Works good but doesn’t make the house smell nice
Size: 8 Fl Oz (Pack of 2)
This works good in our robot vac/mop however it doesn’t make the house smell good when the house is mopped, just when you put it in the water tank. The floors are clean and that’s all I really care about but would it be nice to smell freshly mopped, yes.

A Reliable, High-Gloss Detailer That Delivers Professional Results Every Time
Style: Last Touch Spray Detailer - 1 Gal, Style: Last Touch Spray Detailer - 1 Gal
Meguiar’s Last Touch Spray Detailer has become one of the most dependable products in my detailing setup. After using it extensively on multiple vehicles, I can confidently say this detailer offers excellent performance, strong versatility, and outstanding value for anyone who details regularly or professionally.
The gloss and finish it provides are consistently impressive. It gives the paint a clean, slick, high-gloss look without feeling oily or artificial. On darker colors—where streaks are usually a challenge—Last Touch wipes off cleanly and evenly. The finish looks polished and refined, making it ideal for final wipe-downs before delivery or photography.
One of its biggest advantages is versatility. It works extremely well as a quick detailer for removing light dust, fingerprints, and water spots, but it also functions as an excellent clay bar lubricant. When diluted 1:1 (for the concentrated version), it provides smooth glide and reduces the risk of marring. When used at full strength, it delivers maximum shine with minimal effort. The ability to use one product for multiple steps adds a lot of convenience to any detailer’s workflow.
It has a mild, pleasant scent and buffs out effortlessly without smearing on glass or trim. It’s also very effective as a drying aid after a wash, helping prevent water spots while adding noticeable gloss.
The gallon size is a major value point and lasts a long time, especially for professionals or frequent users. However, it is important to double-check the product description before purchasing, as there is potential for confusion between the concentrated version and the ready-to-use version.
When I purchased mine, the photo on Amazon showed the concentrated gallon, which can be diluted, but what I received was the ready-to-use version, which cannot be diluted the same way. The seller never responded to my messages, but Amazon eventually issued me a refund. This does not reflect on the quality of the Meguiar’s product itself, but customers should be attentive to the listing details to ensure they receive the version they expect.
Overall, Meguiar’s D15501 Last Touch Spray Detailer is a high-performing, professional-grade product that consistently delivers excellent results. Whether used as a quick detailer, a clay lubricant, or a finishing spray to enhance gloss, it excels in every application. Highly recommended for both weekend enthusiasts and professional detailers—just be sure to verify which version of the product you are purchasing.
