Removing Film On Windows From Painters

I have my own window cleaning company and have had problems lately. When painters use their spray on protective coating to paint around windows, when removed, it leaves a greasy film. After I have cleaned the glass there is still a film when you look through the sunlight. Is it a possibility that this protective coating is actually ruining the coating of the glass, or is there a safe way to remove it without harming the glass or its coating? I have tried different solutions, scrapers, 0000 steel wool, etc. My builder, painter and my self are all baffled. I’m looking to someone who may have experienced similar problems. This is not good for my business, since everyone is looking to me for answers.

Removing Painters Film From Windows

Below I will give you instruction on what works for me but first I need to give you my full opinion of this type of situation. I think this is just out right sloppy and unprofessional workmanship on the painter’s part because they don’t take the proper time to cover the glass that they are spraying around.

I understand where you are coming from when you say you are worried about your reputation as a professional window cleaner. You should not worry because you did not cause what I consider damage to the glass due to the sloppy work of the painters.

There are three approaches that you can take to protect yourself in the future.

• Before you start cleaning the windows you want to show this mess to the person in charge and explain that this could have been avoided if the painter would have taken the time to properly protect the glass. You as a window cleaner can only do so much as not to cause more damage to the situation but, you will do your best and there cannot be any guarantees.

• Second, again before you’ve started cleaning windows, you can explain to the person in charge that this is actually considered window damage that could have easily been avoided and that since the painter caused this they need to fix it at their expense. You do not want to be responsible for causing any damage to the glass that may occur during the process that it’s going to take to get the windows back to their original state.

• The third approach is sometimes it’s cheaper in the long run to not take a job like this because the window cleaner always gets the blame if there is any damage to the windows or if there is unsatisfactory towards the window cleaning job.

Removing the Over Spray

I’m only guessing but usually the final coating is a type of lacquer. I doubt that this protective coating is hurting the glass it’s just hard to remove.

What has been successful for me is using a product called Sani Scrub. Below you will find a link to the product. Once the top layer is scraped off you will want to then re-wet the glass. Squirt a dab of Sani Scrub onto a wet towel and hand scrub every part of the glass. Then you have to rinse the Sani scrub off. Then with a clean wand and fresh window cleaning solution, do a final clean. I know it’s a lot of extra work but it’s the only way to get it off. Sani Scrub is a mild abrasive liquid that works wonders on just about anything, it’s a main part of my window cleaning tool box.

I hope that helps.

P.S. I’m assuming that you already are aware of clean tempered glass but, just in case you don’t, you might want to check out my page on cleaning tempered windows. A lot of damage can happen to tempered windows during construction window cleaning.
