How can I get heavy water spots off my windows. It appears to be heavy minerals. I have tried Windex and even lime away with a piece of worn out Scotch brite with minimal success.

no fix other than a complete overhaul .

Water spots after drying is an indicator of hard water (calcium-lime and other minerals) Bore water or other than town water. It may be necessary to use a light buffering cream after drying to remove the marks

hi these ar caused by either severe heavy braking like locking up the wheels in a skid will cause the rubber to be worn away by the road llike a cheese grater
or if a tyre is old and has been under inflated with air can become misshapen
either way the solution is to replace your tyres that are affected and maintain the correct pressure

Most floor leaks that show up after sitting in the heavy rain are leaking windshields...have you had your windshield replaced before? (The windshield installation should be under warranty...at least 1 year:) If you are driving and the floorboard is filling up...the floorboard itself must have a hole or plug missing...The VW usually has floor drain plugs located under the carpet...from your description, the windshield is probably the cause...are there any window trim pieces missing? This is an annoying problem...you can also test the windshield by having someone run a garden hose on the outside while you look inside for the penetration spot or spots...Hope this helps. A glass shop might do a free inspection...

I would guess a bad spark plug wire. Moist air will provide a path for the spark to jump to ground from a bad plug wire. You could test with a windex bottle filled with water and spray the engine in different spots. Also check for moisture under the distibutor cap.

My brother had the same problem with his pontic grand am, only it was the front windshield but all he had to do is get the proper weatherstripping and put it in. It solved the problem of rain leaking into the front pass. floorboard. I dont know if that will solve your problem but its worth a shot right???? Goodluck

Hi,

Follow the below steps ;-

1. Clean your window as normal, with a lint-free cloth. Spots left over from acid rain are sometimes difficult to discern from simple water spots--with luck, your glass is only dirty, and not damaged. Follow up the initial wipe-down with an application of Windex. Try to let the window dry out of direct sunlight, in order to prevent ugly streaking.
2. Dust the spots with a thin layer of baking soda (sodium bicarbonate). Take a damp rag, and scrub the water spots with a liberal amount of elbow grease. The baking soda is an effective, readily-available abrasive medium that will remove the spots without damaging the underlying glass. For an extra abrasive edge, consider scrubbing with an old toothbrush. If the spots persist, however, move on to Step 3.
3. Apply a small amount of cutting compound to a super-fine (Grade #0000) steel wool soap pad. Cutting compound suspends an abrasive in a paste that can then be applied to your glass, and the soap pad will scrub more effectively than a simple cloth. Do a test on a small patch of glass before you apply this method to the whole window, to ensure that your window will endure treatment.
4. Attack any remaining spots with the same amount of vigor and elbow grease--acid marks can be incredibly persistent, and at this point you're polishing more than you are cleaning. After an appropriate amount of effort, check to see if any stains still persist. If stains are still readily detectable, try repeating this step while using a cutting compound of smaller grit size.
5. Assess the final result, after all reasonable effort has been exhausted. As the name suggests, acid rain actually etches into the surface of the glass. If the damage is extensive enough that it impairs the functionality of the window, you may have to bite the bullet and obtain new glass.

Let me know, if need further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

check for poor flow to heater core-change heater hoses -check for lime build up at intake connector or worn out water pump -if you only put water through core try using CLRlime cleaner in core-get two 6in pieces or heater hose hook them to core and pour it in and leave for 15 mins then wash out with water hose

Windex and newspaper should do. You sure they are water spots and not the glass? When they set out the plastic impregnated in the glass (safety glass), seperates slightly and looks like a water spot or even a bubble. It is a combination of heat & sun rays. May have to live with it or replace the glass.
