Anyone have a contact number for them I've left email s for them but no reply

[Smurf]

Nope I don't have their contact number.

However I've found Ben or Leo normally respond within a day or two via email as they don't just sit around all day long in an office like some.

I've emailed them and so as a mate off mine no reply to either of us

Can't understand a forum full off cleaners and only really had a reply from smurf makes me wonder if the black wash is really any good ,seams to me that no one else has used it

I pay £11 for 20lts of hypo which is almost the same and I get it from a farm shop 2 miles away from my home, why would I pay extra for perfume/maybe surfactant  and the inconvenience of getting it delivered?

I wouldn't allow it to touch anything I am not cleaning, so would be very careful were it runs off or over-sprays, plus it does not remove dirt, it bleaches, the  contaminant is still there you just cannot see it

I just love these sot wash threads : EG"the  contaminant is still there you just cannot see it" It`s a  bleach, its a gas and will evaporate very quickly after being  applied, you should only work with 2% to 4% strength which is regarded as safe. Then once you rinse it off which will then dilute even more.

'Bleaches' are an interesting subject considering bleach is a word use to discribe  a number of different chemicals, what we are referring to in this topic is oxidising bleaches which create oxygen within the chemical action, as opposed to reducing bleaches which reduce the oxygen, but both have the same effect which is altering the way light reflects so making it seem invisible, this is why spraying hypo on black spots makes them disappear even before you rinse

Quote from Internet..

. Natural stains (as well as dyes) produced by everything from mildew to grass come from chemical compounds called chromophores. Chromophores can absorb light at specific wavelengths and therefore cause colours. When chlorine reacts with water, it produces hydrochloric acid and atomic oxygen. The oxygen reacts easily with the chromophores to eliminate the portion of its structure that causes the colour

But bleaches are one of the safest chemicals we use

So everyone uses hypo mainly?

SH is cheap and readily available but still you need to know what you are doing to reduce the risks involved in using it.
What worries me is that many getting on the softwashing bandwagon don't have a clue what they are doing and there are still plenty of cowboys out there too.

This may be of interest to some as is applicable to whatever brand of sh based product or biocide you decide to use. https://www.youtube.com/watch?v=qTB5dlDr_4c
