Simply pick the cleaning cap size that fits your glass perfectly, add your favorite cleaning solution, secure the cap, and shake! It’s that easy to achieve a sparkling, streak-free clean in seconds.

We invented these caps for our glass company, Prism, and thought, hey! these work damn well for all types of glass.

3 cleaning caps in varying sizes of 2.75”, 1.75”, and 1.25”.

All cleaning caps are made of a stretchy high grade silicone for a watertight seal.
