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
