Thats one point Smurf …it's hard to control drift.
He is a clue for point number two…effects on Organic and /or metallic surfaces.
See if you can figure it out yourself…maybe nudger can help you.

Can I play?

No 

I generally brush chloras on for that same reason be it hard surface areas on the ground or walls..
You do have to be careful as is also corrosive on some metals not to mention harmful to aquatic life, organic life, pets, kids etc too. Apart from that it's fine

Miserable git

Thanks for the info. Have ordered a x jet from the USA which should work on 2 storey buildings.. would like some further info on the extended lances I have seen on various videos..

Sorry for being thick, with the x jet it draws the diluted chemical from a container? So does it not further  dilute the chemical when using the lance with the x jet at the end??

Are the chemicals available on the market just a dearer form of hypo??

Trying to educate myself before I clean my neighbours render.

Following as I am looking to gain as much knowledge as possible before i tackle my own roof as a trial 👍 Interested to get any advice on a suitable wfp to use (pros and cons) and if anyone has any links to a soft wash in a box type of idea in the UK that would be very much appreciated 👍

X jet draws neat chemical and then mixes it with your water flow, you get a set of Venturi's ( I think that's the name of them ) which allow differing mix ratios

I've adapted some gardiners clx poles to take the X-jet which also has a shroud around it ( stops wind drift when applying to walls etc  ) and other pressure washing bits.

I'm sure our resident chemist Chris will be more than happy to list plenty of options - but hypo is pretty much the most effective chem for algae ( just be aware it has its drawbacks and dangers)

X-jets are as far removed from "soft washing' as you could possibly get. X-jets need around 3000psi to work (and a pressure washer). "UK' Soft washing is the application of  a chemical (to do the cleaning)  typically we  use around 10bar at 10lpm …reducing the risk of damaging to the surface (althoughh chemical damage may occur). "American" softwashing consists of spraying bleach at everything and anything .
Below is a specifically made pump aimed at the UK softwash market.

There we go, told you the expert would be along - thx for the info Chris, much appreciated.

Do you spray this on vertical surfaces ?

Darran

[chris scott]

No problem…glad I could help.

[Smudger]

So do you ?

Darran

[Smurf]

So do you ?

Darran

Smudger if you open the pdf that chris has posted you will find out. 

[chris scott]

So do you ?

Darran

Yep…(sometimes) we spray  on vertical surfaces.

[serj shergill]

Thanks, if you don't mind scott where can you buy those specially adapted pressure washers from?

[chris scott]

Rutland pumps.

[serj shergill]

Thanks once again for sharing your knowledge, have spoken to Ben and will be paying a visit soon..

[serj shergill]

forgot to ask, will I require any special licence from my local authority for the use of chems for soft washing?

[scott aird]

Precisely why I never fit chem pickups to our machines - I don't take them off the Dual machines but I don't fit them. I always reckoned the GP stainless Soap Shooters which pick up at the lance.

do you have a link for this? cheers
