Clean fittings, tub, washbasin with oven spray
I was annoyed for a long time about the dear family, which does not use liquid soap. With conventional soap bars that contain a lot of fat, an unattractive wax-like coating forms in no time, as the fat immediately hardens in cold water or on the cold pool.
The mess you see exactly when you have to clean the trapper, because everything sticks to it and also contributes to the constipation. With oven spray you get that great again, because it has a high fat content. Spray overnight on the lubrication points and something in the sink, help with a brush the next morning. And then quickly hide the soap bars! :)
