Fibre fabric rinse will do the trick.
If you don't mind me asking how did you get into fire work?
Fire work is easy to get into if you have got a franchise which is on insurance panels. If you are a sole trader trying to get fire restoration work it is hard. You need to go around local loss adjusters although they are tied to who they can use they do have some flexability. The money can be very rewarding.RegardsJamie.
