bangkokairportlink Posted July 4, 2017 Share Posted July 4, 2017 Hello, When spraying the car but not drying it, I get some limescale that usual car wash, even expensive ones, are not able to clean. It seems that white vinegar with water is enough, have you tried it ? Do you think it can remove the glass coating that has been applied on top of the painting ? Any other solution ? Thank you.

rickb Posted July 5, 2017 Share Posted July 5, 2017 I use white vinegar and dish washing soap (half and half) with a sponge and it takes the calcium/magnesium scum off very easily. I use it in my shower and bathroom sinks frequently without any problems. I don't see why it wouldn't work on a car. Link to comment Share on other sites More sharing options...
BuaBS Posted July 5, 2017 Share Posted July 5, 2017 It's very hard to get them out without damaging the paint. The sun burns the dirt onto the glass windows of the car too. No vinegar is going to get them out. ( I've tried it too) When your car is wet after the rain (or just washing it in the full sun) , and the sun comes out again , it burns the polluted water in the paint & glass. Now I have bad paint ( isuzu ! ) ... but even in the glass ! Link to comment Share on other sites More sharing options...

So I am sorry but I do not believe your story. If it is written online then it must be true............... I can 100% guarantee that the vinegar solutions do not remove these hard spots from auto glass once they are ingrained in to the glass, I spent hours upon hours trying to remove some extremely annoying and stubborn ones from all of the glass on my car, not a hope, I had blisters from trying! I even tried ceramic hob cleaner, as that can remove some spots on glass. Ended up buying some special stuff from Lazada, was imported from Malaysia, sorry, not sure of the exact name as not home at the moment. This stuff came in a small plastic bottle with a sponge, when applied it did remove the spots relatively easily, there are no ingredients written on the bottle, but I suspect that it may be a very weak solution of hydrochloric acid, as it has that distinctive smell to it. I tested it carefully prior to using it, including on paint, seemed to be no issues. I reckon it depends on how long you leave the spots for before trying to remove them as to how easily they come off. Oh, tried the clay bar route, no expert on these, but as the glass has some very small pits in places, then that did not work out well at all!

bazza73 Posted July 5, 2017 Share Posted July 5, 2017 It depends on what the limescale is. If it is primarily calcium carbonate, vinegar ( 20% acetic acid ) will remove it very nicely. If it's calcium sulphate, neither vinegar or hydrochloric acid will be effective. EDTA ( a complexant ) will remove calcium sulphate scale. IMHO hydrochloric acid is a bad idea. It won't attack paint in dilute form; however, if it gets into any crevice in a vehicle it will sit there creating a corrosion cell. Pitting of glass may possibly occur if the lime scale contains calcium hydroxide. At elevated temperatures, being alkaline, it MAY dull the glass surface by reacting with silica.

The water I use in my house is from a deep bore and is not really nice to glass, I had two additional bedrooms with ensuite built a couple of years back, the showers are glass enclosures, they are almost impossible to keep clean. By EDTA then do you mean Ethylenediaminetetraacetic acid? Can this be purchased in Thailand? Link to comment Share on other sites More sharing options...
Madgee Posted July 5, 2017 Share Posted July 5, 2017 I live in a mains supplied hard water area. Whenever I wash the car I make sure it's in the shade and always chamois it as not to leave streaks and water marks. If it rains and the car gets dry in the sun, I just use dampened old newspapers on the glass and bodywork to remove the marks left by the rain when I want it to look 'clean' again. I think I read somewhere that the print or paper contains a very mild acid. I've tried many different car washing products (expensive ones as well) and the best so far is Tesco Wash & Wax! Very little wiping to do on the bodywork after a wash and seems to dry virtually streak free. It also removes previous water marks from rain. Sorry for this but if your car is glass coated you shouldn't have a problem. Link to comment Share on other sites More sharing options...

Yes, I meant Ethylenediaminetetraacetic acid, although being lazy I omitted to specify it's the disodium salt. Chemical supply houses in Thailand should carry it, it's used in laboratory analysis and water treatment. In Chiang Mai, there is a chemical supply shop opposite Nimmanheimen Road in Suthep Road. Bear in mind your shower glass is filming up because the calcium/magnesium in the water is reacting with the fatty acids in the soap you are using. If you put the bore water through a water softener which exchanges calcium/magnesium for sodium, your problem should go away. Link to comment Share on other sites More sharing options...

This topic has just reminded me that I had forgotten to do the second half of the glass roof on the Everest. I did the first half about nine months ago now. Previously, I had initially tried HG Professional Lime Scale Remover, but it didn’t have any effect at all ... now I understand why ... so I purchased some GETF1 Water Mark Remover from a seller on Thai Washer Car Club and that remover the water marks. So, fearing the worst, I went out and used the GETF1 on the second half of the glass roof and it only took about ten minutes to remove all, including washing the glass roof and wiping over with APC. I was concerned that it might have etched a bit. The first half is still looking okay … just … I put some Si-700 on it and then Autoglym HD wax on top and since then have done nothing ... I see that all my windows need attacking..... Edited July 5, 2017 by JAS21 Link to comment Share on other sites More sharing options...
Anythingleft? Posted July 5, 2017 Share Posted July 5, 2017 I tried all sorts of potions and powders to remove the limescale from my car windows, in the end I used a razor blade in a handle attachment that you would use for paint work. Everything that I tried failed, vinegar, cleaning compounds and dedicated limescale remover. Bitch of a time consuming job but did manage to get rid of it in the end. All the write ups about vinegar and suchlike they had no effect on my cars windows....Sent from my SM-G900F using Tapatalk Link to comment Share on other sites More sharing options...

JAS21 Posted July 6, 2017 Share Posted July 6, 2017 If you rub your paintwork with newspaper, even wet newspaper, I suggest that you may be disappointed if you give your paintwork a close look later. Glass coating will not stop water marks ... the longer you leave them the worse will be the damage. Tesco Wash and Wax, we should all try it ...
