This prevents scratching the surface.  <\/p>\n<p>Plastic spatula \u2013 for carefully removing dried dirt.<\/p>\n<h4>What to Avoid<\/h4>\n<p>When cleaning PVC frames, never use:<\/p>\n<p>Solvents and aggressive chemicals<\/p>\n<p>Abrasive cleaners<\/p>\n<p>Wire brushes or sharp objects<br \/>These agents can corrode or permanently scratch PVC. Be especially careful with solvents if you have PVC windows with lamination (a color other than white). <\/p>\n<h3>When Cleaning Doesn&#8217;t Help<\/h3>\n<p>It is important to know that in most cases, yellowed plastic windows are a result of material degradation due to sun exposure and age. This particularly applies to older windows. In such cases, the original white color cannot be restored \u2013 the only solution is to replace the frames. Today&#8217;s white PVC profiles are much more resistant to degradation from sun exposure. They contain stabilizers that protect them from the effects of UV radiation, ensuring their whiteness for many years.     <\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yellowed plastic windows are a common issue for both apartment and house owners.
