How to Clean Fossils in OSRS: A Step-by-Step Guide for Beginners


Old School RuneScape (OSRS) offers a variety of unique activities, and cleaning fossils on Fossil Island is one of the most rewarding yet often overlooked tasks. Whether you’re aiming to earn kudos for the Varrock Museum, gain Prayer experience, or simply explore the island’s mechanics, knowing how to clean fossils efficiently can enhance your gameplay. This comprehensive guide will walk you through everything you need to know about cleaning fossils in OSRS, from preparation to practical tips, all while keeping it SEO-friendly for players searching for this niche topic.

Fossils in OSRS aren’t just random collectibles—they serve multiple purposes that can benefit your account progression. Cleaning fossils is a key step to unlocking their potential, whether you’re a completionist or a skiller. Here’s why it’s worth your time:

Unlock Rewards at the Varrock Museum

Cleaned fossils can be used to complete displays in the Varrock Museum’s Paleontology Exhibit. Each display you finish grants 2 kudos and an experience lamp, ranging from 2,000 to 5,000 XP depending on the fossil type. This is a fantastic way to boost skills like Herblore or Slayer without grinding.

Gain Prayer Experience

Alternatively, fossils can be enriched at the Mycelium Pool and turned into enriched bones, offering Prayer XP from 250 to 2,500 per bone. This method is especially useful for Ironmen or players looking for unique training options.

Trade for Numulites

If you’re short on Fossil Island’s currency, numulites, you can trade unidentified fossils to the Fossil Collector. Rates range from 100 to 500 numulites, making this a low-effort way to fund activities like Volcanic Mine.

Preparing to Clean Fossils: What You’ll Need

Before you start cleaning fossils, you need to gather the right tools and unlock access to Fossil Island. Proper preparation saves time and ensures a smooth process. Here’s how to get started:

Complete the Bone Voyage Quest

To access Fossil Island, you must complete the Bone Voyage quest. Speak to Curator Haig Halen at the Varrock Museum, and ensure you have the following prerequisites:

  • Quest Requirements: Completion of The Dig Site
  • Skill Requirements: 100 kudos (earned via museum activities)
  • Items Needed: 2 planks, 2 nails, a hammer, and a saw

Once completed, you’ll unlock the barge to Fossil Island, where fossil cleaning begins.

Gather Cleaning Tools

To clean fossils, you’ll need specific gear. Fortunately, these are easy to obtain on Fossil Island:

  • Leather Boots and Leather Gloves: Equip these before cleaning.
  • Trowel, Rock Pick, and Specimen Brush: Grab a cleaning kit from the crate near the cleaning bench or the Varrock Museum’s cleaning area.

Pro Tip: Keep these items in your inventory to avoid unnecessary trips.

Build the Cleaning Bench

The Archaeologists’ Cleaning Bench is essential for fossil cleaning on Fossil Island. To construct it:

  1. Head east of the Museum Camp.
  2. Use 5 planks, 5 nails, and a hammer (requires 5 Construction).
  3. Gain 100 Construction XP upon completion.

Alternatively, you can use the specimen table in the Varrock Museum if you’re already on the mainland.

How to Clean Fossils: Step-by-Step Process

Now that you’re prepared, let’s dive into the actual cleaning process. Follow these steps to transform unidentified fossils into usable items:

Step 1: Collect Unidentified Fossils

First, you need fossils to clean. Here are the best methods to gather them on Fossil Island:

  • Cutting Sulliuscep Trees: Requires 65 Woodcutting; yields up to 100,000 XP/hour and fossils.
  • Herbiboar Hunting: Needs 80 Hunter; a slower but passive method.
  • Fishing/Mining: Less efficient but viable for variety.

Step 2: Head to the Cleaning Bench

Take your unidentified fossils to the cleaning bench on Fossil Island or the specimen table in Varrock Museum. Ensure you’re wearing leather boots and gloves and have your tools ready.

Step 3: Clean the Fossils

Interact with the bench or table, and use an unidentified fossil on it. The game will automatically clean it, revealing one of these types:

Fossil Size Possible Outcomes Use
Small Limbs, Spine, Ribs, Pelvis, Skull Museum Displays (2,000 XP Lamp)
Medium Limbs, Spine, Ribs, Pelvis, Skull Museum Displays (3,500 XP Lamp)
Large Limbs, Spine, Ribs, Pelvis, Skull (or Plant Fossils) Museum Displays (5,000 XP Lamp)
Rare Limbs, Spine, Ribs, Pelvis, Skull, Tusk Prayer XP or Numulites

Note: Large fossils have a 50/50 chance of becoming plant fossils, which can slow museum completion due to RNG.

Step 4: Store or Use Cleaned Fossils

Store cleaned fossils in any fossil storage crate (contents sync across all crates). Decide their fate—museum displays, Prayer XP, or numulites—based on your goals.

Tips and Tricks for Efficient Fossil Cleaning

To maximize your fossil-cleaning efficiency, consider these practical strategies:

Optimize Fossil Collection

Focus on Sulliuscep trees for the fastest fossil drops. Wear a graceful outfit and bring antipoisons, as the Tar Swamp is hazardous.

Batch Cleaning Sessions

Collect a large batch of fossils before cleaning to minimize travel time. Use the bank chest near the cleaning bench (construct it with 2 oak planks, 5 nails, and a hammer) for quick storage.

Prioritize Museum Displays

Complete small and medium displays first, as they require fewer fossils (70 small, 60 medium) compared to large/plant displays (25 each). This balances RNG frustration with steady rewards.

Use Excess Fossils Wisely

After finishing the museum, turn rare fossils into enriched bones for Prayer XP or trade them for numulites to fund other Fossil Island activities.

Frequently Asked Questions About Fossil Cleaning in OSRS

How Many Fossils Do I Need for the Varrock Museum?

To complete all displays, you’ll need:

  • 70 Small Fossils (14 displays)
  • 60 Medium Fossils (12 displays)
  • 25 Large Fossils (5 displays)
  • 25 Plant Fossils (5 displays)

Total: 180 fossils, yielding 72 kudos and 120,000 XP across lamps.

What’s the Best Way to Get Fossils Fast?

Chopping Sulliuscep trees is hands-down the fastest method, offering both fossils and high Woodcutting XP. Pair it with birdhouse runs for passive gains if you’re multi-skilling.

Can I Clean Fossils Without Construction?

No bench-building skills? No problem! Use the specimen table at the Varrock Museum instead—it requires no Construction level and works just as well.

What Should I Do with Rare Fossils?

Rare fossils don’t fit museum displays yet, so either enrich them for 2,500 Prayer XP each or trade them for 500 numulites. Stockpile them if you’re hoping for future content updates!

Cleaning fossils in OSRS is a rewarding side activity that blends exploration, skilling, and tangible benefits.
