We have the same issue. Our house is updated except for the bathrooms, which we will not do before we move. Our shower door in the master was so corroded because our house is thirty+ years old. We tried everything, but what worked was the lemon brillo pads, and elbow grease. We got two estimates to replace; one was 740 and another was 900. Uh, no. Moving sucks.
Edit: My hub and I have made a pact. He says he will never let things go again as in fixing a problem right away, and I said I will never be a hoarder again.
Eighteen years of stuff has been really stressful; plus we are moving in 2 weeks. The housing market in SoMD sucks and we don't have our house up for sale yet; worse time of year and facing two mortgages. Oh, well. Life is short, and an adventure.
