Clean It Up

Been into the darkest recesses of the unit this afternoon and I came across a black 20 litre drum.
Pulled the drum out and it is Cliniclor (hypo). I know I bought it ten years ago to clean out three IBC tanks but I cleaned them with a pressure washer and it just got left in the corner.
Completely forgot I had it.
Off came the lid, poured a little on the concrete floor (dirty but not wet), kept smelling bleach - I thought it would be good for nothing.
Put the hose on it to wash it out of the doorway and it has stripped the concrete clean.

Welcome to the club!

But I thought it went of after 4 weeks ;D
-
I used a year old tub yesterday and it was crap. Got a fresh one out and it did the trick!
Must be potent stuff that Rob! Was it sealed?
-
No - It had the seal broken. Was in a black drum though - that's not going to allow a breakdown by UV but I don't know how it is supplied in modern times?
Rob ;D
-
I always tell my supplier to give me my hyop in completely sealed drums without the pinhole breather hole in the lid. Only problem is i need to be carefull cause the drums expand a bit. :-\
-
kept out of the sunlight and it doesn't really go off, as long as it is 13-14% to start with, which is what most on here use. 10 years though Rob, really!!!
-
interesting topic, nice to know this for future reference, can't understand why suppliers don't stock them in black drums currently / anymore if this is the case for shelf life reasons, they could have loads on stock without fear of it going off. I know that it can come in the 205 litre blue drums which would have the same eefect and if you had a chemical pump could take what you need, when you need it. ;D

Unlike Rob, I don't keep mine for 10 years!!!
We get our's in either black or blue drums, all re-fills so always a fresh source, but in an unopened container kept out of sunlight no reason it shouldn't last 12 months, if you mixing it down then maybe make it a bit stronger to allow for some disintegration of the chem, so what was once 3:1 make it 2:1. Our turn around is quick enough around 200 lts per month so it don't sit around long.

Look forward to seeing on the Antiques Roadshow some day ;D ;D

The guy I buy hypo from said it will last a long time, as long as it is kept away from sunlight.

i was recently told when applying it is best applied mixed with cold water and not hot as heat destroys its strength, i was told this by a leading chemical supplier for the food industry what do you lads think.
-
I don't think anyone mixes it hot to be honest mate.
Normally use tap water

No advantage Trevor in using warm or hot water with hypo, with some powdered chemicals there is an advantage but NOT Sodium Hydroxide cold water only, it's to unstable.

i have often applied it to surfaces through my hot pressure washer after cleaning at a 5% mix through a venturer which gets rid of any slight stripeing obviously this is not something others have been doing
-
My opinion of a warm mix in cold temp differs. I don't know if it breaks it down but I had an intuition that it worked better in said cold temp than a cold mix does. Also read along the same lines on PI in US.
But then again most of you don't have work in Winter. (Tumbleweed) ;)
-
Hot water (liquid) is wetter than cold .....thats why it works better.

That was my thought on the subject to, but apparently the hot water breaks down the effective effects of hypo.
-
Hot water will cool in seconds when it touches a cold surface so unless it creates more activity/ strength within the solution I can't see how using hot makes any difference
The Oxygen bleaches used in cleaning are excelerated by adding strong alkalis, although I don't know how hypo will react to this (so don't recommend it)

As you say hypo will help get rid of stripe and lance marks, but no advantage with it being mix in hot water,
Mixing it in hot water in the winter, again no advantage as the hot water cools/dry's quicker then cold water when hitting the surface so evaporation is quicker, and you want the chemical working on the surface not drying out.
Adding oxygenated bleaches to hypo is ok, but it is just a short boost for the hypo, doesn't seem to clean any better or any worse IMO. Just be careful of what you are mixing & applying in.
