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

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.

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

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

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

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.

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

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
