Can someone tell me the best way to get the good results I have heard about on upholstery, this would be a big help.

A few months ago Dynafoam (john) gave me some good advice.

Excellent pre-spray (subject to pre-test) - especially good for body contact soiling.

Lightly pre-spray (hot) & agitate with tampico brush, then extract.

Alternatively may be removed by terry toweling. I have used this method on antique tapestry which was too frail to survive extraction cleaning even through muslin. this was followed by a spray on B109 Fibre & fabric Rinse + more towel blotting. Results were most impressive  on one particular piece - a hand embroydered settle completed in 1560 and as far as can be determined, not previously cleaned.

Definately a must-have!

As i say this is Johns


All the best

Just to make sur we are talking about b108 fabric restorer by prochem above .

[md_cleaning]

Yes Alex b108 thats the one, have you ever used the foam to clean, as this is what I saw at Prochem, but did the 4 in 1 course so not much detail, am going on the full day course soon, so want to know the best option for good results.

Dave,

The use of foam as a 'carrier' for a pre-treatment chemical is a way to limit the penetration depth, thereby reducing the risk of over-wetting.

There are several methods of generating the foam other than with specialised machines such as the Von Shraeder.

The easiest ways to use B108 it this manner is either:

a)  To apply the product via a trigger or pump-up sprayer fitted with a foaming tip.

or

b)  To mix B108 with a high-solids neutral shampoo such as Prochem B105  in a bucket. The foam is then created by whisking or better still by wetting and sqeezing a sponge. the resultant foam is then collected on a tampico or horse hair brush an appied to the upholstery.
When useing this method requires defoamer to be added to the waste tank of the HWE.

The latter method produces a  more durable foam.

I find the foam method with oxi brite really good on cotton prints.
B108 on its own for most other fabrics subject to testing, also i find on very weak  or worn fabrics use a net curtain over the damaged area to stop it from ripping

[Dynafoam]

Nick,

I would add a note of caution as to the use of Oxbrite, in that it is a bleaching agent and old, faded prints  may loose some colour and posibly some strenght. Also, since it has a fairly high pH, something  like Fibrebuff should be added to the mix.

Protecting weak fabrics with a net curtain dureing extraction does make sense, however a muslin nappy gives better protection and less impeadment to the extraction tool.

Protection netting....I use the black polyester mesh that is used for caravan fly screens... excellent ...and withstands chemical contamination too

Cheers

Derek,

Thanks, a great idea - the polyester mesh would be less absorbent than my muslin, and probably less obstructive to the 'blast effect' of the spray jet.

Hi John you wrote,

mix B108 with a high-solids neutral shampoo such as Prochem B105  in a bucket.

What dilution rates are you using

Regards,

Eric

[Dynafoam]

Eric,

Both products diluted at their standard strength, but with 'shared' water.  This produces a creamier foam but the pH is still 9.

John,

I may be missing the point a bit here - but why would anyone want to use a shampoo mixture in this day and age

By the way did you get my pm on the other unmentionable new board regarding the price of the Recoil.

Hi Nigel,

The only point in adding the shampoo is that it helps hold the pre-treatment at fabric surface. This way be desireable due to substrate problems - indeed I have only used this approach on very dirty antique upholstery, for example with 100 years of penetrated soil sitting in horse-hair.

If I remember correctly, Ron Tilley used to promote the use of this approach as a 'turkish' clean.

Thanks for the  PM, yes, the numbers are about what I expected. Have Emailed them a few minutes ago.

Regards,

John
