7 Bubble Handling and Cleaning
The bubble is made of Polycarbonate. This material provides high impact resistance. It’s
optical clarity is comparable to glass or acrylic, although it’s surface is much softer. Special
care is required when handling and cleaning the bubble to avoid scratching it.
7.1 Handling
The bubble is packaged with a protective plastic sheet. It is recommended that the bubble
remain stored this way until it is ready to install. Limit handling the bubble, as any scratches
can quickly affect visibility.
7.2 Cleaning
If cleaning the bubble is required, use the following procedures and comply with all the
warnings listed below.
7.2.1 Cleaning the Bubble Interior
The extremely soft interior surface should not be cleaned by rubbing or dusting with a cloth.
Use clean dry compressed air, preferably from a spray can, to remove any dust from the
interior surface.
7.2.2 Cleaning the Bubble Exterior
The exterior of the bubble is hard coated for extra protection. If cleaning becomes necessary,
only use cleaning solutions and cloths suitable for cleaning safety glass lenses. Dry the bubble
thoroughly with a dry nonabrasive cloth to prevent water spots. Never scrub the bubble with
any abrasive material or cleaners.
Do Not:
– Do Not use abrasive or highly alkaline cleaners on the bubble.
– Do Not scrape the bubble with razor blades or other sharp instruments.
– Do Not use Benzene, Gasoline, Acetone, or Carbon Tetrachloride on the bubble.
– Do Not clean bubbles in the hot sun or on very hot days.
WARNING!
Do not use alcohol-based solutions to clean the bubble. This will cause the polycarbonate to
cloud and over time cause stress aging, which makes the bubble brittle.
