Depending on what area of the country you live in, spring can often bring the onset of humidity and as a result, mold can certainly become a pesky factor in homes when that happens. 

According to the US Environmental Protection Agency (EPA), good tips for removing mold on non-porous materials are: 

• Remove any obvious moisture from the area.
• Fix any plumbing leaks.
• Isolate the molded area from the rest of the space it has infiltrated.
• Thoroughly scrub mold off of non-porous materials with soapy water or Timbor. Thoroughly dry the area after scrubbing.
• Dispose of any and all porous materials that were used to clean or any carpets and coverings that have come in contact with any mold.
• The cleaner should be wear protective clothing (full sleeves and pants) as well as an appropriate mask with a strong safety rating  to avoid breathing in damaging spores.
