Cleaned my bike and wanted to detail it with Lemon Pledge but forgot that I had run out last week. The wife picked me up a couple of cans so later that day I started to use it. I noticed that it wasn't clearing up on the paint and kind of leaving streaks. I tried the other can and the same thing was happening. My brother brought over his, tried it and it was OK?? I called the company and asked them if they had changed the formula recently and they said yes. The formula was changed in Jan of this year-2012. The person I was talking to said that if you look at the back of the can about 1/2 way down there is a white banner and inside that banner it says "contains no petroleum products". If the can has that on it is the new stuff. I went to a number of hardware and grocery stores and could not find any that did not have that that phrase on the back of the can. I did find 6 of the old stock in a few corner stores and will be buying more when ever I see it.
