a very superficial stain ( rd color of the petters0 tried, detergent,

Proctor and Gamble has a new product called Cascade Plastic Booster.  It is
designed to remove red lycopin stains from plastics.

i dont know if this went through so reposting it

got the cascade plastic boost--seems to be mainly benzoyl
peroide--smeared it on stain no results--mixed it with cascade powder
and will see what is left in am

incidently tried sodium hydroxide to no avial

I have to ask...  Is it that earthshatteringly important to rid this
workbowl of the stain?  After all, it *is* a *work* bowl.  For what you're
paying in cleaning products, you'll soon be able to buy a replacement.

As a long time user of food processors, I have to stay that while I've
never had a stain, my bowls eventually turn almost frosted from the
abrasion chopped hard foods like nuts, frozen cranberries, etc.  It's an
expected condition that I have no problem living with.

i agree it is not a major problem other than understanding the chemistry

i kind of aggravates me to have a bowel ( it is in front of a white
refrigerator) that has a red strip similar to that of the titanic--also
if the bowel is capable of being stained it also suggests that the bowel
cannor bve disinfected--i would never process chicken in it now

I think almost anyone would find this aggravating!  (sorry, Peter, I
couldn't resist)

FWIW, there may have been some kind of chemical reaction that caused the
stain to set so indelibly.  Not a matter of permeating below the surface of
the plastic.

If you wash your f/p parts in the dishwasher, I wouldn't think that
processing raw meats would be much of a hazard.

read up on beta carotene--probably what is causing the problem--it
reacts with oxygen to form a ...colorless compound--merck index

planing on playing with high concxentraion of hydrogen peroxide
so;utions found in hair bleaching products---some i believe can be over
30 % peroxide--i believe the Germans used something like this to fuel a
submarine!!

tried the plastic booster--benzoyl peroxide--made paste with cascade
dishwashing powder--took most of it off overnight will repeat it

looked up the chemistry of lucoprene--beta carotene--bonds look
difficult to break--suspect alkalinety of powder releasted hydorgen
peroxide from benzoly peroxide and that 's what did it

interesting stain to remove

Try this. Don't know about chili pepper dust, but it works great on
other stains and scratches on Lexan.

By the way, it's "bowl" not "bowel."

i tried pumice to no avail--i think what happened is that something got
caught between the edge of the blade and the bowl and the pepper
material actually got welded into the plastic from the heat

i dont know if i posted what worked but plastic booster with paste made
of it and cascade dishwasher soap took iot off after 2 attemps
overnight--plastic booster says copntaions benzoyl peroxide--merch index
for beta cartotene says it turns colorless when exposed to oxygen

fwiw
