I need to remove VERY heavy water spots on a client’s windows without scratching it;)
Would you recommend using Bronze Wool or White Pad or Red Pad?
Which would you pick as I will be using it with BioClean or A1 Stain Remover?
Sounds more like a job for Mr. Hardwater or glass renu

Never, ever use a red pad. They will scratch a window. If the deposits are that heavy I’d suggest OneRestore or Glass Renu.
Great…thank you for the advice:cool:
Unfortunately any of those can scratch the glass including Bio-Clean on a micro-fiber cloth. (I’ve never used A1) I have the Mr. Hardwater system and it works great without scratching. I haven’t tried using the Micro Mineral Powder by hand yet, but others who have might can tell you whether that would scratch the glass or not. Personally I don’t care for the liquid acids, but they don’t scratch.
Chip - are you saying you’ve scratched glass with a white pad?
mr hardwater
Curious as to why the Micro Mineral Powder would not scratch by machine, but questionable by hand?
When I’m able to afford it…the Mr Hardwater system looks like the way to go…
No, sorry. I don’t have experience with the white pad. I have scratched glass with Bio-Clean, Bronze Wool, Steel Wool, and only heard Red Pad scratches.
Was the scratching on tempered or heat strengthened glass?
Don’t know if it would or wouldn’t. I do know that some rubbing compounds used on a painted finish do not scratch when used with a buffer but will scratch when rubbed by hand. Therefore, since I have not tried the MMPowder by hand I did not feel comfortable recommending it be used that way. I bet Doc has used it by hand.
Chip,
Thanks for the reply!
Hey Doc,
What ya say???
Thanks gents:cool:
French panes, 0000 bronze wool (plate glass), Outdoor lantern, 0000 steel wool (plate glass), and Automobile glass, not windshield, Bio-clean (Idunno glass) all done trying to remove hard water damage.
The auto glass (side windows I assume) would be tempered as would the French panes. The outdoor lantern I’m not sure about. However since it was steel wool it could have been rusty and caused scratches. The french door tempered could easily been defective. As for the auto glass it could have had scratches from other things and you just uncovered them. Just my opinions though.
The french panes are not in the door or next to the door and I really think it is plate glass. It’s due to be cleaned again in a few months, so I will check it out again. Dead give away if any panes are cracked.
New steel wool used on the lantern glass, really caught me off guard when I saw what it did to the pane ($7.00 replaced it). My advice is just don’t attack a piece of glass with anything without testing an area or two first, no matter how it has worked for you in the past.
Think you are right about the auto glass. Tempered side and rear windows, laminated windshield.
