<b>Guy'ly bum I didn't know they still made those wittle bread trucks the ones around here willl take alittle longer to do cuzz they wittle bigger.
They are alot of good soaps out there,the one your useing may be O K.What most make a mistake at when useing any chemical is getting the right formular mix for it to work.Some of these newer breeds of chemicals want work near as good if to strong,I know it doesn't make sinces but it seems to go againest the cleaning power if mixed to strong.Then again most users do not mix it strong enough for it to work.
Your mix may not be right for it to work on the bread trucks,depends.How offen they wash will have a effect on how to mix your chemicals for it to work on them,the type of paint will have an effect on what kind of chemical to use.Try adding to your mix your useing now to see if it will work,if it turns out costing to much to use it find another.
I just orded a new chemical which cost $30 a gal. its ok but will cost to much for me to use on each truck,I have some tho I can use it on and the cost is about the same as the others but still it has its advance in some cases.
Meaning,,Most good fleet soaps will clean just as good as the others if your mix is right,,Some take alittle longer to work then other,some will remove what others want.If the bread trucks are washed ever week you don't need a super dupper chemical to clean them but if monthly look for that supper dupper and to get it mix your soaps as strong as need be,,,,,you want find that mix on the label of the chemical your useing.</b>
