Hi,i have a problem with my flavel oven not igniting,last night i accidently spilled some liquid on to the burner and now it wont ignite.i have thoughly cleaned and dried the area and it is sparking and you can smell the gas but just wont ignite.I tried using a lighter with some sucess but the flame was higher on the right so i am wondering if its safe to use.Any advice would be much appreciated,thank you.
