Hi guys,

I'm a professional glass restorer and am constantly removing hard-water stains from car/boat windows, shower screens etc...

For stage 1 glass corrosion (95% of windows will have at least some of this), I use a product called Winsol Crystal Clear 550 (CC550). This usually removes most of the stains with ease. It works by dissolving the mineral build-up and is the quickest and least messy way of completing the job.

For more stubborn water spots (you can do it this way for light stains too), I use cerium oxide powder which is mixed with demineralised water to form a slurry. I then use a felt pad and polishing tool to polish the stains out. My polishing tool is worth over $1500 but for the DIY guys, you can use a felt pad (purchased from your local hardware store) attached to your household drill and remove the stains this way. It's a lot quicker than polishing by hand but if you have to go down that road, use Superfine Steel Wool (0000 gauge). This is abrasive enough to remove the stains but will not scratch the glass. I get all my supplies from these guys as they are the cheapest around http://fcwc.com.au/shop

Once the glass is restored, I apply a product called Sani-Shield which offers a lasting protection for up to 12 months from the hard-water stains forming again. A cheaper option is RainX

To clean the glass/window/shower screen, simply use soapy solution. You don't want to use anything too harsh otherwise you may compromise the protective sealant.

Something similar, my windows have started to rub on something inside the door and its lightly scratched them. I wanted to get the windows tinted but I'm scared the windows might continue to rub and wear the tint off or that when they lay the tint down the scratches will be seen through the tint. Any tips for maybe removing the scratches or help it from rubbing the glass?

its hard to explain but it basically looks like its peeling and stuff in spots?

i think thats what happened anyway, cos the tint on the familys XC90 was peeling and flaking off in places and when we showed it to tint a car their first reaction was - windex?

ive been told by people who install tinting and final inspection and other good detailers its just unsafe on tint

the people who installed the security tint/film on my house glass also told me not to use windex anymore - microfibre and warm water

the stuff we use to clean windows at my work seems like windex though - and it hasnt caused any damage and ive done more than a 100 cars with it ...

i just wouldnt risk it on any of my cars with so many professionals warning me against it

much cheaper in the long run to just buy a good MF and a good auto glass cleaning solution than to just use windex and find out one day in the future that it buggers up your tint imo

if someone with more knowledge could clear up exactly what it does to tint that would be great cheers.gif

amonia in windex kills tint, turns it purple and peals it off. use glass cleaner designed for tint or just clean water

Hi ,

If your water marks are on the surface of the glass you can remove them using a product by CarPro called Ceriglass. This a Cerium Oxide based product mixed with a nano polish to allow it to work by machine or with the applicator in the kit.

I have removed not only water marks but seriously deep windscreen wiper scratches on glass with this and a polisher. Definitely worth a try.

I have it on my chrome window surrounds and windows. I shall try the acetone trick on the chrome and windows and see how I got.

That Autoglym glass polish is as useless as tits on a bull

Where do you get this "ceriglass" you speak of?

JDM Performance,

Your right about that. The product I recommended called Ceriglass does contain cerium oxide as well as nano abrasive acting as a lubricant.

For me, I just clean with soft sponge and liquid soap. Though, hard stains can be clean by ceriglass. There are lot car glasses care material who is very effective in removing car glass stain. Though, it was depend in your usage.

      49719 is the cooler loop. Right at the front, LHS of that diagram. Return line from rack (LP side) goes to cooler loop on RHS front of car, then back under engine and returns to bottom of tank. 49717M is feed from tank to pump. HP line out of pump is thick rubber, followed by the hard line that runs down to crossmember and runs in parallel (but opposite flow direction) to the LP return line. Nothing goes anywhere near the firewall or interior of car. The closest they get to that is the connections on the rack.

      Thanks, plan is to drain all fluid tomorrow and do smoke test to find out the leak.   Appreciate your help and want to understand how the system work. So cooling is achieved by the long loop not any rad? The diagram seems to suggest it connects to somewhere inside the cabin and I thought that is a cooler inside firewall. If you look at the diagram it seems to show it connects to something inside firewall. I tried chasing it but not easy unless I take loads off   i am confident pump is good as fluid goes in and it gets soft( steering) but as soon as I turn engine off , loads of bubble come to surface and overflow. When engine is on , fluid level is below minimum but when off it shoots off and thinking it is sucking air in. I suspect aluminium pipe may have a crack line or whole   smoke test with no fluid should be a good start and if needed will remove the pump   In addition, the one going under the engine bay is high pressure line and one directly connecting from pump to resorvoir is return/ low pressure?   finally I searched and suggestion is to use dexron 2 but that is discontinued so bought dexron 3 as all research suggest it is compatible and shouldn’t cause any issues/ blow seals. I bought two liter of dexron 3 motul atf

      Don't worry about. Just don't try to drive hard enough to make boost and you'll be fine.

      Yes. This has already been said. It is a loop of hardline in front of the radiator. Because.... the pump is on the LHS and the steering rack hydraulic connections are where they always are on a RHD steering rack....on the RHS. The high pressure line goes down under the engine, along the crossmember, like it does on all Skylines. Don't just throw expensive braided hoses/other kits at it. Work out what is wrong and fix that.

      Still got the afm on the intake, clamps are shut tight, only loose hose is the one that goes from the j pipe towards the IACV, since it's next to impossible to find a factory hose and the barbs are different sizes (I'm still using clamps on this hose to try and help it seal on the iacv side) I've ordered parts to make up the hotside of the intercooler pipes, I'll plumb it in and see what happens in a few days I suppose The turbo's internally gated, can I just unscrew the tension rod to let the gate open?
