It is frustrating to spend time cleaning an item, only for it to still look dirty after the chore is complete. Water spots left on shower screens after the screen has been wiped over with glass cleaner is one such frustration. Since you are fed up with looking at the water spots on your shower screen, the good news is there are some products out in your garage which can take care of this problem for you. These are the three products which can make your shower screen clear again.
Most homes have a can of WD-40 or similar spray lubricant lying around the home, ready to be used on squeaky door hinges. WD-40 also works for removing water spots from shower screens and frames.
Water spots are buildups of mineral acids, and spray lubricants like WD-40 contain mineral spirits which dissolve these buildups. Simply spray the lubricant onto the water spot, let it sit for an hour or two, and then scrub clean using an old toothbrush. Don't use a steel wool ball to scrub your shower glass clean, as this will leave tiny scratches which will trap dirt and soap scum.
Another product you may find already out in your garage is a headlight restorer kit. A headlight restorer removes the milky buildup on car headlights that restricts the effectiveness of headlights once they're turned on. The headlight restorer kit is made up of two parts, which are the glass cleaner and the abrasive polisher. Do not use the abrasive polisher on your shower screen because it can leave the same fine scratches as a steel wool ball does.
However, the glass cleaner portion of the kit should dislodge the water spots once applied to the glass. Apply the cream to the spots and leave it on for the amount of time recommended in the instructions. Remove it with a damp cloth after this time has passed. Buff over the screen with a polishing cloth, and the water spots should be gone.
A steam cleaner kept out in the garage for cleaning car seat fabrics is a third option for getting the shower screen clean. Fatty acids from your soap can absorb into the glass and are the cause of some dirty spots. Holding a steam cleaner onto the glass over the spot allows the steam to penetrate the acid and dissolve it away. The shower screen can then be cleaned using standard glass cleaner.
If none of these three options removes the water spot for you, contact your local shower screen supplier to see what removal methods they can recommend.
