Thanks, ribit. I may give it a try.
DO NOT UNDER ANY CIRCUMSTANCES USE THE "FULL STRENGTH BRANDS" They will remove skin. A woman I know had a sore back and her husband brought some full strength stuff home. It is a liquid like water. She lay on the bed face down while he poured it on the lower part of her back. Like water this liquid tends to run down hill. Can't tell you exactly where it went, but they are no longer married.
I am trying to imagine where it could have ended up.
Could have caused a brush fire of sorts. Ya think?
If you think education is expensive, try ignorance.
