Fancy trying Powerburst but website says dont use on wool or wool mix carpets. That true? And if so. Why?

If the carpets are trashed, I will use pb on wool. It is important that you acid rinse though....
-
No, it is not true. We've been using PB on wool carpets for years. Just got the data sheet......

and it says to acid rinse on wool and wool mix carpets.

You can use it but as has been said it must be acid rinsed to return it to a safe ph for wool, if you are cleaning carpets you should at the very least do a NCCA course as this is basic stuff.

Done an NCCA course and it was pants.

couldn't agree with you more cleanability

Cheers Jamie. Vary rarely anyone agrees with me on here.

Hi Guys
In theory Powerburst, being highly alkaline will start to attack wool fibres and willm only stop when removed or neutralised with acid.
In practice the damage will be minimal if the dwell time is relatively short but remember if PB is pH 11, you will need a great deal of acid rinse at 5.5 to neutralise it, even miore if highly buffered.
Thorough flushing with water will have much the same effect.
I believe acid rinse although good in theory is largely irrrelevant in practice, especially if using a TM.

Doug has pretty much taken the words out of my mouth... thorough flushing is the important bit, but they don't tell you that on the label of products, or at a basic CC course.
For the last couple of years, since changing my extraction machinery (carefully avoiding the same old debate again here!) I've found that I can pull 2 or 3 times the amount of water through a carpet and leave it just as dry if not drier. If you remove the product, it can't cause a problem! The acid rinse is just a bit of an insurance policy in my opinion, and should be treated as such.
I regularly use powerburst, ultrapac, HD microsplitter etc on wool... gotta use the right product for the job in hand! Don't forget as well that a lot of soils are acidic in nature, therefore partly cancelling out the alkalinity of the pre-spray

On a rental property with wool carpets 80/20 i have used powerburst and rinsed with chemspec formula 90. Carpets cleaned 3 times over 2 years. I cant see any deterioration in the carpet at all. When i first cleaned the carpets i ph tested after rinsing with formula 90 and the test was not high alkaline, slightly over neutral. I rinsed with truck-mount, in my opinion the truck mount is rinsing everything out, including the formula 90. I find the formula 90, despite getting rinsed out does lift more out the carpet than high heat. This is on my own property so i can experiment.

Well coming from you Doug maybe people will believe it. The acid rinse idea I'm convinced comes from chemical manufacturers to make more money out of carpet cleaners.
The next time you clean a carpet that's really dirty wet it and test the ph, you might be suprised, but not as much as when you tested it after you have presprayed and agitated.
On the other hand using PB on a very lightly soiled carpet with certain natural fibres will bvgger it visibly and the acid rinse conecept doesn't wash. It's like sticking your hand in boiling water and then in ice to counteract it, it don't work that way.
Always go easy until you have the experience to know what's what.
-
surely if you stick your hand in boiling water you will reach natural body temperature a lot quicker sticking your hand in ice afterwards, you will also cancel out the heat before it does even more damage and from that conclusion i would say you should always icid rinse. ;D
-
I had a day where I did 4 jobs, all with powerburst on wool. I forgot to turn on the chemical meter with the acid rinse. Only noticed at the very end so I went in to check the PH and it was fine, pretty much neutral.
I think you have to learn about the fundamentals about PH balance because not everyone gets to use truckmounts and I would think quite a fair bit of residue would be left over had I used an entry level extraction machine

Could be the basis of a TACCA initiation ceremony.

Powerburst like nearly all presprays will dry neutral, if extracted/flushed correctly with plain water.
I have used powerburst for about 2 years for about 90% of my carpet cleaning jobs ( wool and syn) and have nver used an acid rince. I have not used an acid rince on normal extraction for about 5 years now with absolutley no problems to any carpets.
There are times on a minger when I need boost a prespray to a major level and an acidic rince is then necc to neutralise quickly .
-
our water in the west of scotland is naturally acidic, so i have never used an acid rinse.
-
It does not say on the product that you should not use on wool, it says you should acid rinse if using on wool, i use it regularly on synthetics and wool, i think Dougs theory may be true if using a truckmount but i would not rinse with just water with my machine just in case
-
I used to think PB was fine on wool until I turned a cream carpet brown. Yes I used acid rinse. But clearly not enough. Managed to rectify it but my heart was very much in my mouth for a day or two. I wouldn't risk it again.
