Safe Removal of Bird Excrement

To safely remove bird excrement without causing scratches to the paint protection film (PPF) surface; use a solution of Optimum no-rinse (ONR) diluted 1:20 / distilled water in a fine mist spray bottle) and allow to remain in place as this will soften debris and allow it to be removed. Use very little surface pressure, dusting with long strokes in one direction only, this will lessen surface scratching as they ‘lift’ dust etc into the media

Use a long nap micro fibre towel to ensure the debris that is lifted from the PPF surface remains in the nap and not on the towel surface thereby causing surface marring. Shake the towel occasionally to ensure any particles picked up will drop out rather than come to the surface while you’re using it.

Do not scrub hardened/dried excrement residue, birds use gravel to help digest their food so grit and sand are some of the major components, which can cause scratching as it is very abrasive and will scratch the PPF surface.
Once it softened (re-liquefied) it enables their removal with less likelihood of damage to the films surface. Do not use on a hot paint surface (soon after driving) as this will cause streaking

Thanks for the information TOGWT but I was referring to when the bird poop leaves an actual stain on the Ventureshield. I read that you can use a hairdryer to heat the film for a short period and it makes the stain dissapear?

good question..I have some "stains" on my clear bra too. Can't tell if they are actually dings from a rock hitting or if they are stains from bugs.

IF you decide to heat the ppf, don't do it long. You can cause damage if you put too much heat to hit.

Satins – to remove stains from PPF surface use a safe solvent (P21S Total Auto Wash, a d-limonene (citrus) based cleaner. Do not scrub hardened/dried excrement residue as it is very abrasive and will scratch the surface, once they are softened (re-liquefied) it enables their removal with less likelihood of damage to the PPF surface
