You could try wearing goggles + gloves + full sleeve clothing while spraying. Possibly a respirator rated for that type of solvent if you are spending lots of time around it. Be aware of the type of gloves necessary to handle the solvet. I believe latex gloves do not protect against xylene-based brake cleaners..!

For general degreasing, you could try substituting a water-based cleaner, like Simple Green or one of those citric acid based degreasers. Most are non-toxic, although the citric acid ones can be flammable.
