Landlord many stop tenant's LAUNDRY MACHINE use at any time

[Peace Lily]

Dear BP Members,

On my Rental Lease Agreement, there is a clause, "if any, are used at Tenant's risk and cost. Instructions must be followed.  Landlord may stop their use at any time." 

My rent includes the use of laundry machines at free of charge. I rent the apartment per room basis (majority graduate/post doc students).  This tenant asked me to remove this clause before his lease renewal.  Do any other landlords have this clause on their lease for protection purpose? What should I address to the tenant? He has been a good tenant for the 1st year so far although he can be picky... 

Thank you very much for your advise in advance!

@Peace Lily the immediate response would be "Why are you planning on damaging my equipment?" "No! Then you don't have anything to worry about."
