Cleaning a composite resin sink...

  Quickbeam 10:27 04 Oct 2017

Anyone living in a hard water area with an resin sink and know how to make it sparkle again?

No matter how well I clean it, it dries with a dull limescale film on it. It doesn't help that I've got the black one rather than the cream ones which can disguise the limescale!

I've tried all the vinegar and other suggestions that are flying around the internet, but to no avail...

I tried the oil method, but it leaves a sticky residue that attracts dust and fluff!

You have damaged the surface (it's become pitted) and the problem is insoluble. I'm afraid that that is a problem with Resins.

"You have damaged the surface"

Not over the entire surface are of a sink + half and drainer!

It's evenly dulled over the entire surface area over 4 years of normal kitchen use.

Many common kitchen chemicals damage resins. particularly some of the, what are known as, Surface Cleaners.

Modern resin composite sinks are incredibly tough, and will not usually be damaged by ordinary chemical cleaners - the risk is actually greater where wastes are concerned, so care is needed.

Oddly enough, black sinks are the most difficult of all when it comes to maintenance - they tend to show every trace of limescale, whereas other colours don't. Whatever you do, don't use bleaching agents - tempting as it might be.

You can safely try cleaners like Cif if the vinegar method hasn't worked, and at the same time gently scrape the limescale away with a plastic scouring pad. Keep at it, and when you get the sink looking better, introduce a drying regime - wipe the sink clean of all water after each use, it's the only way.

Have you tried one of the baby sterilising tablets/liquids? These are ideal for removing stains from cups etc and also from a composite Franke sink we had.

Have you considered a decent water softener, not to clean the sink but to reduce the effects of hard water in general.

A friend that has the same problem is using silicone spray that plumbers use to make the threads on plastic plumbing and rub it in with a paper towel and claims that it's good for a month at a time.

I'll get some at the weekend to try.

Worth a try, never used it on a resin sink but very handy for all sorts of things. About £6 a can the last time I bought some.

I gave the sink a spray and rubbed it last night, it came up very glossy like when it was new, and so far it is still shiny like when new without drying with the matt lime film, and the water forms into drops as on a waxed car. It did that when it was new.

Lets see how long it lasts with one spray.
