The smell of burnt metal hangs for a while. Get out the eau de pine and mask it
Before I got rid of my Foley grinder I learned a trick that makes grinding more pleasant on two levels
Get a scented candle stub. Smellier the better. Once you have the grinding wheel dressed to the right radius take the candle stub and, while the wheel is spinning 'grind' some of the wax into the wheel. The heat will melt the wax into the pores of the abrasive wheel
When you grind the wax will melt a little and smell good
The wax cools the tooth a teeeeny little bit
Best of all the wax gives support to the grit in the wheel so that the grit doesn't wear away. This lengthens the intervals betweeen redressing
Now...get the smelly spray and sanitize the house. First, get the grinder out!
