Window cleaning tips and advice from www.allcleanservices.co.uk
1. Removing egg stains from glass.
One of the most difficult tasks a window cleaner has to deal with is cleaning windows that have had eggs thrown over them, (this can be almost impossible if the egg has been baked on by the sun)
Unfortunately this problem is becoming more and more common, especially if the window cleaner is working on schools and colleges.
All Clean Services Ltd clean schools and colleges across London and the South East UK so this is a problem that we have to deal with on a daily basis.
After many years of experimenting our window cleaners have found the best way of removing the egg residue is as follows.
Soak the affected surface in a diluted mixture of Powerzest and water, 10 parts water to 1 part Powerzest, let the solution soak in for 5 to 10 minutes then wash the glass in the normal fashion. This will leave you with nice sparkling windows (until they are egged again that is)
