Can I remove spider poo, flies and mosquitoes from my tarp?
With Ultramar Sail Cleaner it is generally no problem to remove stains from spider poop, flies and mosquitoes from a sail.
Yes, in general that is not a problem with Ultramar Sail Cleaner.
We always soak a sail with such stains in the Ultramar Sail Cleaner for a few days in our special sail washing facility.
After 1 day of brushing and rinsing the sail, we let it soak for another 24 hours. In general, that is sufficient. You can repeat this treatment several times if you wish.
