What chenical or detergent for snow foaming onto windows/fascia

[AlexH]

I have a Karcher pressure washer, extendable lance and about to buy a snow foamer.

What chemical should I buy to spray onto the windows, PVC, fascia etc in the below pics?

I already have some 11% hypochlorite for patio washing, would anyone advise diluting this down and spraying on the areas shown?

Why would you use 11% on a patio?

I planned to dilute it, perhaps 50/50 ratio

That’s still a bit strong for plastics , liable to turn them brown /yellow and cause clean streaks down the walls as well .

 

[AlexH]

I see, what strength would you suggest for windows/walls/plastics?

(or is it even a good idea, could use some kind of detergent instead (like this one)

2l hypo for every 10l water will be 2% if using 11% stock hypo
I would use that as a maximum on upvc
Preferably weaker than that

As @Dave B has said if doing walls then 4-1

Snow foaming hypo above you sounds like a accident waiting to happen. Avoid unless absolutely necessary. Even then, 1% strength is fine. I’ve never used ‘snow foam’ though. It looks great on videos, but is it actually needed?

I would use- Any kind of tfr, ubix, virasol. They’re fine for dirty windows, fascias gutters.

Gutter vac systems have brought out a non-caustic & caustic TFR. I’m going to try the caustic one on a absolutely filthy gutter & fascia clean job next month. Feel free to try that and let me know how you get one if you like ?

Hot wfp does the biz on most gutter jobs completely safe i only use tfr on really bad jobs using hypo would be my last resort for obvious reasons

That job looks like an average clean and absolutely no need to use any chemicals at all, wfp will do the job just fine and avoid any issues with runoff onto the render, no point make more of a job for yourself than needed.

Thanks for the advice. I'm not a pro so my equipment can't do hot water. I have a Karcher K7 pressure washer and telescopic pole (this telescopic pole).

You think better to just try that with cold water? there are things like spider eggs sacks around the windows that are pretty stuck on.

I can get Virosol from a supplier near me for very cheap (virosol) and I have the karcher snow foamer which goes on the telescopic lance.

To be fair it needs scrubbing with a brush not just spraying that’s the key to removing the things you have mentioned

You are cleaning windows and fascias not doing a carwash, the soffits are vented and you'll get water ingress into the soffits messing on with a pw

I'm assuming if your not a pro and the equipment you describe this is your own house and just doing it yourself. Forget about a pressure washer on windows and guttering you will quickly blow seals and cause all sorts of problems. If you are putting chemicals on do you also have a supply of pure water to clean the windows after? Tap water and chemical spray on the windows will need to be cleaned properly straight away.

My best advice would be spend the money your paying for equipment and chemicals which are completely wrong for the job in hand and pay a professional who could come and do it fully insured in no time atall for you!!!!!!

I had this discussion once with a neighbour of a customer who proudly showed me the water fed pole and system he had invested in to clean his own windows to save the cost of a window cleaner. His face was a picture when I told him his neighbour only paid about 12 quid or whatever every 6 weeks for me to do it for him. He could have probably paid me to do it for 10 years and been better off at the end of it and never lifted a finger himself ?
