Understanding the Use of DDAC Biocides in Moss Control: Legal Guidelines and Practical Application

Understanding the Use of DDAC Biocides in Moss Control: Legal Guidelines and Practical Application

DDAC Biocides Soft Wash Pro 50

As an expert in the softwashing industry, it's crucial to navigate the complex regulations surrounding the use of chemical products for cleaning external surfaces such as roofs, patios, and driveways. One common query that arises is the legality and efficacy of using DDAC (Didecyldimethylammonium chloride) biocides for moss control. This blog post aims to demystify the regulatory landscape, outline the practical uses of DDAC biocides, specifically focusing on a product like Soft Wash Pro 50, and offer clarity on their effectiveness and legal status in treating moss infestations.

What are DDAC Biocides?

DDAC biocides belong to a class of chemical agents known as quaternary ammonium compounds, which are widely used for their antimicrobial and algicidal properties. These compounds are effective in eliminating a broad range of organisms, including bacteria, algae, fungi, and lichens, making them a popular choice in the softwashing industry.

Legal Restrictions and Labeling

The legal framework governing the use of DDAC biocides is stringent. Under EU and UK regulations, specifically the Biocidal Products Regulation (BPR), biocides are required to undergo a rigorous approval process that determines their safety, efficacy, and environmental impact. For a product to be legally used for controlling a specific organism, it must be explicitly authorized for that purpose.

Herbicides vs. Biocides

The term "herbicide" is designated for products intended to kill or inhibit plants, including moss, which is classified botanically as a plant. DDAC biocides, while capable of affecting moss, are not registered as herbicides. This distinction is critical because it means these products cannot be marketed or labeled explicitly for moss control without the appropriate herbicidal authorization.

Practical Implications for Softwashing

While DDAC biocides are not labeled as moss killers, they are still effective in cleaning surfaces where moss is present alongside algae and lichens. The application of DDAC biocides for algae and lichen removal will inadvertently impact moss due to their broad-spectrum antimicrobial action. This incidental effect can lead to the death of moss, which, although not the advertised intent of the product, is a beneficial side effect for softwashing professionals.

Application Guidelines

To comply with legal standards and achieve effective results, follow these guidelines when using DDAC biocides like Soft Wash Pro 50:

  1. Surface Assessment: Before application, assess the surface for the type of contaminants present. If moss is among these, ensure that the primary targets listed on the biocide’s label (e.g., algae and lichens) are also present.

  2. Proper Dilution and Application: Mix the Soft Wash Pro 50 according to the manufacturer's instructions found on the SoftWash UK website. Apply the solution using low-pressure equipment to avoid damage to the surface. The application should be done during dry weather to allow the biocide to act effectively without being washed away prematurely.

  3. Safety Measures: Always wear protective gear, including gloves, goggles, and suitable clothing. Ensure that the area is well-ventilated and that pets and people are kept away during application.

  4. Environmental Considerations: Be mindful of the potential for runoff into waterways. Soft Wash Pro 50 is toxic to aquatic life; therefore, measures should be taken to minimize environmental impact, such as avoiding application near drains and water bodies.

Communicating with Customers

When discussing biocide use with clients, clarity and honesty are paramount. Explain that the Soft Wash Pro 50 is intended for the control of algae and lichens, and any effect on moss is incidental and not guaranteed. This approach ensures compliance with the law while setting realistic expectations for the client.

Case Studies and Testimonials

Including real-life examples and customer testimonials can enhance understanding and credibility. Share case studies where Soft Wash Pro 50 was used, highlighting the processes involved and the outcomes, particularly how moss was affected during treatments intended for algae and lichens.

Conclusion

Soft Wash Pro 50 offers a valuable solution for cleaning surfaces plagued by various organic growths, including moss. However, it is essential to understand and respect the legal boundaries set by regulatory authorities to avoid potential penalties and ensure safe, effective use. By adhering to approved applications and maintaining transparent communication with customers, softwashing professionals can leverage the benefits of Soft Wash Pro 50 to deliver excellent results safely and legally.

This nuanced understanding not only helps in complying with regulations but also ensures that you can provide your services effectively, keeping client satisfaction high and environmental impact low. The ability to navigate these legal waters is a testament to professional integrity and commitment to quality in the softwashing industry.

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.
