Wondering how to remove those unsightly black spots and lichen from your exterior surfaces?😕 Don't worry! You've come to the right place. In this article, we'll explore the most effective techniques for eliminating these stubborn stains and keeping your exteriors looking their best! ✌️

What Causes Black Spots and Lichen?

Black spots and lichen on exterior surfaces are typically caused by a combination of algae, mold, and fungi. These organisms can create unappealing stains that are notoriously difficult to remove without the right tools and knowledge. But the good news is, with the right soft washing technique, you can clear up these stains and leave your surfaces looking like new.💫

Why Soft Washing?

Soft washing is an efficient and environmentally friendly 🌍 cleaning method that can effectively remove black spots, lichen, algae, and other stains from exterior surfaces. Unlike power washing, soft washing doesn’t involve high-pressure water jets, but relies on specially-formulated soft wash chemicals, which minimise the risk of damaging your surfaces.✅

Performing a Soft Wash

Carrying out a soft wash requires the right soft washing equipment, chemicals, and know-how. Here's a quick guide on how to remove black spots and lichen:

1. Preparation:Safety first! Make sure your skin and eyes are protected. Use a soft bristled brush to remove any loose debris from the surface. 🧹 2. Mixing the chemicals: Follow the Sodium Hypochlorite Mixing Guide to prepare your cleaning solution. 3. Applying the soft wash: Using your soft washing equipment, apply the solution to the surface. 4. Rinsing: Rinse the surface thoroughly with clean water. Remember, if you're unsure about the process, it may be best to engage a trained professional or attend a soft wash training course. 🎓

Keeping Black Spots and Lichen at Bay

Did your exterior surfaces get the much-needed ‘facelift’?😃 Remember, cleaning is only half the battle; the other half involves maintaining your newly cleaned surfaces. Use a Green Growth Inhibitor to suppress the growth of these organisms. 👍

Wrap Up

So there you have it, a comprehensive guide to getting rid of those pesky black spots and lichen.💪By choosing soft washing, you’re not just keeping your exteriors clean, but you’re also doing your bit for the environment. What could be better than that🌱?

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.
