If you did not protect the plastic frame during repair, you should remember that it is not so easy to clean it. It all depends on what kind of pollution we face. First of all, two types of stains should be noted: surface stains from building materials and persistent stains (discoloration or pigmentation of plastic). The most common surface stains are all kinds of residues that are used for interior decoration, starting with plaster and ending with paints. Taking into account the degree of complexity of their removal, somewhere in the middle you can put the paint, at the same time persistent stains can create serious problems, since the fight against discoloration, at least two levels of difficulty will be higher. Another thing is that often discoloration (pigmentation) can be the result of improper removal of normal surface spots.
First aid: warm soapy water
First of all, you should make sure that the existing dirt on the white plastic Windows can not be removed with warm soapy water. A significant part of the pollution can be dissolved in the case of such "bathing". Prophylactically, the cleaning process should always begin with the use of water with soap or dishwashing liquid. This is a very good solution because there is a very low probability of damage to the surface or the risk of discoloration of white frames with soap solution. Thus, it will be possible to get rid of at least some persistent stains. In addition, warm soapy water will slightly soften difficult to remove stains and dirt, so that later get rid of them will be easier.
