I replaced my liner during covid shortages and I was not able to get steps. They need replacement or a bath fitter for steps renovation. I have the bolts below the steps pushing through and I have metal stains on those bolts.
I have tried stain removers and vitamin C tabs with little to no Sucess. I also have some micro cracking on the surface. Any ideas on fixing it without ruining the liner ?
Thanks
