Buying Guide
Choosing the right degreaser for heavy equipment depends on several factors. Here’s what to consider:
- Type of Degreaser: Solvent-based degreasers are powerful but can be harsh and have strong fumes. Water-based degreasers are safer and more environmentally friendly but may not be as effective on tough stains.
- Surface Compatibility: Always check if the degreaser is safe for the surfaces you’ll be cleaning. Some degreasers can damage paint, rubber, or plastic.
- Strength: Consider the severity of the grease and grime you need to remove. For heavy buildup, you’ll need a stronger degreaser. For lighter cleaning, a milder formula will suffice.
- Safety: Look for degreasers with low VOCs (volatile organic compounds) and non-toxic ingredients. Always wear gloves and eye protection when using any degreaser.
- Application Method: Some degreasers come in spray bottles, while others are concentrated and need to be diluted. Choose the application method that works best for your needs.
- Biodegradability: If you’re concerned about the environment, opt for a biodegradable degreaser.
