Soft Washing Equipment: The Ultimate Guide for an Effective Clean

By Mark Cave December 23, 2023

Soft Washing Equipment: The Ultimate Guide for an Effective Clean

Soft washing is quickly becoming the preferred cleaning method for homeowners and professionals alike, replacing the traditional high-pressure washing due to its superior effectiveness and gentler approach. If you find yourself asking, "What Is Soft Washing, And How Does It Work?", you're not alone. Let's delve into the intricacies of this revolutionary cleaning technique.

Understanding Soft Washing

Unlike high-pressure washing, soft washing uses a combination of low-pressure water and specialised chemicals to clean away dirt, algae, and mold from surfaces without damaging them. The art is in the chemicals used, not in the force of the water.

Essential Soft Washing Equipment

Quality soft washing equipment is just as important as the technique used. Ensure that you invest in the right tools to get the job done effectively. Here are a few essentials:

  1. Low-Pressure Pump
  2. Soft Wash Gun
  3. Soft Wash Nozzles
  4. Chemical-Resistant Tubing
  5. Tanks and Reels

Choosing the Right Chemicals

Professional-grade soft wash chemicals are designed to tackle specific surface contaminants. It's crucial to make the right choice to ensure the effectiveness of the washing process. For instance, sodium hypochlorite is a popular choice for its excellent degreasing and sanitizing properties. But what is the right ratio to use? The Ultimate Sodium Hypochlorite Mixing Ratio Guide For Soft Washing is a valuable resource.

Soft Washing Techniques

Getting the most out of your soft washing equipment involves learning the right techniques. For instance, cleaning rendered walls can be challenging, but with a helpful guide on How To Clean Rendered Walls Effectively, you'll be a master in no time.

  • Hello Peter,

    Thank you for reaching out. It’s great to hear that you’re considering incorporating soft washing into your render business. To effectively clean algae and other organic stains using soft wash methods, you’ll need a few key pieces of equipment:

    Soft Wash System: This is the core of your setup. A professional-grade soft wash system will allow you to apply the cleaning solution at low pressure, ensuring that surfaces are not damaged. Look for systems that include a pump, hose, and wand designed specifically for soft washing.

    Sodium Hypochlorite: This is the primary cleaning agent used in soft washing to effectively remove algae, mold, mildew, and other organic stains. Ensure you have a reliable supplier for this chemical.

    Surfactants: A surfactant like Clever Wash helps the cleaning solution adhere to surfaces and penetrate deeper into the substrate. This enhances the effectiveness of your cleaning process.

    Clever Injector: This is a helpful tool for applying your soft wash mix. It allows for easy and precise application of your cleaning solution.

    Safety Gear: Personal protective equipment (PPE) is crucial. This includes gloves, goggles, and protective clothing to keep you safe from chemical exposure.

    Water Supply: Ensure you have access to a consistent water supply, as you’ll need it to mix your solutions and rinse surfaces.

    Biocides: Products like Biocide Soft Wash Pro 50 can be used as a post-treatment to help prevent future algae growth.

    Application Tools: Depending on the surfaces you’ll be cleaning, you might also need brushes, extension poles, and other tools to help apply and agitate the cleaning solution as needed.

    Here’s a list of recommended products available from SoftWash UK:

    Soft Wash System
    Sodium Hypochlorite
    Clever Wash Surfactant
    Clever Injector
    Biocide Soft Wash Pro 50
    With these tools and chemicals, you’ll be well-equipped to offer effective and efficient soft washing services. If you need further guidance or have any other questions, feel free to reach out.

    Best regards,
    Mark Cave

Soft Wash Calculator App

Now you can say I've got an app for that!


Available NOW Click Here To Download

Softwashing calculator is an indispensable tool for juggling complicated chemical mixes. It helps reduce wastage and keeps operating costs down by giving accurate proportions

If you are having difficulty getting your head around the maths, trying to work out what percentage of softwash you need, how much chemical, surfactant and water to add, then this is the App for you.



The Soft Wash Calculator App allows you to work out your soft wash recipe by telling you exactly how much chemical, how much water and how much surfactant to add to get the desired soft wash recipe.
It doesn't stop there!.
- It can also remix your leftover softwash to a new stronger or weaker recipe.
- all controls in one place for see at a glance operation
- ease of input via pre-loaded dials. no more calculator style typing
- instantly responds to changes of complex combinations
- works in both Litres and US Gallons
- tested for Protan and Deutan colourblind users
- links to SoftwashingUK website

Take this scenario
You started with a 1% soft wash recipe of 50 gal (or litres)  for a deck clean and you’re left with 13 gallons.

You get a call from a prospective customer to clean their roof. Past experience tells you a 4% soft wash recipe is needed, but what about your leftover mix at 1%?.

Do you waste time and effort driving back to base to transfer into a standby tank?
You could consider the 13 gal as just water, top up the tank and start again.  
But that’s throwing away the value of the mix and raising your overhead.

Soft Wash Calculator App to the rescue.

You get to the new job and it requires 100 gal / litres.
Switch into remix mode , confirming the 13 gal already in the tank
Move the dials to your new recipe and the app immediately updates the different amounts to add in front of your eyes including the correct amount of extra surfactant.

You now have a 100 gal / litres tank of 4% soft wash recipe ready for your roof clean job!

Not forgetting you’ve saved money too, all without stress and uncertainty . Don’t underestimate what confident calmness has on your customer putting out referrals.

The same applies if you have a 4% recipe left in your tank and you need to dilute it down to 2%. Again the app will tell you how.

Softwashing calculator will also work for any chemical recipe. For instance you can use it for Sodium Hypochlorite, Bleach, Biocide , TFR traffic film remover and degreaser. Even the mathematically-challenged rocket scientist can top up their booster tanks to new fuel mixes after launch delays caused by changing weather conditions.

Using this app you will know exactly what chemical strength to put on any surface giving you the confidence and the knowledge of a professional soft washer and you’ll save money as well.

So if you have little knowledge of how to mix a soft wash recipe then this app is for you.
If you have little knowledge of how to remix a soft wash recipe then this app is for you.
If you want to save money when mixing a soft wash recipe then this app is for you.

This app is also backward compatible to devices running iOS7. We've done this so you can re-purpose an old iPhone 4 or iPod Touch 5  for what could be hazardous work environments. Just toss one in your cleaning van's toolkit.

Once you learn the methods and procedures of how to apply the soft wash to the different surfaces that need cleaning you’ll be unstoppable!

The app also has  a guide to what percentage for what surface. And if you are the lucky owner of a Clever Injector it will remind you the correct setting for the job.
However you should always consider and risk assess what soft wash recipe you need to clean the surface.

** A major iOS code-base change may require a re-purchase. The appiverse at the time will confirm our promise that we won't do so unless the necessity is apparent.
