Prior to mattress cleaning be sure that your drying conditions are adequate. Ventilation from an air conditioner or fan will insure that you are only off your mattress for one night. If conditions are less than perfect your mattress will take longer to dry. Some of my clients have been able to use their mattresses the same night when left in direct sunlight. Mattress extraction and sanitation only will leave your mattress ready for use in approximately two hours. A double sided mattress may take longer to dry. A double sided mattress should also be left to dry on its side and occasionally rotated to insure that it dries evenly. Heavily soiled mattresses may also take longer to dry.
The sanitising products and extraction service that I provide will ensure that your mattress is dust mite free for up to six months, the dust mite spray that I use has been tested and approved to stop any reinfestation of dust mites for this period.
Padding the area until most of the liquid is important, use a white towel and press gently around the area until no more moisture can be soaked up. Apply a generous amount of baking soda to the affected area. At this point you can place a towel over the area, re make the bed and go back to sleep. Vacuum up the bi carb of soda the next day. You can repeat this bi carb/vacuum treat as often as you like, bi carbonate soda is simply the best way to absorb as much moisture as possible. Calling me within the next few days to professionally clean and sanitise your mattress would be your next best course of action.
