You just need to use it with a microfiber cloth instead of the included white pads. **Q: It looks great for a while, but then after I use windex to clean the widows, the spots reappear. What are the longterm care instructions?** A: We have never heard of that phenomenon. If you live in an area that has very hard water, it may be wise to treat the glass with a hydrophobic coating after cleaning off the spots. Something like a Rain-X or Aquapel would help prevent more spots from reoccurring. **Q: Does this work on headlights?** A: It depends. Most modern headlight are made of Policarbonate. Older vehicles often had glass headlights. ProClean would work well on older glass headlights. However, it is not designed for use on clear plastic surfaces. **Q: can it remove other stuff on your windshield that are baked in spots** A: Yes and yes... this is the ONLY thing that has worked Period! A must buy if you want to remove those baked in acid rain spots. My only regret is that I stumbled upon it recently after years of trying various other products. Requires a significant amount of elbow grease to apply and buff... but the results are eyes poping and unbelievably sureal. Restores the glass to factory smooth shine and clarity! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works like magic *by E***D on 5 February 2025* I don't know what I would have done without this product, it is a pity it comes all the way from the USA to the UK. I would highly recommend this product, it works. ### ⭐ Does not work *by P***G on 24 January 2024* Was disappointed as this product does not work on my shower screen soap scum even scrapping with Bosch Cordless Universal Brush ### ⭐⭐⭐⭐⭐ I'd give this stuff 10 stars if that were possible. *by W***S on 5 October 2026* I daily drive a '98 Honda Civic Coupe I bought new. Recently I've been on a campaign to either replace or clean all glass on the car. I turned my attention to the quarter glass this summer, and since it's original it had over 28 years of wicked water spotting and embedded surface scum, despite regular car washings, and looked terrible. I was getting ready to have the glass replaced $$$$. The last time I had the windshield replaced, the tech showed me this stuff and recommended I try it on my dirty glass. After holding onto this stuff for a year, I finally gave it a go this weekend. The results are nothing short of amazing. My ancient quarter glass looks OEM new again. Not "better" or "improved" — it looks NEW. The hard water stains are GONE. I am thrilled with this stuff, and I am looking forward to tackling the rear windshield on this car — which is the worst piece of glass on the car. The quarter glass required three separate rounds / applications to achieve the above results, but it's easy to use with the supplied applicator pad, and not too messy. There's plenty of product in this size of bottle to do the entire car with some left over. I realize this might sounds like a paid endorsement. It most certainly is not. It's just a fantastic product, and I love supporting companies that offer effective and useful products that actually perform as advertised. ## Frequently Bought Together - GlasWeld ProClean Hard Water Spot Remover Kit for Water Spots on Glass, Metal & More - Includes Applicator Pad - Water Stain Remover for Glass, Shower Door Cleaner & Car Window - Homax 10120000 Steel Wool, 12 pad, Grade #0000, Rhodes American, Final Finish --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/465059821-glasweld-proclean-hard-water-stain-remover-for-glass-and-metal](https://www.desertcart.jp/products/465059821-glasweld-proclean-hard-water-stain-remover-for-glass-and-metal) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-31*
