Acid Rinse Dwell - spotter stain
« on: October 25, 2014, 06:02:20 pm »
Hey all

Have been given a stain on a cotton sofa (similar to ikea klippan cover) that appears to be from a spotter a previous cleaner used very recently

Its very alkaline like stain

Have given it an acidic rinse with Prochem Fibre & Fabric Acid Rinse at the max of 50ml to litre - but only left it to dwell for a couple of minutes

Was wondering how long can you leave this stuff to dwell

The cotton is a very tight weave - so not sure how penetrating my dwell is

Also if this dont work anyone got any ideas

any help would be great - have attached a pic

Are you expecting  the acid rinse to reverse the damage done by the previous spotter?

Acid rinse is only mildly acidic if you want to neutralise an alkaline then I would use browning prescription or Prochem coffee stain remover, but this looks like fading which is damage so cannot be reversed.

It might be whitish residue from the spotter which would just rinse out but fading would be my guess

It looks like to me the previous cleaner has used a reducer/oxidiser in an attempt to remove the small dark spot and lightened/knackard the surrounding area i.e. the white patch.

Or maybe its been rubbed to death.

Have you rinsed it? Sometimes if you don't fully rinse out a solvent on this type of fabric your left with a whitish patch. But this is usually very obvious when the fabric is still wet.

Have you been called in to rectify this one stain? These are the types of job that you turn down brah.

Was trying to do this mildest way poss and did anther acid rinse. It has improved again slightly. So I'm still thinking residue

Think it needs a bit more punch with a longer dwell - not sure how long you can leave prochem spray bottle mix acid rinse on for

Alternatives would be browning prescription or coffee remover

Which would be best to finish it off

It looks to me like the customer has used Vanish on it and if so it is a done deal.
Personally I wouldn't play with it, I'd give it a go as you have and leave it at that.
The risk is that through trying to fix something you didn't cause you could make it worse and end up with the blame in your lap.

Half the skill in stain removal is knowing when to leave it alone.

used the prochem coffee remover with a ph 2.5 and its seemed to take back just far enough

strange reaction i have never had before
