Misconceptions

• Referring to any sheet flooring as linoleum leads to misconceptions and improper care. Most modern sheet flooring consists of vinyl or other synthetic material stamped with color and design and sealed with a sealer. Damage to the design occurs when the protective seal wears off. Linoleum obtains its color and design from particles within the flooring itself. Wear does not remove the design or alter the color.
  
  

Types

• Hot water and strong cleaners easily affect linoleum. High concentrations of ammonia or hot water may degrade the bonding oils and result in yellowing or yellow spots. Dirt, residue or old wax trapped between a layer of wax and the surface of the linoleum causes the entire surface to gradually yellow. Objects, such as furniture or rugs, that restrict light from reaching the surface of the linoleum cause the surface to temporarily yellow or darken. Mats or rugs with rubber or synthetic backing create a chemical reaction with the oils in the linoleum, resulting in dark or yellow hues to the surface of the linoleum.
  
  

Effects

• Yellow or discolored linoleum detracts from the natural beauty of the flooring and prevents the original hues from being seen, but does not harm the linoleum. Cosmetic imperfections may not be a concern if the primary use of linoleum is to protect underlying flooring and appearance is secondary.
  
  

Considerations

• Remedying yellowed linoleum requires determining the cause and applying the appropriate action. Check that the floor is linoleum and not vinyl before attempting to correct the problem. Scrape a small section with a razor blade; if the pattern and color can be separated from the sheeting, the floor is vinyl. Color and pattern of linoleum will be consistent throughout the sheet.
  
  

Prevention/Solution

• Move any objects that obstruct light and allow the linoleum to be exposed to direct light to remove yellowing caused by lack of light. The hues in the linoleum will "bloom," creating a rich natural hue. Use wax stripper designed for linoleum floors to remove wax buildup. Yellowing and discoloration caused by the backing from rugs and mats is often impossible to remove, but may be lightened. Clean with a soft bristled brush and buff to a shine. To bleach the stain, mix a solution of one part household bleach with three parts water and cover the area. Allow to set for ½ to ¾ hour, scour to remove the satin and rinse with clear water. Neutralize the bleach with an application of ½-cup vinegar to 2 quarts of water. Rinse clean with plain water.
