Care and Cleaning
Adherence to regular and proper cleaning procedures is recommended to preserve appearance.
Scratched or otherwise damaged lens caused by misuse, mishandling and improper storage or
improper cleaning is not covered under the limited warranty.
Job Site Precautions
It is recommended the clock be removed from the wall and stored face up in its protective
shipment bag during painting and construction.
New construction and renovations frequently require that the job site be cleaned of any excess
mortar, paint, sealant, primers or other construction compounds. Only recommended cleaners
should be used to clean the polycarbonate lens. Contact with harsh solvents such as methyl ethyl
ketone (MEK) or muriatic acid can result in surface degradation and possible crazing of the
polycarbonate.
When the clock is first installed, glazing compound and masking tape adhesive can be easily
removed from the lens by applying naphtha (VMandP) or kerosene with a soft cloth, followed
immediately with a thorough soap and water cleaning.
Stainless Steel Case
If your clock has a stainless steel case, a cleaner and polish designed for use on stainless steel is
recommended. Use a recommended product to maintain and protect the stainless steel finish
while resisting water spots and fingerprints.

Washing to Minimize Scratching
Wash with a mild soap or detergent (such as 409™ (Clorox Co.), cleaner) and lukewarm water,
using a clean sponge or a soft lint free cloth. DO NOT USE PAPER TOWELS OR PAPER PRODUCTS
TO CLEAN OR DRY THE LENS. Rinse well with clean water. Dry thoroughly with a chamois or moist
cellulose sponge to prevent water spots. Do not scrub or use brushes or abrasives on these
products; the UV coating is not mar resistant. Also do not use butyl cellosolve in direct sunlight.
Fresh paint splashes, grease and smeared glazing compounds can be removed easily before drying
by rubbing lightly with a good grade of naphtha or isopropyl alcohol. Follow the alcohol rub with a
mild detergent wash with warm water and end with a thorough rinsing with clean water using a
clean damp lint free cloth.
