The liquid in AcuRite Galileo Thermometers is 100% paraffin. Parrafin is flammable so do not expose to extreme heat or open flame. The colored bulbs are filled with paraffin and 3.4% dye. The liquid is non-toxic. The dye inside colored bulbs may stain fabric. If the thermometer breaks, clean the area with warm, soapy water. More information can be found in the instructions on our website: http://www.acurite.com/media/manuals/00795-instructions.pdf Please let us know if you need anything else. Thank you.
this happened to me too, but it got thoroughly absorbed onto a stone fireplace, got on some cardboard and on some books and things, thoroughly absorbed and I do not want to throw them the books out. Does the residue of paraffin eventually wear out as far as the flammability?
