Many different volatile liquids will work when replacing golf grips with typical grip tape that deactivates with the application of golf solvent. Mineral spirits, denatured alcohol, acetone, nail polish remover, or charcoal lighter fluid can all deactivate grip tape sufficiently to install new grips. Charcoal light fuel is a natural product and so is safe to use as a solvent. The most effective solvent for removing old grip tape is mineral spirits. Other substances may also be used but they will not remove the tape as completely. Mineral spirits are available at any home improvement store for a cost of about $10 for 1-gallon bottle. They are inexpensive compared to other solvents that might be considered but they are also toxic if not used properly. The vapor from mineral spirits is also harmful if not removed by some form of ventilation. Acetone and denatured alcohol are also useful as solvents but they are more expensive than mineral spirits. Nail polish remover is even more expensive but it is extremely effective. None of these substances should be ingested. They are all flammable and toxic if not used properly. Golf grips should be replaced every six to twelve months depending on how much exercise you get done around the course. Old grips become dry and hard due to excessive heat produced by your hands as you swing them around. This excessive heat causes the rubber in the grip to break down over time.
