Plastic basins

[janeerica]

My new-to-me motorhome is very tidy except the plastic basin in the bathroom which has yellow staining and so any tips you may have for returning it to a whiter shade of pale would be much appreciated. It really isn't the end of the world, and is just something I'd quite like to do. Internet tips seem to revolve around caustic soda which seems a bit harsh!
Regards Jane

Personally I would try using Jif. It wont scour the surface of the plastic and hopefully will get what is probably lime scale from the sink.

Trial and error I think.. if it's limescale

have you tried white vinegar.. or lemon juice.
or bleach..

Hi, be careful what you use as my showeroom sink disintegrated because I used the wrong product to clean it and it was expensive to replace it as it was a rapido model

Is it really staining, or has the plastic itself changed colour? You might be rubbing for ever if the composition and age of the plastic has time altered it.

Thetford toilet bowl cleaner can be used on washroom sinks. It cleans and also polishes. Not cheap, but worth a go see here for details.

the best solution for discoloured plastics is to paint them after thoroughly cleaning them. easiest and cleanest way is remove them from the van first

You shouldn't use bleach on any plastic in motorhomes / caravans it can and will discolour plastic and cause it to become brittle, some mouth washes also cause damage to the plastic, when we had a caravan with a normal cassette toilet when the bowl became slightly discoloured I used to fill it with a strong solution of warm water and puriclean leave it for a couple of hours and just drain and rinse worked a treat, then a wipe round with Lidl's W5 lime scale remover
