Hard water stains on your car are not just ugly — they can permanently damage your paint and reduce visibility through your windshield and windows. In India, due to borewell water and untreated municipal supply, hard water deposits are a common issue car owners face. These spots form when water evaporates, leaving behind minerals like calcium and magnesium on the surface.

But don’t worry — with the right technique and quality products, you can get your car sparkling again. Here’s a step-by-step guide to removing hard water stains effectively using Shinero car care products.

Step 1: Pre-rinse the Car Thoroughly

Before applying any product, use clean water to rinse the car. This removes loose dirt, dust, and any contaminants sitting on the surface.

✅ Pro Tip: Use a low TDS water source or filtered water if available to prevent new stains during the rinse.

Step 2: Wash with Shinero Gloss Pro – Wash & Wax Shampoo

Mix Shinero Gloss Pro in a bucket (1 cap per litre of water). Its pH-balanced formula is designed to gently remove mineral buildup without harming paint or clear coat. The added wax in the shampoo gives a mild shine and protection with every wash.

✅ Focus on the areas with visible white stains or dull spots during the wash.

Step 3: Use Shinero Glass Gleam for Windshields and Windows

Hard water stains on glass can drastically reduce visibility. Spray Shinero Glass Gleam directly on the windshield and wipe with a clean microfiber cloth. For tough stains, let it sit for 30 seconds before wiping.

💡 Dilution tip: For windshield washer tank use 1:20 ratio.

Step 4: Clay Bar for Stubborn Spots (Optional)

If spots still remain, gently rub a clay bar over the surface with Gloss Pro as a lubricant. This helps lift mineral deposits from microscopic pores in the paint.

Step 5: Protect with Shinero Ultra Wax

Once your surface is clean and stain-free, apply Shinero Ultra Wax to protect it from future water spots. It creates a smooth hydrophobic layer, preventing minerals from sticking to your car’s paint and glass.

Apply in circular motion, let it sit for 5–7 minutes, and then buff with a Shinero microfiber cloth for a deep, mirror-like shine.

Final Tip: Always Dry with a High GSM Shinero Microfiber Cloth

Never let your car air dry — it leaves fresh spots. Use a 1600 GSM Shinero microfiber towel to gently absorb water and leave a spotless finish.
