✨ Vanish Black Spots Effortlessly - Effective Solutions for Black Spot Removal!

A patio with lichen and black spots on it

👋 Today we're diving into two roaring topics recommended for all cleaning enthusiasts or folks battling stains on their exteriors: Black spots and lichen. Yes, that stubborn duo that clings onto surfaces and creates an unsightly mess. 😞 But worry not, at SoftWash UK Ltd we have got the breakthrough💡

Pro Tip: Removing Black Spots

Removing Black Spots


For a soft wash mixture to tackle black spots and lichen on a patio, creating a 10-liter batch with the specifics you mentioned can be done with the following recipe:


  • Sodium Hypochlorite
  • Clever Wash Surfactant
  • Water


  1. Sodium Hypochlorite: Since the ratio of sodium hypochlorite to water is 1:3, you will use 2.5 liters of sodium hypochlorite.
  2. Water: Add 7.5 liters of water to the sodium hypochlorite to make up the rest of the solution.
  3. Clever Wash Surfactant: Mix in 50 ml of Clever Wash surfactant to the solution.


  1. Mixing: Carefully measure and mix the sodium hypochlorite with the water in a large container. Once mixed, add the Clever Wash surfactant and stir the solution gently to ensure it is well combined.
  2. Application: Apply the mixture to the affected patio area using a sprayer. Ensure even coverage across all areas with black spots and lichen.
  3. Waiting Period: Allow the solution to sit on the surface for 15 to 20 minutes.
  4. Rinsing: After the waiting period, thoroughly rinse off the area with a pressure washer. This step is crucial to remove the dead lichen and loosened black spots.
  5. Repetition: If black spots persist, repeat the application process. For severely stubborn spots that have faded but not completely disappeared, a repeat application might be necessary. These spots will typically detach and erode away over time with natural weathering and additional treatments if needed.

Safety Tips:

  • Always wear protective gear, including gloves and goggles, when handling chemicals.
  • Ensure the area is well-ventilated during application.
  • Protect nearby plants and grass with a tarp or by watering them before and after application to dilute any overspray.

This simple yet effective recipe will help you manage and remove unsightly black spots and lichen, restoring the look of your patio.

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.
