Question about particle board subfloor and pet urine. Was told to spray enzymatic pet urine cleaner and let it dry, then spray white vinegar (undiluted), let it dry, then spritz with baking soda dissolved in water and let it dry. Then I'm supposed to apply Kilz paint. Well I've done all except the paint, but the bakingsoda-water left a pale film when it dried. It doesn't brush away or vacuum up. Should I do an extra rinse with water? Or will it be fine since the paint is going on over it? And I'm also now wondering if the vinegar or baking soda will cause any structural damage to the particle board, even though it's all dried? Thoughts? TIA.
