Hi, just wondered if anyone has used virisol on rendering and how did you get on? im not looking to get into soft washing but have been asked to do a 1 off for a relative, so  dont  particularly want to be buying special chemicals and equipment as im not charging them. Planning to use a gardiners backpack, soak the wall and scrub with an old window cleaning brush and rinse. Its not heavily soiled, just had a bit of green starting to show.

Virosol isn’t really suited to use on walls , but good on cladding, UPVC, and plastic coated commercial buildings .

[SB Cleaning]

Virosol wont do a lot..

Better off buying a tub of hypo and fill backpack 4 to 1 ratio  water to hypo with a squeeze of fairy scrub and rinse down.

Just make sure you run water through backpack at the end as you might damage pump otherwise.

Stick about 2 litres hypo  into your back pack top up with water - cover the wall - wait 20 mins job done - rinse backpack with plenty of clean water - Hypo will cost you around £15 for 20 litres

Jonny you can mix fairy with SH, it is stable, despite what someone says on ‘quora’ It will not create chlorine gas.

It’s all good.

How do I know? My dad worked with SH all his life as a technical engineer of 9 leisure Centers. It was his job, amongst many others, to look after the pool chemicals. Hence his knowledge of SH.

Just don’t mix it with any acids. That’s the big danger! Fairy is stable, it’s fine 👍🏼

You shouldn’t mix any washing up liquid with hypo as it produces hylothorms and chloroform’s  spelling is probably wrong but they are cancer causing  agents , it’s also illegal to mix anything with hypo that’s not designed to be added to it  , this is where the internet is a bad thing with false information, if you want to softwashing go on a proper course and learn from the professional s in the industry

There is a lot of conflicting advice, if you are referring to a course that purple rhino runs etc, then they will obviously say this to get you to buy there products.

I’ve spoken to clover chemicals and they told me that it would not cause any harmful effects, though they don’t recommend it.

A few dabs of fairy in a softwash mix isn’t going to cause any harmful odours. It’s stable.

In the end though, why bother using a surfactant, in my experience, it doesn’t actually make any difference, I don’t find it needs to ‘stick’ to the cladding/render, I find SH and water works just fine.

If worried, laundry detergent is the best. It’s designed to be used with bleach.

Lye and sodium hydroxide should be avoided, but you ain’t gonna find that in fairy. Fairy is some perfume, and surfactants. That’s about it.

You could argue that the tiny amount of alcohol in fairy would create a chloroform, but that’s really scratching the bottom of the barrel. And I mean really scratching.

Best thing is to use it with nothing but water. It works great without any surfactant.

I don’t think that’s wise advice mate. I’ve heard of others mistakenly making a mustard gas with hypo and washing up liquid.

That “quora” quote or whoever it was was just the first google. Take a look at some Research.

Best to play it safe with chemicals, and like you say, laundry detergent works better. I’ve used that myself.

I'm with Smudger
Put 2 litres in your backpack and top up with water.
Don't bother adding anything else for the minute.
Gently apply it using your brush to spread the hypo evenly over the wall.
Keep the pressure low and don't spray it everywhere.
Give it 20 minutes and gently rinse off.
A few points to note:
If it goes on your clothes, they are ruined.
If it goes on your skin (just wipe it off with a wet cloth).
Protect your eyes.
Try and buy 10 litres (rather than 20) cheaper and easier to mix.
Be careful when mixing (this is when you will spill it).
Be careful when disconnecting your pole hose from your backpack (the slight pressure left in your hose can cause it to splash onto your face).
If there are any plants below, just hose them with water before you start and again when you have finished.
Sorry to be a bit H&S on this, but if you haven't used it before, please be careful.

Robbo - easy isn't it!!!!


im not getting involved with all the use this don't use that - each of the soft washing promoters all slag each other of on the training days and they all want you to spend 1,000's on a machine when a £60 backpack does the perfect job

I don’t understand how that’s possible mate, unless these people are using a dish soap with ammonia in it.

In which case that is extremely dangerous.

SH is not to be messed with, but a bit of fairy thrown in with the water and SH won’t create mustard gas. You really need acid to cause problems.

Laundry detergent is the best thing to use, but some fairy Liquid isn’t going to be a problem.

Or just use water and SH on there own, that’s what I do.

Your are right, Chemicals aren’t to be messed with, but the scaremainering from these softwash companies isn’t helpful either, it reminds me of solar Steve and his scaremainering over solar panels!

Don't get me started on the price of a good watering can!

One of my customers is a top chemist with glaxo Kline  Smith and he told me exactly the same don’t mix washing up liquid with hypo , he took about half an hour explaining why it’s so dangerous, it’s also illegal to mix anything with hypo that’s not specifically designed and says on label that it can be added to bleach . I used to do so in ignorance , but not anymore , I di use surfactants on some wall jobs but I agree it doesn’t make a huge difference.
