Alex,
I have just got home fron cleaning a 14yr old, cream background polyester brocade suite that was so absolutely filthy that most of the green and pink overlay stripes were no longer visible. Stains included several types of ink, crayons, assorted beverages and many I would rather not put a name to.
Pre-spray was Solution Nr 4 (the micro-splitter that Nick was refering to), rinsed with plain water.
The only other spotter used was Solvex and the result was so astounding that I thought that the husband was going to kiss me as well as his wife
(Incidentally the whole family was sitting on the suite watching the Simpsons before I drove away)
To any one who has not tried micro-splitter technology, I highly commend it - but allow yourself a learning period to experiment with dilution, dwell time, agitation levels etc. before reaching your final conclusion.
John.
