Just wanted to pass along a recipe I received while on a trip to Colorado Springs a few years back. I still use it today.
16 oz Turtlewax
32 oz Distilled Water
1 oz Lemon Juice
1 oz Palmolive, Dawn or Joy
Mix together and wax/clean away.
Just an FYI use a good container to hold mix in. I made mistake first time around of using an old milk jug and the mix eventually leaked. So I use an old windshield washer jug to store it in now.
Also the gentleman I received the mix info from was using it on his fifth wheel and said he got it from a retired chemical engineer.
I've had good luck with Turtle Wax Bug and Tar Remover, just got back from the Grand Canyon and every few days during the trip I'd use it to keep it from getting too bad. I will try your formula though, the love bugs down here in Fl. sometimes take a lot of elbow grease and maybe it'll make it easier. Thanks.
