If you are one of those people who are afraid to invite a whole crowd in the house because they don't know how to deal with all the mess after the party, here are my tips for your carpet cleaning:
The first thing to do is to act fast. When your last guest leaves you better get started with the work which should be done. Otherwise, you might feel lazy but what's worse, the spots on the upholstery will become harder to clean.
However, if you don't have the proper cleaning detergents for the job you can simply use the vodka which got left. It is very good cleaning solution and it can get you rid of many different stains. The reason is that vodka is basically colourless alcohol, it has no odour and it is very cheap.
Of course this way you won't be able to deal with all the spots after the party but it will help you for most of them. However, if you need some professional help you can always hire a carpet cleaning London company. They are very good at what they do and they are charging expensive.
