This bio powder looks good.
But the key for me is not having to scrub, I hate scrubbing away. That’s where softwashing is so good, spray on, dwell, rinse off. Job done.
If that can be achieved with bio powder then I’d certainly use it, but if it means scrubbing. NAH
Softwashing doesn’t do away with scrubbing on some if not most jobs it is still needed all you are doing is making the dirt look translucent it is still there we have been softwashing for around 10 years and tried several ways of doing it the results are always better with a light scrub as well
Scrubbing is sometimes necessary, but we rarely need to.
I think what did it for us was:
A. buying a purpose built softwash machine from Ben and Rutland pumps.
B. Using our 21lpm pressure washer with a sniper nozzle (also from Rutland pumps) which is an absolute revelation for rinsing, it absolutely destroys all the dirt because the flow rate is so powerful.
I would be interested in using bio powder, but if it means scrubbing like you would with any degreaser then it’s not as efficient as softwashing.
