So if you clean it late at night and let it sit in a well ventilated area till morning, that should also suffice. **Q: Is k&n 99-0624 synthetic air filter cleaner to be used on ru-3102hbk universal air filter?** A: Yes...use it on any oil-free synthetic filter. I use the AEM Dry-Flow filter, but it is made by K&N. Do not use citric degreaser products as those will clean but will remove the color in the filter. You can also use AEM 1-1000 Dry-Flow filter cleaner. **Q: New to Amazon and bought this air filter cleaner and it all leaked out or was busted and the boxes wet what do I do** A: Request replacement from Amazon! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by A***R on December 2, 2025* Cleaned both my k&n filters great.
