I hope that you are all staying safe and looking after your family during this difficult time.
One of the questions that we get asked so much here at SoftWash UK is how do I make a Softwashing recipe.
Well I thought I would do some of the maths for you and show you the basics so you get a greater understanding of how to work out your recipes.
So check out the examples below and hopefully this will make you more confident when it comes to mixing your recipes.
Soft Washing With 15% Sodium Hypochlorite
Here is an example of a batch mix 100L recipe @ 2.14%
1 part Sodium Hypochlorite to 6 parts water = a total of 7 parts
Sodium Hypochlorite @ 15% divided by 7 parts gives you 2.14% softwash recipe.
100L / 7 = 14
100L - 14 = 86
So you would need 86L of water and 14L of Sodium Hypochlorite which is 100L in total at a softwash recipe strength of 2.14%
Here is an example of a batch mix 125L recipe @ 2.5%
1 part Sodium Hypochlorite to 5 parts water = a total of 6 parts
Sodium Hypochlorite @ 15% divided by 6 parts gives you 2.5% softwash recipe.
125L / 6 = 20
125L - 20 = 105
So you would need 105L of water and 20L of Sodium Hypochlorite which is 125L in total at a softwash recipe strength of 2.5%
So find the required % recipe you want to work with, then take that figure away from the litres you want to make.
I want to make 100L of 3% mix
100L - 20L = 80L
80L of water + 20L of Sodium Hypochlorite = 100L of 3% softwash recipe.
If maths is not your thing then dont worry we have an app that you can download on your apple device. You can get it HERE
Now you can say I've got an app for that!

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.

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.
