GOOF OFF is another cleaner sold at most hardware and drug stores works 
great but like those listed below note the WARNING labels:
These product contain chemicals known to the state of California to cause 
birth defects or other reproductive harm.

"Vapor harmful," the labels read. "May affect the brain or nervous system 
causing dizziness, headache or nausea.... May be harmful if absorbed through 
skin.... Do not breathe vapors.... Do not get on eyes or skin or clothing."

These producs contain chemicals that have been associated with birth 
defects, toluene and xylene. Both substances can cause kidney and liver 
damage. Both can be absorbed through the skin as well as by breathing the 
vapor.

Children are more vulnerable to toxicants absorbed through the skin because 
of their relatively larger surface area-body weight ratio, the federal 
Centers for Disease Control and Prevention notes in a xylene report.

So, wear gloves do the work outside and this one is probably not a family 
project!

Have Fun and Be Safe
