Great for cleaning and removing those nasty odors, restores confidence to the surroundings.
By Lori
I purchased a used car in beautiful condition but with one drawback...old cigarette smell - yuck. I used the product and let it stay in my car for a full 24 hours. I was pleasantly surprised when I opened the doors to NOT smell any cigarette smell remnants! I'm hopeful the Biocide System solution will stick for the long term and the odor won't return or slowly creep back. But at this time, appears to have completely eradicated the issue. Thank you so much! Will definitely recommend it to others.

I love this product....our dog caught another skunk... this makes number 4 in 8 years... I have found Biocide and wow this stuff is great. Took the smell rite out of the house.... and now all I have to do is get the faint smell off of her. Thanks biocide for giving me my house back.

I tried everything!! Ozium..sprays...multiple times but could not get rid of the mouse whiz smell...I even used an industrial ion generator that I put in the car for days..no good... I was turned on to Biocide by a car detailer friend and put 2 in the car for 3 days....the smell is gone!! Gone!! Gone!! It's a pleasure to rave about this product.
