I know what the website says, the facts are it is a serious chemical
solvent and should not be used in a enclosed area without good ventilation. It does not penetrate it softens the finish the first ingredient in it is actually used in some strippers.
I am not promoting one product over another I actually think vinegar and water is a great safe cleaner. I just posted what my DH with over 30 years expierence as a furniture restorer, he is not a refinisher, he is a craftmans who has restored pieces for museums, uses to clean quality antiques.
I am not saying you should not use Howard's but I think an informed consumer is a knowledgable one and with that knowledge can make a informed decision on what is right for one's family.
This is what Howard's contains:

Methyl ethyl ketone
Methyl ethyl ketone is used as a solvent. Acute (short-term) inhalation exposure to methyl ethyl ketone in humans results in irritation to the eyes, nose, and throat. Limited information is available on the chronic (long-term) effects of methyl ethyl ketone in humans. Chronic inhalation studies in animals have reported slight neurological, liver, kidney, and respiratory effects. No information is available on the developmental, reproductive, or carcinogenic effects of methyl ethyl ketone in humans. Developmental effects, including decreased fetal weight and fetal malformations, have been reported in mice and rats exposed to methyl ethyl ketone via inhalation and ingestion. EPA has classified methyl ethyl ketone as a Group D, not classifiable as to human carcinogenicity
