Best Glass Sealant after HW removal?


I only skimmed past threads, but didn’t see what I was looking for.

What do you guys use after a hardcore acid hard water removal job to protect the glass?



I also charge top dollar because it lasts for 6 years and counting


J Racenstein 3 Star Barrier is simply the best glass sealant by far. User friendly. No solvents. Stores well. A little pricey, but just pass that onto the customer.


I have been using Bio Clean remover (high speed buffer and soft pad) and Bio Clean sealant on shower glass, works pretty good.
Have tried Enduroshield also, good also.
No product last for years in shower, if it’s used daily, so has to be done once or twice a year.
