Congratualtions you have just discoverd some magical stuff. I swear by a a bit of Surfex it's incredible stuff. Just be careful of it's potency. 50/50 mix is a strong mix and never ever spray it onto a hot engine casing or it can leave a White residue that is incredably difficult to remove, the same with leaving to soak for too long. I use a 60/40 or even 70/30 the higher number being water for my general strong mix. I very rarely spray a neat mix on anything. If I'm cleaning something like thick grease from behind the front sprocket cover I may use a slighlty stonger mix to get rid of the worst. It can be watered down to about 90% and still work as a genral surface cleaner, work surface, wiping tools down or something. I have used on thick grease, paving slabs, carpet and as a weak solution to remove wax and any previous coatings or bugs on paintwork. Iv'e even used it to wash my greasy hands. I'm sure helps break up any grease down the kitchen plug hole

Actually Iv'e even used it to clean the kitchen sink. Be careful of it's use on plastics too especially Black plastics. Make sure it's a weak solution if you do. What it doesn't like is being applied to hot surfaces.
A stiff brush like the following is handy for getting in and agitating areas to help break up the grease. Fantastic on engine casing's, shock spring / linkages, wheels etc. Even after fitting CCT's and there is loads of overspill of silicone or gasket sealant once all tightend up, a little spray of Surfex and off it comes.
