This tip about not cleaning windows when its too hot is probably common knowledge for a streak-free result, but I hadn't heard of using cornstarch before. Anyone tried it?
Jason, my builder and his wife (who cleans up the worksite before handing over to the client), swear by Morning Fresh dishwashing liquid and after seeing how it worked on our windows, I would have to agree. We've got a kajillion windows in our new reno at Culburra plus those louvre ones (pain in the a*se to clean) and they've come up a treat.
Mrs Henno has come up with an invention to clean the louvres which involves a pair of BBQ tongs and some sort of car washing cloth. It's in its first iteration, so only early days and trials are ongoing.
But back to your question about cleaning windows: I would have to agree with my builder's wife (Tina The Cleaner) and use Morning Fresh with some washable towels.
However, having said that, my Mum did swear by newspaper and metho. But as my friend Andy_Mann says, you should only mix metho with orange juice...
Thanks for sharing @Henno. Must try that. But I'm most curious about what the BBQ tongs are for when it comes to cleaning the louvres!
Good to see you posting again.
I've never heard of using dishwashing liquid on windows before. I assume you would only use a very tiny amount?
