Had a chat with Doug Holloway about a job i had on a white cotton 3 pc suite this morning i used Nemesis on it and was going to use plain water rinse, Doug suggested a small amount of acid rinse to lower the surface tension and make extracting easier, when he said it i thought what a good idea, one that had not occured to me.
Thought i would share it with you guys, although i suppose some of you already thought of it.
cheers Doug thanks for advice the results were very good, although i hate cotton for the reasons you mentioned soon as you wet it panic can set in as it goes very dark but put the blower on it and it dried beautiful

Hi Jim Ive never used Nemesis,would you recommend it and who supplies it?

[Steve. Taylor]

James you could see the effect of what doug has said by taking a glass of water then add a drop of oil
in the other glass add a table spoon of vinegar it won't mix with the oil.

Another example of lowering water tension is  Fluorochemicals (carpet protecter)

Listen to Doug you won't go wrong

[james roffey]

Steve i inderstand the principle, as soon as Doug said it i though    great idea it will penetrate the fibre better, Solutions UK suggest rinsing with plain water all the time but i would have thought if you add something to the rinse like F and f of some other safe chemical it would rinse the fibre/material better,Or am i missing something.

Wayne

Nemesis is supplied by John Kelly at Restoremate i think it is very much like M Power i could be wrong if i am then Nick will no doubt put me right.

The dilution rate is higher with Nemesis, both are good though.

But then you're leaving a chemical behind in the carpet.  Good or bad?  Who knows really, we just trust they're ok because the manufacturers tell us so!

Surfactants "make water wetter", whether they may be detergent/colloid/microsplitter (what is the proper scientific word for microsplitters anyone??!).  I've never heard of acid rinse being used for the same purpose so maybe I'm missing something.  I've always been ubder the impression that penetrating into the fibre better is the real focus during dwell time of a pre-spray.

Stuff like m-power and microsplitters are very free-rinsing compared to detergent products, so you don't need to use an acid rinse in the same way as with something like powerburst for example.

Steve are you sure fluorochemicals lower water tension?  Water beads up on a teflon-coated frying pan... I'd have though that is the opposite

[Simon@arenaclean]

If you are concerned with residue using DFC 105 or pure clean in dilution would do the same 30ml in 20 litres, wont do any harm.

Hi Jim yes you are right the reason i used the example of fulorochemicals in the process of reducing the surface of water tension they are opposites your frying pan example is good. We all know water mixes with water very well take another example water on the bonnet of a car when it rains forms like a sheet but when polish/waxes/silcone based products are used the water as you mentioned beads as droplets lowering the water tension you then have a interface tension 2 opposite liquids.

If as in james situation you are rinsing with just water by adding the fib fab or acidic solutions you are lowering the surface tension of the water making it easier to rinse, but as he was using a very free rinsing product like nemesis there was  no real  need as we know. but as physics goes doug is right.

Right now i am boring myself let alone the other forum users thats all the sensible post your getting from me this month HOW MUCH TO CLEAN ME TRAINERS

Jim is right!

Lower the pH with acid prevents cellulose browning for cotton is the purpose rather than making the water wetter.

Hi Guys

Acid rinse will lower the surface tension.

Prochems Fabric and Fibre rinse contains both Citric and Glycolic acids, both of which will lower surface tension.

Cheers
