When working on old electronics, you often need to clean gunked up switches and pots that are difficult to get to. Aerosol cleaners come with a little straw to direct the spray, but many times you can’t get the can where you need it to go, or the angle is such that spray doesn’t end up where it ‘s needed, or there is a lot of waste and excessive fumes. The solution is a little flexible tube with a stick on the end so you have a handle to direct the tube end in tight spots. The spray can straws are sold on Amazon by many sellers. Here’s one: https://www.amazon.com/dp/B09K3T496C
The holder is any stick-like object with a hole drilled in the end. A chopstick would be perfect, but I didn’t have one at hand.

Great Idea. I ordered some. After I get it I may try to create a stick with my 3D printer to do that. Maybe more than one stick at different angles.

I always cut the tube they gave you with the spray in half and reconnected it with a 6-8 ” piece of heat shrink tube . on the business end of the tube I sometimes to a match under it to get a 90 degree bend in it .
