Before I got my VR, it had sat for a very long time and had gunk all over it. Last night I decided to put the windshield back on but first had to clean it. I took it in the house and put it in the bathtub (the wife was proud of me:whistling:) and thought it would be a easy job. After some gentle cleaning with mild soap, I still had a film on it. I am pretty sure it is tree sap. Is there an easy way of cleaning it that won't damage it. I've tried dish washing liquid. I know windex isn't recomended but I tried it on a small area but it didn't help either. I am able to scrape off with my finger nail so I know it should come off. Any ideas? The seat also is covered with what is probably sap, although, it actually looks like tar.
