My friend has been wondering, all the people that he heard about on here that are using d-Limonene .. how are they disposing of used limonene? He also asked if its possible to reuse it in some way.. he assumes it would be need to be distilled tho and he is just an amature kitchen chemist so thinks that is prob not an option.

Although it is diodegradeable, it is also apparently toxic in its pure form and degrades quite slowly so he does not want to just pour it down the sink..

I've been pouring mine down the sink, though it did occur to me that it might not be a good idea. I'm curious too.

You could keep it in loosely capped jars next to a litter box or in a garage as an air freshener. I wonder how much limonene is released into municipal water systems by all the orange peels going into sink garbage disposal grinder thingies.

Swim works as a machinist an his clothes get very dirty, so he uses the used up limonene in the pre cycle in the washing machine. his clothes come out very clean and degreased and they smell great.

nice tip, thx

D-Limoniene is sold in most cases as an (industrial strength) cleaner & there are instructions right on the bottle of High Purity D-Limoniene that I have here, for diluting it with water for household cleaning chores.

So I have been pouring it down the sink drain too, but I usually dilute the hell out of it with hot water before doing so.
I'll add somewhere around 3000 parts water to 1 part D-Limo, to where I don't even smell the orange-ish scent anymore.
No issues yet, although I imagine these kind of problems do not show their faces right away...

BTW, my sink is always nice & clean when I'm finished too.

Here is a link to the greenterpene.com "Applications" page, where they list dilution ratios for different uses, just to give you an idea.
