10 Best Paint Thinner Alternatives

Paint thinner is a product that can be used for various purposes. Some are designed for cleaning brushes, surfaces, and spills, while others are used with oil-based paints and stains to thin them out and make them easier to apply.

However, paint thinners can be dangerous and harsh on the environment. In this guide, we will be discussing some of the best paint thinner alternatives that are safer and more effective.

Various Uses of Paint Thinner

A paint thinner can be used in different ways depending on the paint you’re using and the project you’re working on.

Paint thinner cans

Here are some common uses for paint thinner:

Thin oil-based paint

You can use paint thinner to thin out oil-based paint so that it’s easier to apply. That’s especially useful if you’re painting a large surface and need to cover it quickly.

Clean up surfaces

The paint thinner can also be used to clean previously painted surfaces that might have some residual paint or other debris.

Clean brushes

You can soak the brushes you used to apply oil-based paint in paint thinner to clean them.

Degrease surfaces

You can use paint thinner to degrease surfaces before painting them.

Wipe up spills

If you accidentally spill oil-based paint, you can use paint thinner to clean it up.

Extend paint’s life

You can add paint thinner to oil-based paint that has been sitting for a while and has started to thicken. That’ll make the paint easier to work with and extend its life.

Improve spray applications

When using oil-based paint in a sprayer, you can add paint thinner to improve the application.

What Happens if You Don’t Use Thinners?

If you use oil-based paint and don’t thin it out, it’ll take much longer for the paint to dry.

It can also be challenging to apply the paint evenly and could result in an uneven paint job. In addition, the paint:

  • Might drip or sag
  • Can become too thick to be sprayed through a paint sprayer
  • Won’t level out properly, which can give your walls an unsightly texture
  • Might not adhere to the surface properly, leading to peeling or flaking
  • The paint job will likely take much longer to complete since you’ll have to work harder to apply the paint evenly.

How to Choose a Paint Thinner Alternative?

When choosing a paint thinner, you’ll need to consider:


Paint thinners vary in price, depending on the brand and the type of solvent. Choose the one that fits your budget.

Type of paint you’re using

Some paint thinners are only meant to be used with oil-based paints, while others can be used with any paint.

The project you’re working on

If you’re working on a large project, you’ll need to buy a larger quantity of paint thinner.


Some paint thinners are more toxic than others. Choose one that’s safe for you and the environment.


Choose a paint-thinner alternative that is less flammable if you’re looking for a safer option to use indoors.

The scent

Some paint thinners have a strong chemical smell, while others are more pleasant to work with.

The surface you’re painting

Some paint thinners are more abrasive than others. Choose one that’s gentle on the surface you’re painting.

Your personal preferences

Some people prefer using less toxic or more pleasant-smelling paint thinners, while others don’t mind the strong chemical smell.


If you’re looking for an eco-friendly option, consider a paint thinner alternative made from natural ingredients and doesn’t contain petroleum-based solvents.
