Hi, I'm very sorry that you have not experienced the expected results. Can I ask did you use the Diamond Sponge to clean the oven? The reason I ask this, is ekoWorx is typically not aggressive enough to tackle baked on foodstuffs.
Maybe I can help by asking you a couple of questions... Are you cleaning the shower area when it's wet? If so then try doing it when the whole area is dry as that can help. Also, make sure you use dry cloths and not wet/damp cloths. Also, using the Diamond Sponge gently is highly effective on built up soap scum - have you tried this?Failing that, if you're still not getting results then you may have to consider your screen could have soap scum etching (also known as shower cancer or chemical burn). Soap scum can permanently etch into glass and other surfaces and that's then a permanent issue. Unfortunately this is actually quite a common issue and is virtually impossible to restore. On the upside, ekoworx will have effectively cleaned your shower surfaces despite the cosmetic look and can be used to clean pretty much the rest of your home which I would encourage you to try if you haven't already done so. I'm happy to jump on a call so I can get this resolved for you. 🙏🏼 JustinÂ
