Hi all,

We are doing more and more cleans using hypo as apposed to power washing, speed, effectiveness etc being the main reasons...

One thing I was looking into was alternative methods to scrubbing it in. Currently we spray on the hypo mix then manually scrub using decking brushes but this is very labour intensive and slow.

Has anyone used some sort of mechanical rotary scrubber type of thing if  so can you point me in the right direction.

Cheers

Matt

Hi Matt

We've used a rotary scrubber (victor sprite 400) tbh it doesn't seem to make any difference from just spraying it on and leaving.
Maybe if your using some of the acid cleaners it would be more effective

Where it does work well is with ot8 over oil patches.

It is very important to pre wet any surface first.  So you pre wet with plain water until the surface is saturated.. Then spray the hypo on if you must and allow to dwell then scrub with |Mono Rotary fitted with appropriate brush and then extract, rinse and extract again.  this means the Hypo stays on the surface where you want it to work and doesn't soak into the stone sub surface.

I sell loads of these Rotry Cleaners new or secondhand

Why how big is it?

[Mike Halliday]

Hypo is an oxidising bleach it does not remove anything it alter the amount of oxygen within the cells effecting how it reflects light, so rendering it invisible. The stain or whatEver you are trying to remove is still there.

It does have a killing effect on some organic matter which would allow easier removal but as we use it we want purely a cosmetic effect

Scrubbing/aggatation is about loosening & distributing the prespray into the soil ready for removal.

 why scrub hypo?  The porous stain is less than 0.001mm thick it will absorb the hypo to its full depth, it does'nt require 'scrubbing in'.  after using a watering can I use a brush to makes sure I give an even coat of hypo over the full surface and to stop the hypo sitting in dips and valleys.

[Rob@Blast off]

I get better results when an area has been scrubbed opposed to just leaving it?

[Mike Halliday]

Rob could it be that you are just spreading it about more?, I find most drives and patios are never completely flat, so the hypo runs off & sits in shallow dips so doesn't evenly work across the full drive.

I've dribbled it across paths as I walk from the tap to the drive and left clean spots (with no powerwashing or scrubbing)

[Rob@Blast off]

Do you not use a surfactant with it then?
I don't know what all the hype is with hypo there are better products out there depending on the job etc

[Smudger]

Such as rob?

I always spray, rather than pour out of a watering can and use a cherry or bubblegum smelling detergent this makes it stick rather than run off

Why would I need to use a Surfactant with hypo ?

For what I  use it for hypo is the best choice. It's economical and does a great job.  I'm not using it as a cleaner more a problem/stain remover

The bubbles hold it on the surface (where the problem is) ,they prevent run off and generally you will use less product. We also use wallpaper paste to "gel" the bleach for the same reasons.

[Mike Halliday]

I can see the use in that , it's was the use of term surfactants  which covers a multitude of  actions it's Also a wetting agent  which would do the opposite.

I have been thinking of trying some sort of thickening agent with the hypo (for all the walls I've been cleaning lately)

[wpclean]

I followed Blastaway advice, and use Amine oxide ( 5% ) added to hypo, which thickens it, and allows the hypo more time to work its magic.Think it costs about £50 for 25 lts  from Walker bros,

What do they call it on that site? I cant find it. I'm currently paying about half that price for only 5 litres

You will have ring up, and order the 25 lt as it is not usual size they sell.    I normally order day before, and pick up when get he Hypo.

Darran

Interested to know what product you use. Bubblegum smelling sounds good, its gotta be better than the bleach stench.

[Smudger]

Just a straightforward detergent, should get it from any cleaning suppliers

When searching I noticed the yanks seemed to put cherry in with the hypo, so I followed suit, it stops the hypo running off the surface, I just changed from cherry to bubblegum smell

You've set my mind at rest Mike. I spilt some on my trousers and what looked like a hole has appeared and i can see my leg. But if i rub it with my finger then it feels like my trousers. So the trouser is still there, but its like an invisible hole and the material is there but i just can't see it. I think thats how they're making all these skinny jeans for birds with what look like rips in them, they're pouring hypo over them.
