Hotels (or gyms) are not using cheap towels or cheap detergent and they use high temperature commercial washers.

Winter temperatures average in the mid-50s and not so oppressively hot in the summer making the area an excellent golf destination.4.

The contractor claims he can paint the siding of the house to match the garage but that he needs at least 2 days where the temperature is above 50 degrees and stays above freezing at night.
