How to get the smell of fish oil out?

Cat urine.

Really though try; Natures Miracle.

Here is link to it on Amazon or if you have a Trader Joe’s near by you can purchase it there. We have a home full of animals and we are sensitive to smell. This stuff rocks.

after i clean fish i wash my hands with palmolive or something strong then i take a fresh lemon and rub that in real good rinse repeat. maybe a good soak in lemon juice concentrate might help.
