Benz Bio Cleanze, DDAC based softwash biocide


Some customers have wondered why we add IPA (Isopropyl Alcohol) to Benz Bio Cleanze. So lets clear this up and clarify the situation once and for all ...

Why we use IPA in Benz Bio Cleanze

Isopropyl alcohol, as used in Bio Cleanze and Perma Cleanze, is known in the UK and Ireland as pharmaceutical “surgical spirit” and is used by doctors and nurses as a topical antiseptic for cleaning wounds to prevent infection.

Including 10-20% IPA (Isopropyl Alcohol) gives Bio Cleanze several advantages over a basic biocide:

  • It enables a full 50% of active ingredient (DDAC) to be added. Products made without IPA are limited to a maximum of 40% DDAC.
  • It improves the temperature stability of Bio Cleanze in cold weather, preventing the thickening associated with non-IPA products.
  • During manufacture IPA helps maintain the solubility and stability of DDAC.

Does IPA damage the silicone in some wall renders?

Not at all. At recommended dilution rates, the very small quantity of IPA in Bio Cleanze and Perma Cleanze as applied to a customer's property has zero effect on the silicone in, for example, wall renders and tarmac.

Quick tip: Even pure undiluted IPA has no lasting effect on silicone.

Fun fact: In the US, Isopropyl Alcohol is called “rubbing alcohol”. Why? Because when it was first introduced back in the 1920s it was used as a massage lotion.

Then prohibition came along and it was named rubbing alcohol to differentiate it from drinking alcohol, which was illegal. Because IPA is undrinkable it was allowed to be legally sold. And the name has stuck ever since. 

We sincerely wish you great success in your soft washing business.

Are pencil jets or fan jets best for soft washing brushes?

July 21, 2021

We use pencil jets in our brushes because we've found they don't clog or break as much as fan jets.

In the case of the Gardiner 45cm brush we use four of them. We turn the pump down so the flow rate is acceptable and does not produce much run-off.

Flow control at the pole is still critical however. Click the link on this page to learn about the solution we've found to be so successful ...
