If your water is hard, you are not keen of thorough cleaning every time using it, you frequently knock over stuff... , Like i do, Forget about it. It is the most difficult surface to clean. But I do have the secrete cleaning tips if you insist on it.

@cyqi I would like the secret cleaning tips. I don't have glass counters, but I may in the future!

Ok. For those how are interested in cleaning, here is my tips. In hard water area, Clint Bang is a must have (red cap, note other color won't work for lime scale! I know it really smell...). It works even on tough lime scales. You need original E-Cloth microfibre cloth. Note only E-cloth, other bands although claim as microfibre won't work as good as E-Cloth (or I can say, no way to compare). You will need both the one for general cleaning and one for glass and polish. Use Clint bang when there is lime sacale accumulation. Spree the surface, stand for one min then wipe off use general cleaning cloth and rinse with water. Then use dry glass cleaning cloth to remove the residual water and shine. If there is no accumulation in lime scale, the glass cleaning cloth will do the job. You need it to be dry. If there is mould accumulation in the grout, silicon seal, use Dettole mould and mildew remover. Leave as long as possible untile the mould is completely gone. Don't follow the Dettole instruction. These are results of my testing of most of cleaning products in the market. I'm a busy working mum who do not have time for very regular cleaning, used to live in houses with extreme hard water, damp, a lot of glass (including kitchen and bathroom) and designed and renovated several kitchens and bathrooms. Hope this will work for you too! One more tip, The Dettole mould remover works on tough stains on white wall too. It bleached my wall beautifully once my mum splashed black hair dye on my white bathroom wall.

Thank you!!
