A customer asked about soft washing with Bio Cleanze biocide:
1) Is there a minimum temperature for soft washing with biocide?
2) Is there a maximum temperature for soft washing with biocide?
3) If so, what effect would it have if we used outside this temperature range?
There are many variables, including the long-term effects of "self-cleansing" through the actions of sun, wind and rain, which happens faster in warm weather, to take into account.
We recommend spraying above 7/8 degrees C and below 30 if at all possible. This temperature range gives the most consistent results.
20 degrees is the optimum application temperature and we have generic test data that was carried out at 20 degrees.
However, there's some scope for using Bio Cleanze outside of this range, depending on the weather and type of surface being treated.
Applying above 30 degrees can create boil-off issues. To offset this in conditions of extreme heat:
In general it's best not to use Bio Cleanze below 7/8 degrees. This is because below this temperature the product may not work consistently at the dilution rates we recommend on the product label and other material.
However, the good news is that applying Bio Cleanze at lower temperatures will not have a detrimental effect on the surface being treated. It will just take longer to show results.
Quick tips: We've successfully used Bio Cleanze at lower temperatures, down to as low as 4 degrees, by following these guidelines:
1. Plan your working day so that the product is applied at or just before the warmest part of the day. This can work particularly well on days that are cold but when there is direct sunlight.
2. Use warm water, max 45 degrees, to dilute Bio Cleanze before spraying.
3. Use a slightly stronger mix ratio than stated on the application guides, i.e. the mix ratio you would use in warmer weather.
We hope this information is helpful and sincerely wish you great success in your soft washing business,

It's a free resource for people wanting to learn about the soft washing industry, to expand an existing business, or build a new business.
Soft washing reduces, or even eliminates, the need to use high-pressure washing.
Instead, once the build up of algae, lichen, fungus and mould – the root causes of properties looking "dirty" – has been treated, the natural "self-cleansing" of sun, rain and wind removes the surface residue through time.
By educating the cleaning trade and public about soft washing we are helping develop an industry that offers sustainable treatments to clean and maintain exterior hard surfaces.
