Any one use Hydramasters Clearwater rinse? looking at their site it says the PH in dilution is 2.7 is this a little too acidic. Would chemspecs Highheat be a safer choice for an acidic side rinse? Or should i stick with Prochems F&F rinse

[mark_roberts]

Wouldnt have thought so as youll never get the carpet to PH2.7.

If you clean at PH9 and rinse with this at PH2.7 wouldnt it leave the carpet around 7 neutral.

Never claimed to be a chemical expert but Doug Holloway seems to be the resident expert on here so maybe he can explain better.

Yes true but i have never come across an acidic rinse with such a low ph

[Glynn]

Thats the best acid rinse on the market !.

Just putting a tub of Hydramaster Blitz in my van for a job tonight (might need it).
This has a PH at use dilution of 12.0 - 12.5
tub also adds - to neutralise alkalinity, rinse or pre spray with Hydramaster Rinse Out or ClearWater Rinse(PH2.7).
So using a high and a low at these levels will leave around neutral.
Prochem Fibre & Fabric Rinse is PH4

Hi Guysimes more basic

Joe has made a good point as most Prochem products are pH 9 - 10, then pH 4 will neutralise.

However Chemspec at pH 12 would need a much more acidic product to neutralise , everything else being the same, so 2.7 makes sense.

Remember the pH scale is logarithmic so pH 12 is 100 times more alkaline than 10.

To complicate matters further, an issue often of greater relevance than the "on the label pH"  is the buffering. For example, it's possible to have a pH10 self neutralising product that meets Woolsafe requirements (Ultimate Master used to be like this) and then you could have a pH7 buffered solution that fails the same test.  Ph on it's own is only part of the equation.

Safe and happy cleaning

As understand it the Alltec product still would meet Woolsafe, but Alltec choose not to spend the £3000.

Hi Doug

I've heard too that Alltec made a commercial decision not to remain with the Woolsafe scheme, and that the product had not been reformulated.

The opt out decision was made about 8 years ago and I think the change was physical rather than chemical but I could be wrong. I'm sure Steve keeps an eye on here, so you will probably get an answer.

I used to love HM Clear Water rinse, excellent product, didn't use it all the time, mostly on urine jobs.

Seems a lot give creedance to this clearwater revival  :

I can't add much more except to say IMO it depends what you use it with. Like Joe I carry Hydramaster's Blitz for those jobs which are "challenging" it folloes then that you are likely to need a more acidic rinse to get back to neutral. With microsplitters being so good I find I use it less and less but it's there if needed. I just happen to like the crisp smell it has, makes a change to the cherry/orange/citrus smell.
