There was no Google Earth back then! Anyway, is there some kind of Armor-all like product for vinyl siding that freshens it up a bit after you wash it? I am going to need something because I don't want to reside the house before I sell it this summer.

This is an interesting thread - whilst I agree that the distinction between "chemical" and "non - chemical" may not be the most useful one (for the reason pointed out above) - maybe a more useful discussion is about harmful and less harmful cleaning substances, whether to the environment or people. I suffer from something called MCS ( multiple chemical sensitivities, it's a diagnosis) and have come to realise that in my case at least it's not chemicals per se that make me sick, but rather certain smells. For example I cannot have the "Earth choice" (a natural") brand floor cleaner used in my house without suffering a few days of sore eyes, nasal congestion, fatigue, foggy brain and sinus headaches - it is truly debilitating, and the cause is the fragrance. If I use the same brand of "Naked" ( no scent) dish cleaner diluted on the floor instead, I am fine. I think everyone with MCS is different but this is working for me.

Natural stone floors need extra care.

In the event of discoloration: use coordinated special cleaning agents. Travertine does not go very well with acidic cleaning and care products.

Use a layer of wax build-up to protect the natural stone. When cleaning the travertine for the first time after grouting and laying, it is better not to use cement film remover. Instead, work with a basic cleaning that removes the stain and another soiling effectively and gently. As already mentioned, the basic cleaner can also be used wonderfully for everyday care.
