  this is after cleaning its a mate's living room , tar oil /grease , he used to be a road worker. Is there anything that can remove it pre spray wise?  Tried oil remover as a spottet and it lifts it slightly , but a large area in  front of sofa and chair

It might be best to try a gel to remove the oil. Heavy use of liquid solvents will most likely result in delamination of the carpet.

Try this from Restormate - http://www.restormate.co.uk/epages/15094.sf/en_GB/?ObjectPath=/Shops/15094/Products/E840 

You would want to agitate it into the stains and leave it to work as per the label and rinse with hot solution.

I have some oil remover gel from John but it didnt work, i spoke to him on fb and he has something to try. Will get it next time I go as no rush for re clean

put white spirit in a spray bottle ,   spray  it on ...  extract straight away with warm water and a bit of detergent in your extractor  ( hopefully u have an extractor )   ...  repeat til gone

Will that mot burn the carpet? Yes I have airflex pro

[john martin]

No , it will do no damage , just extract after .

Craftex Multisolv prespray, agitated in with 15 mins dwell time, extracted with something like F90 should sort it.
