Concrobium looks like some cool stuff Dave ...that being it's non toxic
looks like it'll cost 9.99 from manufacturer
where as the zep formula was only 3 bucks
household bleach is only 5% strength where as swimming pool chlorine is
like 99% strength and is some real nasty strong stuff burning holes
in clothes quite easily... i got some splashed in my eyes once
i've never run faster in my life to a sink
