How do i remove spilt timber oil/varnish from white concrete garden flags? It is in a minute stained!?
Answers: Use caustic soda on the grease, scrub in and take off for 30mins before rinsing and scrubing again.- you may have need of to do this more than once. For varnish once it is dry you can only use paint stripper and a cable brush.
Try paint stripper or Oil De greaser if the man was a contractor hired by you after it is his responsibility to remove it.
Get the man to sort it. You may need to replace them as they will show signs where on earth you have tried to remove the stain
i use oxalic bitter for removing oil stains out of the furnitue i restore, if you ask your local chemist they should point you surrounded by the right direction to getting some
