost: Is House Wash Mix Worth It?

Some contractors look only at the detergent purchase price per litre, but the real question is: how much does each clean cost you in chemical, time and call-backs?

House Wash Mix is formulated so that:

  • You use a controlled dose in your tank mix, rather than guessing with generic detergents.
  • The foam helps you see exactly where you have been, reducing missed areas and rework.
  • The improved wetting and dwell can reduce the number of passes required.
  • Consistency from job to job improves your reputation and reduces complaints.

In many cases, the slightly higher purchase price of a purpose-built product like House Wash Mix is more than offset by reduced time on site, smoother workflow and less risk.

Frequently Asked Questions

Can I use House Wash Mix without SH?

Yes. For light grime and general exterior cleaning, House Wash Mix can be used as a stand-alone detergent. Use the detergent-only dilution table as your starting point and adjust from there.

Safe Work Australia

How does it compare to just using SH and water?

SH and water alone can work, but they often have poor wetting on some surfaces, run off quickly and can be patchy. House Wash Mix improves coverage, dwell and rinsability, and gives you visual confirmation of where the solution has been applied.

Is House Wash Mix safe on all painted surfaces?

It is designed for use on sound exterior coatings when diluted correctly and rinsed thoroughly. As with any chemical, always spot test first, especially on oxidised, aged or failing coatings, and avoid high pressure that can damage paint.

Can I use it on roofs?

You can, but for steep or very dirty roofs, High Grip Soap is usually preferred because it provides maximum cling and dwell. House Wash Mix is optimised for general wall, fascia and eave washing.

Does House Wash Mix contain fragrance?

The exact fragrance and surfactant blend is tuned for professional use. Check the current product SDS and TDS for detailed information and always follow label directions.
