We recently had the task of pressure washing and removing the chewing gum from the entrances at Costco, Trafford Park in Manchester.
Due to the stores opening hours we worked through the night as not to cause any disruption to the business.
We first removed the chewing gum from the concrete paving using low pressure super heated water which is a extremely effective method of removing chewing gum. Once the area is clear of gum we then pressure washed the area with our flat surface cleaner which effectively cleans the paving without leaving any marks that you can get from only using a lance. Once we have rinsed down the store front and cleaned the run off in the car park we have totally transformed the store front making it fresh and welcoming.
