19.  Cleaning Tips for Guardian Telephones 

Guardian Telephones may occasionally need to be cleaned to maintain appearance. Generally, 
wiping the surface with a clean, water dampened cloth will remove most films or residues. If the 
soiling is too stubborn for plain water, a mild detergent solution may be used. Be sure to wipe 
away any detergent residue with a plain water dampened cloth. The Telephone may be cleaned 
with any general-purpose household glass and surface type cleaner. Do not spray the telephone 
directly! Spray the cleaner on a soft cloth then wipe the surface. Pre-treated cloths, like those 
used for eyeglasses or cameras, may be used to clean the Telephone. Premoistened towelettes 
may also be used, however, avoid those containing lanolin or aloe as they will leave a slippery 
residue. The handset and surface of the telephone may be cleaned with disinfectants used for 
general cleaning in a medical environment. Isopropyl alcohol may be used applied with a cloth. 
Avoid using alcohol on silicon based keypads, since doing so may significantly degrade 
legibility. 

 

Do not use furniture polishes, waxes or plasticizer-based cleaner (Armor All etc.) 

 

Do not use lanolin, aloe, glycerin or other skin care type products. 

 

Do not apply any solvent such as acetone, mineral spirits etc. 

 

Do not directly spray or immerse the handset. 

 

20. 

Storage 

 

General Storage (All situations): 

  Note any stacking limits or warnings on packaging (if any). 

  Do not store in temperatures over +80C. 

  Store in original packaging if possible until needed. 

 
Long Term Storage (> 6 Months): 

  If area is air conditioned and not subject to high changes in humidity, continue to store in 

original packaging. 

  If wide humidity shifts are expected, then use these steps: 

o

  Remove product from packaging (including plastic bags) and store on shelf in open air. 

o

  If area is subject to a high degree of dust, to help maintain cosmetic appearance you can 

cover with cloth (Do not cover with plastic or materials that will trap moisture) or clean 
periodically. 

o

  Do not store out of packaging long term where they are exposed to sunlight. Long term 

exposure to UV may cause fading on plastic parts.
