  1. I have removed old window tint from a lounge window, it was quite brittle and the top layer came off but has now left a cloudy look on the window. I have tried eucalyptus oil, method and hot soapy water but still not coming off. I have used a razor blade for a small bit but at this rate it will take for ever. Any Suggestions?

  2. I have sprayed an outdoor setting with high gloss white Dulux Metal Shield Epoxy Enamel on a windy day and the part of brick pave not covered by newspaper has become a lighter shade. How do I remove this?

  3. Hi Dr, thanks for yr wealth of solutions – an interesting read.
    My Q is how to revive a faded ‘charcoal ‘ aluminium pool fence? It’s design is thin tubular uprights & would make it quite tedious (@ least 40mt in length) ?
    Thanks

  8. Dear Mark,

    Can you please advise me how to remove window tint glue from a fabric car seat. We stripped the tint off some windows and a small piece (approximately 3mm x 1mm) of the sticky glue got stuck on one of the seats. We tried white spirits but the glue is still stuck in the fibres.

    Kind regards,

    • Hi Dr Chemical. How can I effectively clean the inside of my car windows? I have used Windex, Metho, Washing liquid, Bleach, Glen20 and just about everything known to man but I am always left with a foggy smeary window. I am a driving instructor and it is driving me crazy as I need a clear view when driving.

  9. Hi there – I am unable to find soda ash in any supermarket except the stuff used to balance the pH in pools and spas – is this the same product? This is for cleaning grout on the floor tiles.
    I have also found a product called ‘Grout King’ – it contains 350g/l phosphoric acid – works like a treat but I am wondering how much damage its causing?
    Cheers
    Jac

    • Yes that’s the right stuff. But you get it from supermarkets at ankle height in the cleaning aisle – it’s a bit hard to find. Where did you find the Grout King – I can’t find any info about it anywhere
