Water Marks Leaded Light Window

[Dabber]

Did a first clean on this house, no problems. Did a second clean and got called back so went over it again and still these water marks are visible. Any ideas ?

unger rub out and plenty of elbow grease should sort it out. Charge well for it though as it may take a while. It would’ve been better for you if you could’ve pointed it out on the first clean though as they could suspect that you’ve caused it and may want it included in with your regular clean price.

Everything was fine on the initial clean so didn’t expect any issues going forward. He’s going back to cleaning them himself now so no bad feelings but I just wanted to understand what’s happened with the marks/ stains.

Looks like someone’s been outside with a pressure washer or hose pipe as that looks like limescale spots to me.

Hard water stains. Hosepipes, pressure washing, hanging baskets all cause it.

It's the lead on the window, it's supposed to have a coating on the lead but on some leaded windows the coating has been removed exposing the lead, when you clean with the purified water it absorbs the minerals in the lead and the water is no longer clean, it's contaminated and therefor dries as if you have just cleaned them with tap water, actually it's worse than tap water...

You can use bar keepers cream to remove it, I've never used unger rub out but you can try it. But moving forward this window will do this every time you try and clean it. I've got one on ground level, just two windows and I clean them normally but dry them immediately after using kitchen roll, if I don't dry it thoroughly and carefully then they look terrible.

If I had a whole house like that then I'd just tell them it's not possible and explain the reason why.

We clean loads of leaded windows with some really poor lead on them and never had a single issue with any mineral deposits on the glass . But here’s the strange thing we have many conservatories that have lead flashing going onto the glass roof and the mineral deposits on the roof are horrendous, but it’s not sports it’s dark long lines that you can feel raised on the surface of the glass
