Does Cleansing Foam Work on DDTs? A Deep Dive into BTD6 Mechanics

▶

Yes, Cleansing Foam is effective against DDTs (Dark Dirigible Titan) in Bloons Tower Defense 6 (BTD6). This surprisingly powerful tool not only removes the camo and regrow properties from these formidable bloons, but also weakens them by stripping their lead layer. This makes Cleansing Foam a key component in many advanced strategies, especially on more difficult challenge modes like CHIMPS. This article will delve into the mechanics of Cleansing Foam’s interactions with DDTs, as well as answer frequently asked questions about DDTs, Cleansing Foam, and related BTD6 strategies.

Cleansing Foam: More Than Just Decamo

How Cleansing Foam Works

Cleansing Foam, typically accessed through the Monkey Sub’s 0-3-0 upgrade (Submerge and Support), deploys a burst of foam that clings to bloons. Upon contact, the foam:

• Removes camo properties: This makes DDTs visible to towers without innate camo detection.
• Removes regrow properties: Prevents bloons from regenerating layers over time.
• Strips lead properties: Specifically, for DDTs, this means they lose their lead layer, becoming vulnerable to standard damage types. Crucially, Cleansing Foam damages normal Lead Bloons, turning them into Black Bloons. However, it does not damage DDTs other than stripping lead, allowing for a unique interaction for strategy.

The foam disappears after cleansing 10 bloons (or 15 with the 0-3-1 or 0-3-2 upgrades), or after about 8.5 seconds. Its effect is not permanent, but when well-timed and paired with other towers, it can be devastating to early and mid game DDT rushes, and weaken DDTs for end game damage dealers.

The DDT Advantage

DDTs are fast, camo, lead, and black bloons; this makes them one of the most challenging mid to late-game threats. They require specific counters due to their numerous properties. Cleansing Foam is particularly valuable because of its versatility, offering camo stripping, regrow stripping, and lead stripping (for DDTs only) all in one package.

Cleansing Foam and Overclocking

The utility of Cleansing Foam is especially evident when paired with Overclock (Engineer Monkey 5-2-0). By overclocking your Cleansing Foam Sub, the rate of foam deployment increases, allowing you to clear waves of DDTs faster and more efficiently. This combination is particularly effective for tackling “All Pops CHIMPS” challenges, where all damage must come from a limited number of towers.

Frequently Asked Questions (FAQs)

Here are 15 frequently asked questions about Cleansing Foam, DDTs, and relevant BTD6 strategies, addressing common questions and confusions:

1. Does Cleansing Foam remove lead from regular Lead Bloons? Yes. Cleansing Foam damages regular Lead Bloons, and converts them into Black Bloons, this does not occur with DDTs. It strips DDTs of their lead property, making them vulnerable to non-piercing attacks that can’t pop leads.
2. Does Cleansing Foam damage DDTs? While Cleansing Foam damages Lead Bloons, it does not directly damage DDTs. It only removes their camo, regrow, and lead properties.
3. Can DDTs be stripped of their camo? Yes, Cleansing Foam, Submerge and Support (Monkey Sub 0-3-0 or higher), and Signal Flare (Mortar Monkey 0-2-0) can remove the camo property from DDTs.
4. What are some other good counters against DDTs? Besides Cleansing Foam, Icicle Impale (Ice Monkey 5-0-2) under a 2-3-0 Village for both damage and slowing, and a Pre-Emptive Strike (Monkey Sub 0-5-0) are effective against DDTs due to their damage output against MOAB-class bloons.
5. How does Submerge and Support work against DDTs? When set on the “Submerge” targeting mode, this upgrade does not attack with darts. Instead, it produces a no-damage radar attack that decamos all camo bloons, including DDTs, at intervals.
6. Does Shimmer Wizard work against DDTs? Yes, while Shimmer does provide detection, you’ll want towers to deal damage to the DDTs. It also adds camo detection to a large radius, which can be useful. The most cost-effective is usually an MIB Village (Monkey Village 0-3-0).
7. Does Moab Press work on DDTs? No, Moab Press is not as effective against DDTs and BADs. It’s useful for stalling regular MOAB-class bloons, however, you will need other towers to deal with DDTs if using Moab Press.
8. What towers work well with a Cleansing Foam Sub? Towers that can deal with a large number of bloons very quickly such as Glaive Lord (Boomerang Monkey 5-0-0), Apache Prime (Heli Pilot 5-0-0), and Tack Zone (Tack Shooter 5-0-2). These towers can very easily handle the waves of ceramics that DDTs can drop.
9. Does Master Bomber work well against DDTs? Yes, Master Bomber (Ninja Monkey 5-0-0) deals significant grouped and single-target damage against DDTs, especially when boosted by Shinobi Tactics (Ninja Monkey 1-0-3). However, it can struggle with large groups of Ceramics and normal bloons.
10. How do you deal with grouped DDTs? Grouped DDTs can be handled with crowd control towers like MOAB Glue (Glue Gunner 0-2-4), as well as high-damage towers like Apache Prime and Tack Zone.
11. Is Sticky Bomb a good counter to DDTs? While Sticky Bombs can stick to DDTs, their speed and the timer on the bombs make it less effective. Using Sticky Bomb alongside another primary dps unit would be beneficial.
12. Why are DDTs so dangerous? DDTs are dangerous because they are fast, camo, lead, and black bloons. This combination makes them resistant to many standard attacks and requires specific countering.
13. How many bloons can Cleansing Foam affect? The foam disappears after affecting 10 bloons (or 15 with 0-3-1 or 0-3-2 upgrades) or after about 8.5 seconds.
14. What are some common mistakes when dealing with DDTs? One of the biggest mistakes is relying solely on towers without camo detection or lead-popping capabilities. Players should also prepare to be able to handle ceramics that the DDTs will spawn.
15. What is the best way to learn how to counter DDTs? Experiment with different tower combinations and understand what each tower can do, and what the DDT weaknesses are. Practice with different strategies and be ready to adapt to each round. Try the sandbox mode, and experiment there with the settings you would expect to see late game.

Conclusion

Cleansing Foam is a powerful and versatile tool for handling DDTs in BTD6. Its ability to remove camo, regrow, and lead properties (stripping Lead from DDTs specifically), makes it an invaluable asset. When combined with strategic tower placement and other complementary towers, it is key to winning difficult challenges. Understanding the mechanics of Cleansing Foam and its interactions with DDTs is essential for mastering advanced gameplay in BTD6.
