Been using Stjana for a year now could not speak any more highly of their products. Simple range rather than over complicated nonsense you see with others. But what happened this weekend has just cemented the fact this company is the best in the business. I had my car ceramic coated last year. Stjana came up on TikTok and I liked Cavs enthusiasm. So I messaged them to ask if their products were safe to use on ceramic coating and they recommended everything I would need! Without hesitation I brought the products and have used them ever since. Fast forward to this weekend my detailer who ceramic coated my car came round to complete a decon wash. The detailer informed me the coating has failed and is hardly present! I shown him what products I have been using as he wanted to raise a warranty claim with the supplier of the coating. The supplier comes back claiming Först is the reason the coating hasn’t lasted. Forst is not a harsh chemical in the pre made bottles which is all I’ve used. A coating should never fail in the space of 12 months when maintained! I messaged Stjana on Instagram and we had an in depth chat regarding the issue and Cav was very informative and made it clear his products do not ruin coatings if the coating is of good quality. He then did no more than offer to send me his own product Glatt free of charge because no doubt the glatt will last longer than the coating did. Completely unexpected and wasn’t necessary but the care for his customers is second to none and for that reason I will never buy another car cleaning brand!
